3 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

N47 / N57 diesel: timing chain on the rear of the engine

critical

In these diesels BMW put the timing chain at the back of the engine, on the gearbox side. The chain, the guides and the tensioner wear early. The symptom is a metallic rattle on a cold start that quietens once warm.

Show the rest

The engine or the gearbox has to come out for the replacement, so the labour is a multiple of the parts cost. If the chain breaks or jumps, the engine is badly damaged inside, and the repair is an engine rebuild.

The problem is worst on engines built between March 2007 and March 2011, and the ones before early 2009 are the worst of all. The maker handled it under a service campaign in several European markets, but in the United Kingdom there was no formal recall. "It was never recalled" does not mean the chain is fine.

According to the German technical press the fault affects the whole N47 series and every power output, inspection is advised from 100,000 km, and factory revisions closed the matter around 2013, so cars built after 2013 are in a significantly better position. Stretching is typically preceded by a distinct rattle.

between 100,000 and 200,000 km

What to check

  • Insist on a cold start: the car should stand overnight, and the seller must not start it before you arrive
  • At the moment of starting, stand behind the engine (on the gearbox side) and listen to the first 3 to 5 seconds
  • A metallic rattle from the back of the engine calls for immediate expert inspection: this is not "diesel noise"

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

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
