EA189 TDI: EGR valve and particulate filter blocking

expensive

The EGR valve and its cooler block up with soot and oily deposits; the particulate filter cannot regenerate on short urban trips. The signs are reduced power, a warning light, and frequent regeneration. The software update after the diesel emissions affair made the EGR operate more often, which accelerated the phenomenon: the maker gave goodwill repairs in several cases.

between 140,000 and 160,000 km

What to check

  • Ask what kind of journeys the car did: a daily short urban run is the worst for the filter
  • With a code reader look at the stored faults (P0401/P0402, and P2002 for the filter)
  • Ask whether it received the post emissions affair software update, and when

Dual mass flywheel: diesel

expensive

The internal springs of the flywheel tire, and the two discs knock against each other. The signs are a rattling or knocking from the bellhousing at idle and when releasing the clutch pedal, and vibration through the floor. If the clutch slips without a burnt smell, that also points to the flywheel. It is worth replacing in time: a disintegrated flywheel can destroy the bellhousing too. At a clutch replacement the two go together anyway.

What to check

  • At idle, without touching the clutch pedal, listen for the rattle from the bellhousing, then press the pedal: if it stops, that is suspect
  • Watch for the characteristic clatter on starting and switching off
  • Put your foot on the floor at idle: a noticeable vibration indicates tired springs

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.
