Known faults

1 important faults

The timing chain of the longitudinal V6 diesel runs at the back of the engine, on the gearbox side, so replacing it means taking out the engine or the gearbox. That alone makes it expensive, but the mechanism is the point: the chains stretch and the hydraulic tensioners lose their pressure. The first and only early sign is a 2 to 3 second metallic rattle audible on a cold start. If that is ignored, the chain jumps or breaks, and the engine is badly damaged inside. The same chain kit also drives the oil pump: if that seizes, the engine is left without lubrication.

What to check

  • Start it cold, in a quiet place, with the bonnet open: the rattle is audible in the first 2 to 3 seconds
  • Stand at the gearbox side of the engine: the noise comes from there, not from the front
  • Ask whether the chain and the tensioner were replaced, and ask for the invoice (it involves removing the engine)

  • 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.
