Question 1

Dual-mass flywheel and clutch wear (2.0 TDI)

Accepted Answer

Judder when pulling away, a rattle at idle that stops when the clutch pedal is pressed and vibration through the pedal point to a worn dual-mass flywheel. It is common on diesel cars driven in stop-start traffic and is normally replaced together with the clutch.

Question 2

DPF blockage from short journeys (2.0 TDI)

Accepted Answer

The diesel particulate filter on the 2.0 TDI needs regular sustained runs at motorway speeds to regenerate. Cars used mainly for short urban trips light up the DPF warning, lose power and may go into limp mode; repeated interrupted regenerations also dilute the engine oil with diesel.

Question 3

EGR cooler coolant leak (2.0 TDI)

Accepted Answer

The EGR cooler on the 2.0 TDI can crack internally, so coolant is lost with no visible external leak. Symptoms include a slowly dropping coolant level, white smoke or a sweet smell from the exhaust and, in advanced cases, overheating. Some cars were covered by a manufacturer recall or extended warranty.
