The fault

How you spot it

The crankcase ventilation (PCV) of the third generation 1.8/2.0 TSI fails less often than its predecessors, but it is not faultless. After sustained full load acceleration, under hard braking, the return branch of the ventilation can be overloaded, and the oil ends up in the intake instead of draining. The symptoms are oil consumption, blue smoke after load, and deposits in the intake.

This also reinforces the other, already known phenomenon: because of the direct injection, the coke building up on the intake valves grows faster with oil reaching the intake.

How we know

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.
