2 important faults

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"

XDrive transfer case (ATC): binding in corners, plastic actuator gear

expensive

The heart of the four wheel drive in the longitudinal engine BMW X models (X3, X5 and the X1 E84) is the ATC transfer case. It has two faults, and you can feel both while driving.

Show the rest

The first is wear of the clutch pack and the fluid: in a slow, tight corner (a car park, a roundabout) the car jerks and "hops", as if the drive grabbed and let go. You can also get a jerk when pulling away on a slope. The second is the plastic actuator gear: the position signal is lost, the brake, ABS and 4x4/DSC lights come on together on the dash, and a clicking is audible from the transfer case when you switch the ignition off.

Workshops often propose a full transfer case replacement straight away. But the plastic gear can be replaced on its own, and the wrong tyre size or a mixed set of tyres also imitates the jerking, because the transfer case then slips continuously. So clear up the tyres and the fault code first, before you pay for a transfer case replacement.

between 72,000 and 175,000 km

What to check

  • In a slow, tight corner (a car park) watch for jerking, binding and a "skipping" feel
  • When pulling away on light throttle, can you feel the drivetrain jerk
  • Watch the dash: 4x4, ABS, DSC and brake lights together point at the actuator

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • 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.
