Common N73B60 problems
The N73B60 shares its weak points with the rest of the N73 family. These are the faults to check on a used unit and on your own engine. The full explanation of each is in the N73 and N74 guide.
| Known fault | What to check |
|---|---|
| Ignition coils and spark plugs | Read misfire counters. |
| Injectors | Read injector corrections. |
| Coolant leaks | Pressure-test the system. |
| Turbo oil lines (N74) | Look for oil smoke. |
Coolant leaks. Coolant pipes and hoses leak because of heat in the V.

Will the N73B60 fit my car?
Will the N73B60 fit my BMW E66 760i?
Yes, the BMW E66 760i left the factory with the N73B60, so an N73B60 from another car is the direct replacement. The fourth 7 Series long-wheelbase was built 2001–2008, and the N73B60 was produced 2003–2008, 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.

Will the N73B60 fit my BMW E65 760Li?
For the BMW E65 760Li, the N73B60 is the factory engine and the one to order. The fourth 7 Series was built 2001–2008, and the N73B60 was produced 2003–2008, 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.

Buying a used N73B60: checklist
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Injectors and high-pressure fuel pump. Direct-injection engines rely on high-pressure pumps and precise injectors. Ask whether the injectors are original or updated and whether there were fuel pressure faults.
- 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.
Questions about the N73B60
What should I replace when I fit a used N73B60 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.

Are there other versions of the BMW N73B60?
In our yard the N73B60 is the only listed version of the N73 family. It makes 327 kW (445 HP) and 600 Nm, and was built from 2003 to 2008.
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.

Which cars use the BMW N73B60 engine?
BMW fitted the N73B60 to the BMW E65 760i and BMW E66 760Li. These cars were built with this engine from about 2003 to 2008.
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 N73B60 is the only N73 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 N73B60 have?
From the factory the BMW N73B60 makes 327 kW (445 HP) and 600 Nm of torque. It is a 6.0 liter (5,972 cc) V12, DOHC, 48 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 N73B60 on our site lists its year and mileage. If you want more photos or a short video of a unit, ask the desk and we send them before you pay.

Is the BMW N73B60 a diesel or petrol engine?
The N73B60 is a petrol engine. It is a 6.0 liter (5,972 cc) V12, DOHC, 48 valve unit with no turbo (naturally aspirated), 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.
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.
