2 important faults

critical1

The B47 replaced the N47, and the maker fixed the timing chain problem. The two remaining risks on this modern diesel depend on how the car was used.

Show the rest

The first is the particulate filter. On short urban trips the regeneration cannot finish, and the filter clogs. The second is the turbo. With extended oil change intervals its bearings wear.

On this engine the service history and the type of use tell you more than the odometer. On a 200,000 km car driven on motorways and serviced often, the filter and the turbo can be in better shape than on a 90,000 km city-only car.

Where turbo wear leads in the worst case: a runaway engine. If the turbo shaft seal fails, engine oil enters the intake on the compressor side. A diesel burns that too, and this is different from a petrol engine: a diesel controls torque with the quantity of fuel injected, and it has no throttle. Once the engine runs on its own oil, cutting the injection and switching off the ignition will not stop it. The revs climb on their own until the engine destroys itself for lack of lubrication.

If this happens while driving, turning the key does not help. The only thing that works is cutting off the air: cover or plug the intake, or discharge a dry powder extinguisher into the intake tract. On a manual car you can also stall it: hold the parking brake and the brake pedal, select a high gear, and release the clutch quickly so the drivetrain chokes the engine.

This is not common, and it can happen on any turbo diesel, not only on this engine. On this engine the turbo bearing and seal wear. The warning signs are blue smoke under acceleration, an unexplained drop in oil level, and an oily charge air pipe.

What to check

  • Ask how the car was used: short daily trips or longer runs?
  • Read the fault codes for particulate filter regeneration and differential pressure
  • On a longer test drive watch the power delivery and the smoke under load

The ZF eight speed automatic (BMW Steptronic 8HP family) has two faults, and you can feel both.

Show the rest

The first is the mechatronics unit: the valve body and the control electronics in one. If the solenoids or the pressure regulation weaken, the gearbox jerks, the D/R engagement is delayed, it logs a gear ratio fault code, and finally drops into limp mode (often staying in 2nd or 3rd).

The second, and often misdiagnosed, is the connector sleeve of the mechatronics unit: the O-ring of the plastic sleeve ages, and ATF leaks from the side of the housing, exactly where the wiring harness enters. This is easy to mistake for a rear crankshaft seal. The trail starts from the driver's side of the housing, not from the clutch side.

On cars built in 2023 there was also a separate safety recall for a welding fault in the mechatronics unit. That is not the same as the wear related sleeve and the valves.

Check the fluid level, the area around the sleeve and the fault codes first; do not accept a "full gearbox replacement" quote straight away.

above 120,000 km

What to check

  • On the test drive watch for delayed D/R engagement, a jerk when shifting, and limp mode (a stuck gear)
  • Look at the driver's side of the gearbox housing where the wiring harness enters: an ATF trail from the sleeve is suspect
  • Do not confuse it with a rear crankshaft seal leak: the direction of the trail decides
