740d engines by model year
| Model year | Engine |
|---|---|
| 1999 | M67D40 (245 hp), M67D44 (330 hp) |
| 2000 | M67D40 (245 hp), M67D44 (330 hp) |
| 2001 | M67D40 (245 hp), M67D44 (330 hp) |
The 740d kept the same engine for the whole E38 run, which makes ordering simple: any unit with the same code fits, subject to the gearbox, drive type and sump.
Other cars with the same engine as the 740d
A replacement engine does not have to come from another 740d. 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.
M67D40: BMW E38 740d L.
M67D44: BMW E65 745d.
How to confirm your engine code
Because the 740d 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 740d engine problems
The M67D40 and M67D44 in the 740d share the known weak points of the M67 family. Full M67 guide.
| Known fault | What to check |
|---|---|
| Turbochargers | Check shaft play and smoke. |
| Injectors | Read injector correction values. |
| Glow plugs and wiring | Check the glow system. |
Turbochargers. Turbos wear and leak oil.
Injectors. Injectors fail.
Glow plugs and wiring. Glow plugs and wiring age.
Symptoms to watch for on the 740d
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.
Looking after the 740d engine
- Oil: 5W-30 BMW Longlife-04.
- Service interval: Oil every 10,000 km.
- Timing drive: Timing chains.
- Workshop notes: Ask for service history.
Buying a used engine for the 740d: checklist
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Both cylinder banks. On a V engine, check compression, plugs and coils on both banks. Faults on one bank alone are common and easy to miss on a quick test.
BMW 740d replacement engine cost
We do not have a 740d engine on the shelf at the moment. Send us your VIN or the code you need and the desk will tell you when the next unit arrives and what it will cost.
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 740d?
Will the M67D40 fit my BMW E38 740d?
Yes, the BMW E38 740d left the factory with the M67D40, so an M67D40 from another car is the direct replacement. The third 7 Series was built 1994–2001, and the M67D40 was produced 1999–2001, 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 740d?
We do not have an M67D40 on the shelf for the E38 740d 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 M67D44 fit my BMW E38 740d?
The M67D44 is the original engine for the BMW E38 740d, which makes it the straightforward choice. The third 7 Series was built 1994–2001, and the M67D44 was produced 1999–2009, so check that your car's build date falls inside that window.

Fitting a replacement engine in the 740d
- 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.
- 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.
- 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.
- 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.

740d engine questions
How much does a used BMW M67D44 engine cost?
A used BMW M67D44 engine in our yard usually costs between 3.350 € and 5.200 €. 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.

How much power and torque does the BMW M67D44 have?
From the factory the BMW M67D44 makes 242 kW (329 HP) and 750 Nm of torque. It is a 4.4 liter (4,423 cc) V8, DOHC, 32 valve diesel engine with twin turbochargers.
Because it is turbocharged, the torque comes in low in the rev range, which makes the car feel strong in everyday driving. A healthy turbo, a clean intercooler and tight boost pipes 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 M67D44 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.
