Which engine is in your 330d?

M57D30 in the 330d

The M57D30 was used in the E46 330d, built 1998–2005. It is a 3.0 L turbocharged diesel inline-6 with 184 hp and 390 Nm. Compared with the M57D30OL (184 hp) and M57D30TU (218 hp), it is in between.

Reading the code: M marks an M-series code, the naming BMW used for its engine families up to the early 2000s; 57 is the family number; D stands for diesel; 30 is the capacity in decilitres, so 3.0 litres.

M57D30OL in the 330d

The M57D30OL was used in the E46 330d, built 1998–2003. It is a 3.0 L turbocharged diesel inline-6 with 184 hp and 390 Nm. Compared with the M57D30 (184 hp) and M57D30TU (218 hp), it is in between.

Reading the code: M marks an M-series code, the naming BMW used for its engine families up to the early 2000s; 57 is the family number; D stands for diesel; 30 is the capacity in decilitres, so 3.0 litres; OL identifies the version or output stage.

M57D30TU in the 330d

The M57D30TU was used in the E46 330d, built 2002–2007. It is a 3.0 L turbocharged diesel inline-6 with 218 hp and 500 Nm. Compared with the M57D30 (184 hp) and M57D30OL (184 hp), it is the strongest.

Reading the code: M marks an M-series code, the naming BMW used for its engine families up to the early 2000s; 57 is the family number; D stands for diesel; 30 is the capacity in decilitres, so 3.0 litres; TU identifies the technical update.

330d engines by model year

The engine changed 3 times during the E46 run, in 2002, 2004 and 2006. Changes usually come with BMW's mid-life update (LCI) or a new emissions standard, so a car registered early in a year can still have the older engine. The VIN settles it.

Other cars with the same engine as the 330d

A replacement engine does not have to come from another 330d. These models left the factory with the same engine code, so a unit from any of them is a candidate donor once the sump, mounts and ancillaries are matched to your car.

M57D30: BMW E39 530d, BMW E53 X5 3.0d, BMW E38 730d.

M57D30OL: BMW E39 530d.

M57D30TU: BMW E60 530d, BMW E83 X3 3.0d, BMW E65 730d.

How to confirm your engine code

Because the 330d used more than one engine, the badge alone does not tell you which one your car has. The build date is the first clue; the VIN is the proof. Send us the last seven characters of the VIN and we read the engine code from BMW's records, or look for the code stamped on the block. How to find your BMW engine code.

Known 330d engine problems

The M57D30, M57D30OL and M57D30TU in the 330d share the known weak points of the M57 family. Full M57 guide.

Swirl flaps. The swirl flaps can loosen and break off, and a broken flap can enter a cylinder and destroy the engine.

EGR valve and cooler. The EGR valve clogs and the cooler can leak.

Injectors. Injectors leak or fail, especially piezo versions.

Turbocharger. Turbos wear and actuators stick.

Thermostat and viscous fan. Thermostats fail and cause slow warm-up.

Symptoms to watch for on the 330d

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.

Whistle, loss of boost or limp mode. A split charge pipe, a sticking wastegate or worn turbo bearings. Check the pipes first, then the turbo shaft for play.

Black smoke under acceleration. Too much fuel for the air available: boost leaks, a sticking EGR valve, a dirty air mass meter or a leaking injector.

Hard starting when cold. Glow plugs or the glow plug control unit. On older diesels, also check the injection pump and fuel lines for air leaks.

Sudden metallic noise followed by misfire. On diesels with swirl flaps, a broken flap or screw can enter a cylinder. Stop the engine immediately; continued running usually destroys the piston and head.

Looking after the 330d engine

• Oil: 5W-30 BMW Longlife-04, about 6.5 to 7.5 litres.
• Service interval: Oil every 10,000 to 15,000 km.
• Timing drive: Timing chain at the front.
• Workshop notes: Fit swirl flap blanks when installing a used M57. Conversions need the right sump and wiring.

Buying a used engine for the 330d: checklist

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Turbocharger shaft play and oil. Rotate the compressor wheel by hand. A small amount of side play is normal; in-and-out play or wheel contact with the housing is not. Oil pooled in the intake or intercooler pipes points to worn seals.
7. Injector correction values. On a diesel that can be run before removal, the injector correction values show whether one injector is delivering more or less fuel than the others. Large deviations mean an injector is on its way out.
8. Swirl flaps. Check whether the swirl flaps are in place, blanked or removed. Broken swirl flaps are a known cause of engine failure on several BMW diesels, so many owners fit blanking plates when the intake is off.
9. 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.

BMW 330d replacement engine cost

Our 330d engine stock runs to 249 units, priced from 376,00 € to 4.348,00 € with a median of 2.590,00 €.

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.

330d engine prices by model year

Engines from 2000–2004 have a median of 2.506,00 €, while units from 2020–2024 sit at 2.794,00 €. Newer engines usually cost more because they come from younger donor cars with lower mileage and later updates.

330d engine prices by mileage

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.

2 of these come from E46 donor cars, priced from 376,00 € to 1.320,00 €. An engine from the same body is the most direct swap because the sump, mounts and ancillaries already match.

On top of the engine, budget for the workshop's labour and the parts that are best replaced while the engine is out: engine mounts, the rear main seal, cooling parts, a clutch or converter seal, fluids and filters.

Will it fit my 330d?

Will the M57D30 fit my BMW E46 330d?

The M57D30 is the original engine for the BMW E46 330d, which makes it the straightforward choice. The fourth 3 Series was built 1997–2006, and the M57D30 was produced 1998–2005, 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 E46 330d?

We have 2 M57D30 engines from E46 donor cars, priced from 376,00 € to 1.320,00 €. Delivery to your door is included, and the engine carries a 12-month warranty when fitted by a qualified workshop. Add fitting labour and the parts you replace at the same time — seals, cooling parts and mounts — to estimate the total.

Will the M57D30OL fit my BMW E46 330d?

For the BMW E46 330d, the M57D30OL is the factory engine and the one to order. The fourth 3 Series was built 1997–2006, and the M57D30OL was produced 1998–2003, 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 E46 330d?

We have 1 M57D30OL engine from E46 donor cars, priced from 1.320,00 €. Delivery to your door is included, and the engine carries a 12-month warranty when fitted by a qualified workshop. Add fitting labour and the parts you replace at the same time — seals, cooling parts and mounts — to estimate the total.

Engine swaps and upgrades for the 330d

These engines were fitted to other versions of the E46 at the factory, which makes them the most practical upgrades: the body was designed around them and many parts are shared.

Can I fit the M54B30 in my 330d?

It is a full conversion: the M54B30 runs on petrol and the M57D30TU on diesel, so the fuel system, wiring, engine control unit, instrument coding and usually the gearbox change too. The gain is 13 hp and 0 Nm. In Germany and most of Europe an engine swap must be inspected and registered.

Can I fit the S54B32 in my 330d?

It is a full conversion: the S54B32 runs on petrol and the M57D30TU on diesel, so the fuel system, wiring, engine control unit, instrument coding and usually the gearbox change too. The gain is 125 hp and 0 Nm. In Germany and most of Europe an engine swap must be inspected and registered.

Fitting a replacement engine in the 330d

1. 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.
2. Prepare the turbo. Fit new oil feed and return seals, clean the intercooler and pipes of any oil or debris from the old engine, and prime the turbo with oil before starting.
3. Code the injectors and bleed the fuel. Enter the injector correction codes into the ECU, check the glow plugs and bleed the fuel system so the engine does not crank dry.
4. 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.
5. 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.
6. 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.
7. 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.

The full fitting and first-start procedure.

Is the BMW M57D30TU a diesel or petrol engine?

The M57D30TU is a diesel engine. It is a 3.0 liter (2,993 cc) inline 6, DOHC, 24 valve unit with a variable-geometry turbocharger, and it was built to the Euro 4 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.

Diesel versions need the matching exhaust treatment parts 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.
