History of the S50 and S52
BMW Motorsport launched the S50B30 in 1992 with single VANOS and individual throttle bodies. The 3.2 litre S50B32 of 1995 brought double VANOS and 321 hp. For North America, BMW built the S52B32 from an M52 block with an M50-style head and single VANOS.
1992: the S50B30 arrived with 3.0 L and 286 hp in the BMW E36 M3 3.0.
1994: the S50B30US arrived with 3.0 L and 240 hp in the BMW E36 M3 and BMW E36 M3 US. It was a lower-output version for smaller or more economical models.
1995: the S50B32 arrived with 3.2 L and 321 hp in the BMW E36 M3 3.2. Compared with the S50B30US, it added 81 hp.
1996: the S52B32 arrived with 3.2 L and 240 hp in the BMW E36 M3 US and BMW Z3 M. It was a lower-output version for smaller or more economical models.

Common S50 and S52 problems and what to check
No engine is perfect. These are the faults our workshop sees most often on the S50 and S52, what causes them and how to check a used unit before you buy.
Oil pump nut
The oil pump sprocket nut can back off, leading to sudden oil pressure loss. It is commonly safety-wired or replaced with a self-locking nut.
How to check: Ask whether the oil pump nut has been secured.
VANOS (S50B32)
The double VANOS unit can fail, causing rattle and loss of torque.
How to check: Listen for rattle at idle and check for fault codes.
Cooling system
Plastic expansion tanks, thermostat housings and impellers crack.
How to check: Look for a recent cooling refresh.
Valve cover and oil leaks
Gaskets harden and leak, especially around the VANOS unit.
How to check: Check the front of the head for oil.
Diagnosing a failing S50 and S52: symptoms and causes
If your current engine is showing one of these symptoms, this table helps you judge whether it can be repaired or whether a replacement S50 and S52 is the better route.
| Symptom | Likely cause |
|---|---|
| Knocking from the bottom of the engine | A deep knock that rises with engine speed usually means worn rod or main bearings. |
| Overheating or losing coolant | Coolant loss without visible leaks points to a head gasket or a cracked head; visible leaks point to the water pump, hoses, thermostat housing or expansion tank. |
| White smoke that smells sweet | Coolant burning in the cylinders, from a head gasket, a cracked head or, on diesels, a leaking EGR cooler. |
| Blue smoke | Oil burning in the cylinders. |
| Rough idle or misfire | Ignition coils, spark plugs, injectors and vacuum leaks are the usual causes. |
| Loss of power | Start with the simple things: air filter, boost leaks on turbo engines, fuel pressure and fault codes. |
| Rattle for a few seconds after a cold start | The classic sign of a weak timing chain tensioner or stretched chain. |
| Poor low-down torque and uneven idle | VANOS seals or solenoids. |
| Oil pressure warning or bearing noise at high revs | On M engines, a warning at high revs can be the first sign of bearing wear. |
Knocking from the bottom of the engine. A deep knock that rises with engine speed usually means worn rod or main bearings. Stop driving: bearing failure ends with a broken connecting rod. A used engine is normally the most economical fix once the bottom end is damaged.
Overheating or losing coolant. Coolant loss without visible leaks points to a head gasket or a cracked head; visible leaks point to the water pump, hoses, thermostat housing or expansion tank. Overheating should be fixed before it warps the head.
White smoke that smells sweet. Coolant burning in the cylinders, from a head gasket, a cracked head or, on diesels, a leaking EGR cooler. Check the coolant level and look for oil in the coolant.
Blue smoke. Oil burning in the cylinders. A puff on start-up points to valve stem seals; constant smoke under load points to piston rings or, on turbo engines, turbo seals.
Rough idle or misfire. Ignition coils, spark plugs, injectors and vacuum leaks are the usual causes. A misfire on one cylinder that moves when you swap coils is a coil; one that stays is a plug, injector or compression problem.
Loss of power. Start with the simple things: air filter, boost leaks on turbo engines, fuel pressure and fault codes. A gradual loss with poor compression on a test points to internal wear.
Rattle for a few seconds after a cold start. The classic sign of a weak timing chain tensioner or stretched chain. It must be checked quickly: a chain that jumps a tooth can bend valves.
Poor low-down torque and uneven idle. VANOS seals or solenoids. The engine may run well at high revs but feel flat and lumpy at low speed.
Oil pressure warning or bearing noise at high revs. On M engines, a warning at high revs can be the first sign of bearing wear. Check the oil level and stop driving hard until it is diagnosed.
Repair or replace your S50 and S52?
As a rule, bolt-on faults are worth repairing and internal damage is not. Seals, sensors, coils, injectors, pumps and turbos can be replaced in the car. Once the bearings, crankshaft, bores or head of an S50 and S52 are damaged, a used engine is usually cheaper and quicker than a rebuild.
M engines are expensive to rebuild because parts are costly and specialist labour is needed. A used M engine with documented bearings is often the better value for road cars.
Ask your workshop for a written diagnosis before deciding. A compression test, an oil analysis and a borescope inspection take an hour or two and remove most of the guesswork.
S50 and S52 maintenance and running costs
| Item | Recommendation |
|---|---|
| Engine oil | 10W-60 synthetic is common for S50 engines; 5W-30 Longlife for S52, about 5.5 to 6.5 litres. |
| Timing drive | Duplex and single timing chains at the front. |
| Service interval | Oil every 10,000 km; valve clearances for S50 every 30,000 km; VANOS service every 100,000 km. |
Fit a new oil pump nut and safety wire when the sump is off.
The single best thing you can do for an S50 and S52 is to change the oil more often than the longest factory interval. Clean oil protects bearings, chains, VANOS units and turbochargers, and costs far less than any of them.
Buying a used S50 and S52: the full checklist
Work through these points before you order a used S50 and S52, whoever you buy from.
- Confirm the exact engine code. Read the code stamped on the block and compare it with the code for your car. Send us the last seven characters of the VIN and we confirm the match before anything is paid.
- Ask how the donor car was damaged. Most good used engines come from cars with body damage. A front-end impact can crack sensors, the timing cover or the sump; a rear or side impact usually leaves the engine untouched. The yard records the damage on each unit.
- Compression or leak-down figures. Even compression across all cylinders tells you more than mileage. Ask for the figures, not just a pass or fail, and compare the highest and lowest readings: a spread above 10 to 15 percent deserves a question.
- Look at the oil and coolant. Clean oil without metal particles and coolant without oil are good signs. Milky oil, oily coolant or a burnt smell mean the engine needs further checks before it is fitted.
- Photographs from every side. Good suppliers photograph the actual engine you will receive. Look for the block stamp, the sump, the timing cover and any broken brackets or connectors in the pictures.
- List of what is fitted. Engines are sold with different ancillaries: some have the turbo, injectors, manifolds, alternator and starter, others are long blocks. Agree the list in writing so you know which parts must come from your old engine.
- Sump, oil pickup and drive variants. Rear-drive, xDrive and front-drive cars can use different sumps, oil pickups and engine mounts even with the same engine code. Check that the sump matches your subframe and front axle.
- Gearbox and flywheel match. Manual and automatic engines differ at the flywheel or flexplate, and sometimes at the crankshaft spigot. Make sure the engine you buy matches your gearbox or that you transfer the right parts.
- Warranty terms in writing. Read what the warranty covers, how long it runs and what fitting conditions apply. Most warranties require a qualified workshop, new fluids and filters, and replacement of the cooling parts that caused the original failure.
- Why your old engine failed. Before fitting a replacement, find out why the original failed. An overheating radiator, a blocked intercooler or a failed turbo can destroy a second engine if they are not fixed.
- Timing chain noise. Listen for a rattle at the front of the engine for the first seconds after a cold start. On an engine that cannot be run, look at the chain guides through the oil filler or with the valve cover off.
- VANOS operation. Rough idle, a rattle from the front of the head and a loss of torque at low revs point to VANOS seals or solenoids. These are serviceable parts and are easier to renew with the engine out.
- Bearing and valve clearance history. M engines are built to tighter tolerances. Ask for the last rod bearing replacement and valve clearance check, and consider an oil analysis if the engine can be run.
S50 and S52 prices: what you should pay
Our S50 and S52 stock runs to 80 units, priced from 3.246,00 € to 12.739,00 € with a median of 7.043,00 €.
Prices depend on the exact version, the donor's mileage, how complete the engine is and the demand for that code. Higher-output versions, low mileage and dressed engines with turbo, injectors and ancillaries cost more; long blocks and higher mileage cost less.
S50 and S52 prices by model year
| Model years | Units | From | Median | To |
|---|---|---|---|---|
| 1990–1994 | 29 | 5.369,00 € | 6.894,00 € | 7.896,00 € |
| 1995–1999 | 42 | 5.310,00 € | 7.306,00 € | 8.609,00 € |
Engines from 1990–1994 have a median of 6.894,00 €, while units from 1995–1999 sit at 7.306,00 €. Newer engines usually cost more because they come from younger donor cars with lower mileage and later updates.
S50 and S52 prices by mileage
| Donor mileage | Units | From | Median |
|---|---|---|---|
| under 50,000 km | 9 | 5.825,00 € | 7.101,00 € |
| 50,000 to 100,000 km | 24 | 5.628,00 € | 7.130,00 € |
| 100,000 to 150,000 km | 19 | 5.310,00 € | 6.829,00 € |
| over 150,000 km | 19 | 5.808,00 € | 7.056,00 € |
Mileage matters less than history on a well-maintained BMW engine, but it is a useful guide. A low-mileage unit from a younger car gives you more life for a modest premium.

Fitting a replacement S50 and S52
These are the steps we recommend to every workshop fitting one of our S50 and S52 engines.
- Compare the engines side by side. Put the replacement next to the old engine and compare sensors, brackets, connectors, the sump, the starter and the flywheel or flexplate. Note anything that must be transferred.
- Transfer the parts that differ. Move the parts that are specific to your car, such as the engine harness on some models, the sump on xDrive cars or the air conditioning compressor bracket. Use new seals and gaskets for everything you move.
- Replace the rear main seal and drive parts. With the engine out, the rear crankshaft seal is easy to reach. Fit a new one, inspect the flywheel and clutch on manual cars or the converter seal on automatics.
- Renew the cooling system. Most engine failures start with cooling. Fit a new water pump, thermostat and hoses, check the radiator and fan, and use the correct coolant.
- Fit new engine mounts. Old mounts transfer vibration and can let the engine move enough to damage hoses. They are cheap and easy to replace with the engine out.
- Inspect or replace the timing chain parts. Look at the guides and tensioner. On high-mileage engines, replacing them now costs far less than doing it later.
- Clean the intake. If the old engine failed internally, debris can be in the intake or intercooler. Clean them so nothing reaches the new engine.
- Fill with the right oil and prime it. Fill with new oil of the correct specification and a new filter. Crank with the fuel and ignition disabled until oil pressure builds.
- Coding and adaptations. On modern BMWs, the engine ECU must be matched to the car's immobiliser (CAS, FEM or BDC). Reset adaptations, register the battery and clear faults with diagnostic software.
- Reset VANOS adaptations. Clear the VANOS adaptations so the ECU learns the camshaft positions of the new engine.
- First start and leak check. Start the engine, let it idle and watch oil pressure, temperature and fault codes. Check for leaks and bleed the cooling system.
- First 1,000 km. Drive gently for the first few hundred kilometres, vary the engine speed and avoid full load. Change the oil and filter after about 1,000 km to remove any assembly debris.
Tuning and upgrades
S52 owners often fit a Schrick camshaft and an S50 manifold. Many E30 builds use an S52 for its torque and simplicity.
Whatever you plan, start with a healthy engine: a compression test, fresh fluids and the known weak parts replaced. Power upgrades amplify any existing problem.

What is the BMW S50B32 engine?
The BMW S50B32 is a 3.2 liter (3,201 cc) petrol engine from the S50 family. It has an inline 6, DOHC, 24 valve layout with no turbo (naturally aspirated), and makes 236 kW (321 HP) with 350 Nm of torque. BMW built it from 1995 to 1999 and it meets the Euro 2 emission standard.
You find the S50B32 in the BMW E36 M3, BMW E36 M3 Coupe and BMW E36 M3 Sedan. What we list: BMW S50 engines from the E36 M3.
At Autowerke Engines every S50B32 is a real used engine from our yard in Hamburg. The photos on each listing show the actual engine, not a stock picture. The yard checks the code, records what is bolted on, and seals the openings before the engine is offered. Each listing shows the year, the mileage and the price, so you can compare units side by side.

How much does a used BMW S50B32 engine cost?
A used BMW S50B32 engine in our yard usually costs between 5.850 € and 8.950 €. The exact price depends on the year, the mileage and the parts that come with the engine.
Our units show recorded mileage from about 22,000 km up to around 200,000 km. Lower mileage and more ancillaries mean a higher price. Each listing shows its own price, and the price you see is the price you pay. Prices include VAT for private buyers.
Shipping is a flat 249 € per order. It is added once at checkout and printed on the invoice, so there is no extra fee later. If you order a gearbox or a second engine on the same order, the fee is still charged once.

Which cars use the BMW S50B32 engine?
BMW fitted the S50B32 to the BMW E36 M3, BMW E36 M3 Coupe and BMW E36 M3 Sedan. These cars were built with this engine from about 1995 to 1999.
The badge on the boot is not enough to be sure. The same model name can hide two different engines, for example after a facelift or a change in emission rules. Always read the engine code stamped on the block, or look it up with your VIN.
Other engines in the same S50 family are the S50B30 (286 HP). They look alike but differ in power, parts and electronics, so they are not always a direct swap.

How much power and torque does the BMW S50B32 have?
From the factory the BMW S50B32 makes 236 kW (321 HP) and 350 Nm of torque. It is a 3.2 liter (3,201 cc) inline 6, DOHC, 24 valve petrol engine with no turbo (naturally aspirated).
Without a turbo, the power builds smoothly with the revs. A clean air intake, healthy ignition and the correct fuel are key to getting the full figure.
A used engine reaches its factory numbers when it is fitted with the matching engine computer and software, and serviced with the right oil and filters. If the engine computer from your car is a different version, a specialist may need to code it.
Every S50B32 on our site lists its year and mileage. Ask the desk for more pictures of any listing. We are happy to show the stamp, the ports and the ancillaries before you decide.

How do I know a used S50B32 engine is in good shape?
Each engine in the yard is inspected in Hamburg. The code is matched to the listing, the parts on the engine are recorded, the openings are sealed and the real unit is photographed. An inspection certificate for the unit can travel with the order when you ask for it.
When you look at a listing, check the recorded mileage, the year and the photos of the ports and the stamp. Ask for photos of anything you want to see closer. You can ask for extra photos, a close-up of the code stamp or a short video before you order.
On a petrol engine like the S50B32, a careful fitter will also look at the spark plugs, the coils and the timing side before the engine goes in.
If the engine fails inside under normal use, the warranty covers you. Eligible engines come with a 12 months warranty from the delivery date. It covers internal mechanical failure under normal use and correct fitting by a qualified mechanic or workshop.

What comes with a used S50B32 engine?
Each S50B32 is sold as described on its own listing. The yard writes down the parts that are fitted to that unit, such as the turbo, the injectors, the manifolds or the alternator, so you know what arrives.
Some units are long engines with few ancillaries, others are more complete. If you need a part that is not listed, ask the desk. We often have the matching items in the yard.
Every engine is drained, sealed at each opening, strapped to a heat-treated pallet and shrink-wrapped, then photographed before it leaves the yard.
On delivery, the carrier brings the pallet to the kerb or a loading bay. Please have a forklift, a pallet truck or an engine crane ready.

Is the BMW S50B32 a diesel or petrol engine?
The S50B32 is a petrol engine. It is a 3.2 liter (3,201 cc) inline 6, DOHC, 24 valve unit with no turbo (naturally aspirated), and it was built to the Euro 2 emission standard.
The emission standard matters for registration and for low-emission zones in many cities. When you replace an engine with the same code, the car keeps the same paperwork and the same emission class.
Petrol versions need the correct catalytic converters and oxygen sensors on the car to stay legal and to keep the engine computer happy. Reuse the parts from your car if they are in good condition.
If you are not sure which version you need, send us your VIN. We tell you the right code for free.

What is the difference between the S50B32 and other S50 engines?
The S50B32 makes 236 kW (321 HP) and 350 Nm. The other S50 engines are: S50B30 with 210 kW (286 HP) and 320 Nm (1992 to 1995).
Engines in one family share a basic block, but the turbo, the injection, the sensors and the engine computer can differ. A higher power version often has different pistons, a bigger turbo or a different fuel system.
This is why we ask for the exact code. Fitting a different version can work, but the wiring, the software and sometimes the gearbox must be changed to match.
Not sure? Send us your VIN and your gearbox code. We match the engine family, the year window and the parts on the engine before anything is reserved, and the check is free.

What should I replace when I fit a used S50B32 engine?
A used engine lasts longest when it starts life in your car with fresh fluids and new seals. Fit a new oil filter and fresh oil of the grade BMW lists for this engine, and refill the coolant with the correct BMW antifreeze mix. Change the drive belt, the thermostat and the water pump seals if they look tired, because they are cheap while the engine is out. Use new gaskets for the exhaust manifold, the intake and the sump plug, and check every hose clip before the first start.
Look at the engine mounts and the clutch or the torque converter while the engine is out. Old mounts can crack a new engine's brackets, and a worn clutch is much easier to change now.
Before the first start, turn the engine over without fuel until the oil pressure light goes out. Then let it idle, check for leaks, and drive gently for the first few hundred kilometres.
The warranty asks for fitting by a qualified mechanic and the correct oil, coolant and filters. Keep your receipts in case you ever need to make a claim.

Does a used S50B32 engine come with a warranty?
Yes. Eligible engines come with a 12 months warranty from the delivery date. It covers internal mechanical failure under normal use and correct fitting by a qualified mechanic or workshop.
The warranty does not cover damage from wrong fitting, overheating, low oil, wrong fluids or fuel, engines that were opened or modified without our approval, or labour and towing costs.
To claim, send us your order number, a short description of the problem, photos or a video, and a mechanic's report if we ask for one. If the claim is approved, we repair, replace or refund the engine.
Keep the receipts for the fitting, the oil and the filters. They make any claim quick and simple.

What is the BMW S50B30 engine?
The BMW S50B30 is a 3.0 liter (2,990 cc) petrol engine from the S50 family. It has an inline 6, DOHC, 24 valve layout with no turbo (naturally aspirated), and makes 210 kW (286 HP) with 320 Nm of torque. BMW built it from 1992 to 1995 and it meets the Euro 1 emission standard.
You find the S50B30 in the BMW E36 M3 3.0 and BMW E36 M3 Coupe 3.0. What we list: BMW S50 engines from the E36 M3.
At Autowerke Engines every S50B30 is a real used engine from our yard in Hamburg. Each engine in the yard is inspected in Hamburg. The code is matched to the listing, the parts on the engine are recorded, the openings are sealed and the real unit is photographed. Each listing shows the year, the mileage and the price, so you can compare units side by side.
Not sure? Send us your VIN and your gearbox code. We match the engine family, the year window and the parts on the engine before anything is reserved, and the check is free.

How much does a used BMW S50B30 engine cost?
A used BMW S50B30 engine in our yard usually costs between 5.200 € and 7.950 €. The exact price depends on the year, the mileage and the parts that come with the engine.
Our units show recorded mileage from about 22,000 km up to around 200,000 km. Lower mileage and more ancillaries mean a higher price. Each listing shows its own price, and the price you see is the price you pay. Prices include VAT for private buyers.
Shipping is a flat 249 € per order. It is added once at checkout and printed on the invoice, so there is no extra fee later. If you order a gearbox or a second engine on the same order, the fee is still charged once.
Inside the EU there is no import duty. For the UK and other non-EU countries, import duty and local VAT are paid by the receiver, and we supply a commercial invoice.

Which cars use the BMW S50B30 engine?
BMW fitted the S50B30 to the BMW E36 M3 3.0 and BMW E36 M3 Coupe 3.0. These cars were built with this engine from about 1992 to 1995.
The badge on the boot is not enough to be sure. The same model name can hide two different engines, for example after a facelift or a change in emission rules. Always read the engine code stamped on the block, or look it up with your VIN.
Other engines in the same S50 family are the S50B32 (321 HP). They look alike but differ in power, parts and electronics, so they are not always a direct swap.
Not sure? Send us your VIN and your gearbox code. We match the engine family, the year window and the parts on the engine before anything is reserved, and the check is free.

How much power and torque does the BMW S50B30 have?
From the factory the BMW S50B30 makes 210 kW (286 HP) and 320 Nm of torque. It is a 3.0 liter (2,990 cc) inline 6, DOHC, 24 valve petrol engine with no turbo (naturally aspirated).
Without a turbo, the power builds smoothly with the revs. A clean air intake, healthy ignition and the correct fuel are key to getting the full figure.
A used engine reaches its factory numbers when it is fitted with the matching engine computer and software, and serviced with the right oil and filters. If the engine computer from your car is a different version, a specialist may need to code it.
Every S50B30 on our site lists its year and mileage. You can ask for extra photos, a close-up of the code stamp or a short video before you order.
See all S50 Engines · Search S50B30 in the shop
How do I know a used S50B30 engine is in good shape?
The photos on each listing show the actual engine, not a stock picture. The yard checks the code, records what is bolted on, and seals the openings before the engine is offered. An inspection certificate for the unit can travel with the order when you ask for it.
When you look at a listing, check the recorded mileage, the year and the photos of the ports and the stamp. Ask for photos of anything you want to see closer. Ask the desk for more pictures of any listing. We are happy to show the stamp, the ports and the ancillaries before you decide.
On a petrol engine like the S50B30, a careful fitter will also look at the spark plugs, the coils and the timing side before the engine goes in.
If the engine fails inside under normal use, the warranty covers you. Eligible engines come with a 12 months warranty from the delivery date. It covers internal mechanical failure under normal use and correct fitting by a qualified mechanic or workshop.

What comes with a used S50B30 engine?
Each S50B30 is sold as described on its own listing. The yard writes down the parts that are fitted to that unit, such as the turbo, the injectors, the manifolds or the alternator, so you know what arrives.
Some units are long engines with few ancillaries, others are more complete. If you need a part that is not listed, ask the desk. We often have the matching items in the yard.
Every engine is drained, sealed at each opening, strapped to a heat-treated pallet and shrink-wrapped, then photographed before it leaves the yard.
On delivery, the carrier brings the pallet to the kerb or a loading bay. Please have a forklift, a pallet truck or an engine crane ready.

Is the BMW S50B30 a diesel or petrol engine?
The S50B30 is a petrol engine. It is a 3.0 liter (2,990 cc) inline 6, DOHC, 24 valve unit with no turbo (naturally aspirated), and it was built to the Euro 1 emission standard.
The emission standard matters for registration and for low-emission zones in many cities. When you replace an engine with the same code, the car keeps the same paperwork and the same emission class.
Petrol versions need the correct catalytic converters and oxygen sensors on the car to stay legal and to keep the engine computer happy. Reuse the parts from your car if they are in good condition.
If you are not sure which version you need, send us your VIN. We tell you the right code for free.

What is the difference between the S50B30 and other S50 engines?
The S50B30 makes 210 kW (286 HP) and 320 Nm. The other S50 engines are: S50B32 with 236 kW (321 HP) and 350 Nm (1995 to 1999).
Engines in one family share a basic block, but the turbo, the injection, the sensors and the engine computer can differ. A higher power version often has different pistons, a bigger turbo or a different fuel system.
This is why we ask for the exact code. Fitting a different version can work, but the wiring, the software and sometimes the gearbox must be changed to match.
Not sure? Send us your VIN and your gearbox code. We match the engine family, the year window and the parts on the engine before anything is reserved, and the check is free.

What should I replace when I fit a used S50B30 engine?
A used engine lasts longest when it starts life in your car with fresh fluids and new seals. Check the spark plugs and the ignition coils, and make sure the fuel lines are clean and tight before you crank the engine. Fit a new oil filter and fresh oil of the grade BMW lists for this engine, and refill the coolant with the correct BMW antifreeze mix. Use new gaskets for the exhaust manifold, the intake and the sump plug, and check every hose clip before the first start.
Look at the engine mounts and the clutch or the torque converter while the engine is out. Old mounts can crack a new engine's brackets, and a worn clutch is much easier to change now.
Before the first start, turn the engine over without fuel until the oil pressure light goes out. Then let it idle, check for leaks, and drive gently for the first few hundred kilometres.
The warranty asks for fitting by a qualified mechanic and the correct oil, coolant and filters. Keep your receipts in case you ever need to make a claim.

Does a used S50B30 engine come with a warranty?
Yes. Eligible engines come with a 12 months warranty from the delivery date. It covers internal mechanical failure under normal use and correct fitting by a qualified mechanic or workshop.
The warranty does not cover damage from wrong fitting, overheating, low oil, wrong fluids or fuel, engines that were opened or modified without our approval, or labour and towing costs.
To claim, send us your order number, a short description of the problem, photos or a video, and a mechanic's report if we ask for one. If the claim is approved, we repair, replace or refund the engine.

What is the difference between the BMW S50 engines?
BMW S50 engines from the E36 M3. We list 2 versions: S50B32 (3.2 liter (3,201 cc), 236 kW (321 HP), 1995 to 1999); S50B30 (3.0 liter (2,990 cc), 210 kW (286 HP), 1992 to 1995).
The versions share the same basic design, but the power, the turbo or injection set-up, the electronics and the emission standard change. The right one for you is the one your car was built with.
The S50 family was used in chassis E36. Before a unit is listed, the yard checks the engine code against the listing, writes down the parts fitted to it, seals every opening and photographs the real engine you will receive.
Not sure? Send us your VIN and your gearbox code. We match the engine family, the year window and the parts on the engine before anything is reserved, and the check is free.
What should I check on a used BMW S50 engine?
Start with the basics: the engine code on the block, the recorded mileage and the photos. Make sure the code matches your car and the parts you need are on the unit.
On an S50 petrol engine, a fitter usually checks the spark plugs, the coils, the timing side and the oil seals. These parts are easy to check before fitting and easy to change if needed.
If you want more photos or a short video of a unit, ask the desk and we send them before you pay. An inspection certificate can travel with the order on request.
Once fitted, change the oil and filter early and drive gently at first. Report any problem right away so the warranty stays valid.

Our verdict
The S50 and S52 has a clear set of strengths and a known list of weak points. Check the code against your VIN, ask for compression figures and photographs, replace the known weak parts while the engine is out, and fit it with fresh fluids and filters. Do that and a used S50 and S52 will give years of service.
