EA888 gen3: crankcase ventilation, oil in the intake

expensive

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.

What to check

  • After a test drive under load, look at the exhaust: it should not smoke blue under hard braking after sustained acceleration
  • Ask about topping up between two oil changes: adding oil every 1,000 to 1,500 km is not normal
  • Look at the intake connections and the ventilation hose: oily deposits mean oil in the intake

TSI ignition coil: misfire, jerking, engine warning light

cheap repair

The per cylinder ignition coil of these direct injection, turbocharged petrol engines fails. According to the Haynes service material this and similar simple electrical faults account for roughly eighty per cent of workshop visits.

Show the rest

In cold, damp weather, on startup, the engine runs unevenly, misfires under acceleration, and the engine warning light flashes or stays on. Do not keep driving with the light flashing: the unburnt fuel destroys the catalytic converter.

What to check

  • Start with a cold engine and watch the first half minute: a rough idle or shaking is suspect
  • On the test drive load the engine at low revs with a lot of throttle: the misfire shows then
  • A flashing engine warning light calls for stopping immediately

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.
