4 important faults

Diesel high pressure pump: power loss and engine shutdown while driving

critical

The high pressure pump of these common rail diesels (Bosch CP4) can fail while driving. The characteristic course is not gradual: a "Drivetrain fault" message appears on the dash, and within a few seconds the power is gone, on the motorway too. Afterwards the engine often cranks but will not start.

Show the rest

What makes the repair expensive: once the inside of the pump wears, metal debris travels through the rail and contaminates the entire fuel system. At that point replacing the pump is not enough: the injectors, the rails, the tank and the lines go with it. That is the difference between a "pump replacement" and a "full system replacement" quote, that is what you should ask about.

The maker started a recall for this in the United States (NHTSA 21V586000, 2014 to 2018 328d / X5 xDrive35d / 535d / 740Ld / X3 xDrive28d). The same campaign did not run in Europe, even though the same pump works in the 320d/520d/X3 20d versions that are common right across Europe. The recall does not cover these cars.

between 79,000 and 248,000 km

What to check

  • Ask whether there has ever been a "Drivetrain fault" message or a loss of power while driving
  • Ask for the service history: if the high pressure pump was replaced, check whether the injectors and the lines were replaced with it. If not, the debris may still be in the system
  • After a cold start listen to the engine at idle: irregular running or smoke is suspect

Diesel EGR cooler: cracking, coolant in the intake, fire risk

critical

The internal fins of the exhaust gas recirculation cooler crack over time, and glycol coolant leaks into the intake, where it mixes with soot. The sticky mixture can ignite at high temperature: it can melt the plastic intake manifold and, in extreme cases, cause an engine bay fire.

Show the rest

The maker recalled the 2013 to 2018 four and six cylinder diesels, roughly 800,000 cars worldwide. The first repair attempt proved insufficient, and the leak returned in several cases: the cooler fitted since 2022, from a different supplier, is the valid fix.

So "the recall was carried out" is not enough on its own: you have to check when, and which repair was done. A first round repair does not by itself rule the problem out.

The early symptoms are white, sweet smelling exhaust smoke, slowly dropping coolant, and a rough idle.

It shows up on diesels built between 2013 and 2018. The earlier M57 is not covered by the recall.

between 108,000 and 222,000 km

What to check

  • Check the level in the expansion tank, and ask whether it has needed topping up
  • After a cold start watch the exhaust: persistent white smoke and a sweet smell mean the coolant is burning
  • Ask for the service book and find the EGR cooler recall entry: Check the date too

B47 diesel: the timing chain stretches on the early model years

critical

On the early model years the timing chain of the B47 stretches faster than intended. The chain tensioner compensates for the stretch for a while and then no longer can: the chain jumps, the valve timing goes off, and in a severe case engine damage follows. The first sign is a rattling, clacking noise on a cold start that goes quiet after one to three seconds. On the B47 the chain sits at the front of the engine, not at the rear as on its predecessor, the N47. The replacement is therefore considerably less, between 1,200 and 1,800 euro, against 2,000 to 2,500 euro on the N47; if the chain has already jumped, the repair can run up to 4,500 euro. The risk is highest on units built before the end of 2015, with a reported rate of 3 to 5 per cent. 2016 was better but cases remained, and between July and December 2016 an improved chain tensioner was phased in. After mid-2016 the problem is rare, below one per cent. The engine has been in almost every four-cylinder diesel BMW since 2014, from the 1 Series to the 5 Series and from the X1 to the X4. The build date therefore says more here than the model.

above 120,000 km1,200–4,500 EUR

What to check

  • Start the engine cold and listen for the rattling noise in the first seconds
  • Ask for the build date, because units built before the end of 2015 are the risky ones
  • Ask whether the chain or the tensioner has been replaced, and ask for the invoice

B47 / B57 diesel: particulate filter and turbo on short trips

critical

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
