Question 1

Inlet swirl flap failure (2.0 CDTi)

Accepted Answer

The inlet swirl flaps and their actuator can stick or break, causing a loss of power, an engine warning and, in rare cases, debris entering the engine.

Question 2

Dual-mass flywheel and clutch wear (2.0 CDTi)

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 3

DPF blockage from short journeys (2.0 CDTi)

Accepted Answer

The diesel particulate filter on the 2.0 CDTi 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.
