The M70 and M73 are BMW's first V12s. The 5.0 litre M70 powered the E32 750i and the E31 850i from 1987. The 5.4 litre M73 followed in 1994 for the E38 750i and E31 850Ci, and it also powered the Rolls-Royce Silver Seraph.
They are smooth, quiet and refined, but complex and expensive to repair. Buyers are usually restorers of E31 8 Series and E32 or E38 7 Series cars.

History of the M70 and M73
BMW launched the M70 in 1987, effectively two M20 sixes joined on a common crank, with two separate engine management systems. The M73 of 1994 increased capacity and torque, and the M73TU of 1998 added further refinements.
1987: the M70B50 arrived with 5.0 L and 300 hp in the BMW E32 750i and BMW E31 850i.
1994: the M73B54 arrived with 5.4 L and 326 hp in the BMW E38 750i and BMW E31 850Ci. Compared with the M70B50, it added 26 hp.
1998: the M73TUB54 arrived with 5.4 L and 326 hp in the BMW E38 750i and BMW E38 750iL. It matched the M73B54 for power.
Every M70 and M73 version explained
M70B50 (5.0 L, 300 hp)
The M70B50 is a 5.0 L V12 petrol engine, naturally aspirated, rated at 300 hp and 450 Nm. BMW built it from 1987 to 1994. That is about 60 hp and 90 Nm per litre, a relaxed tune aimed at torque, durability and economy. Within the M70 and M73 family, the M73B54 (326 hp) and M73TUB54 (326 hp) are more powerful. It was fitted to the BMW E32 750i and BMW E31 850i.
Reading the code: M marks an M-series code, the naming BMW used for its engine families up to the early 2000s; 70 is the family number; B stands for petrol (from the German Benzin); 50 is the capacity in decilitres, so 5.0 litres.
M73B54 (5.4 L, 326 hp)
The M73B54 is a 5.4 L V12 petrol engine, naturally aspirated, rated at 326 hp and 490 Nm. BMW built it from 1994 to 2001. That is about 60 hp and 91 Nm per litre, a relaxed tune aimed at torque, durability and economy. Within the M70 and M73 family, it is the most powerful version, while the M70B50 (300 hp) is milder. It was fitted to the BMW E38 750i and BMW E31 850Ci.
Reading the code: M marks an M-series code, the naming BMW used for its engine families up to the early 2000s; 73 is the family number; B stands for petrol (from the German Benzin); 54 is the capacity in decilitres, so 5.4 litres.
M73TUB54 (5.4 L, 326 hp)
Built from 1998 to 2001, the M73TUB54 displaces 5.4 L in a V12 layout and is naturally aspirated. It produces 326 hp and 490 Nm on petrol. That is about 60 hp and 91 Nm per litre, a relaxed tune aimed at torque, durability and economy. Within the M70 and M73 family, it is the most powerful version, while the M70B50 (300 hp) is milder. It was fitted to the BMW E38 750i and BMW E38 750iL.
Which cars use the M70 and M73
The M70 and M73 was fitted to 5 models. The list below is grouped by chassis generation so you can find your car quickly. Always confirm the exact code with your VIN, because BMW often used more than one engine in the same model.
BMW E32 second 7 Series (1986–1994)
In the second 7 Series, built 1986–1994 as a saloon, the M70 and M73 powered the 750i (M70B50, 300 hp).

Will an M70 and M73 fit my BMW? Model-by-model answers
Short answers for every model that left the factory with an M70 and M73, with prices from our current stock.
Will the M73TUB54 fit my BMW E38 750i?
The M73TUB54 is the original engine for the BMW E38 750i, which makes it the straightforward choice. The third 7 Series was built 1994–2001, and the M73TUB54 was produced 1998–2001, so check that your car's build date falls inside that window. Confirm the drive type (rear-drive or xDrive), the gearbox (manual or automatic) and the emissions standard, because these can change the sump, the flywheel and the software. Send us the VIN and we check all of it for you.
How much is a replacement engine for a BMW E38 750i?
We do not have an M73TUB54 on the shelf for the E38 750i at the moment. Units arrive regularly; send us your VIN and we will tell you when the next one is ready and what it will cost, including delivery.
Will the M73TUB54 fit my BMW E38 750iL?
Yes, the BMW E38 750iL left the factory with the M73TUB54, so an M73TUB54 from another car is the direct replacement. The third 7 Series was built 1994–2001, and the M73TUB54 was produced 1998–2001, so check that your car's build date falls inside that window. Confirm the drive type (rear-drive or xDrive), the gearbox (manual or automatic) and the emissions standard, because these can change the sump, the flywheel and the software. Send us the VIN and we check all of it for you.

Common M70 and M73 problems and what to check
No engine is perfect. These are the faults our workshop sees most often on the M70 and M73, what causes them and how to check a used unit before you buy.
Wiring harness
Harness insulation becomes brittle with heat and age.
How to check: Inspect the harness near the heads.
Cooling
Radiators, hoses and fan clutches fail with age.
How to check: Pressure-test the system.
Dual engine management
A fault on one bank's management system causes rough running.
How to check: Read both ECUs for fault codes.
Fuel system
Fuel pumps, pressure regulators and injectors age.
How to check: Check fuel pressure.
Diagnosing a failing M70 and M73: 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 M70 and M73 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. |
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.
Repair or replace your M70 and M73?
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 M70 and M73 are damaged, a used engine is usually cheaper and quicker than a rebuild.
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.
M70 and M73 maintenance and running costs
| Item | Recommendation |
|---|---|
| Engine oil | 5W-40 or 10W-40 synthetic, about 7.5 litres. |
| Timing drive | Single-row timing chains, one per bank. |
| Service interval | Oil every 10,000 km or yearly. |
Keep the cooling system fresh. Check both ECUs before purchase.
Shorter oil intervals than the factory maximum are the cheapest insurance for an M70 and M73. Most of the expensive faults on BMW engines start with tired oil.
Buying a used M70 and M73: the full checklist
Work through these points before you order a used M70 and M73, 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.
- Originality and numbers. For collectible cars, the engine number and correct ancillaries add value. Photograph the stamp and keep it with the car's documents.
- Both cylinder banks and both ECUs. V12 engines often use separate management for each bank. Read faults from both and compare compression across all twelve cylinders.

Fitting a replacement M70 and M73
These are the steps we recommend to every workshop fitting one of our M70 and M73 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.
- 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
Few tuning options exist. Owners keep the V12 standard.
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.

How much does a used BMW M70B50 engine cost?
A used BMW M70B50 engine in our yard usually costs between 3.850 € and 5.950 €. 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 M70B50 engine?
BMW fitted the M70B50 to the BMW E32 750i and BMW E31 850i. These cars were built with this engine from about 1987 to 1994.
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.
The M70B50 is the only M70 version we list, which makes it easy to pick, but the wiring and the engine computer still need to match your car.

How much power and torque does the BMW M70B50 have?
From the factory the BMW M70B50 makes 220 kW (300 HP) and 450 Nm of torque. It is a 5.0 liter (4,988 cc) V12, SOHC, 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 M70B50 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 M70B50 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 M70B50, 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 M70B50 engine?
Each M70B50 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 M70B50 a diesel or petrol engine?
The M70B50 is a petrol engine. It is a 5.0 liter (4,988 cc) V12, SOHC, 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.

Are there other versions of the BMW M70B50?
In our yard the M70B50 is the only listed version of the M70 family. It makes 220 kW (300 HP) and 450 Nm, and was built from 1987 to 1994.
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 M70B50 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. Check the spark plugs and the ignition coils, and make sure the fuel lines are clean and tight before you crank the engine. Change the drive belt, the thermostat and the water pump seals if they look tired, because they are cheap while the engine is out.
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.

Our verdict
The M70 and M73 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 M70 and M73 will give years of service.
