Question 1

Clogged EGR valve (1.7 CRDi)

Accepted Answer

Carbon build-up in the EGR valve and inlet manifold on the 1.7 CRDi causes hesitation, rough idle, black smoke, an engine management light and limp mode. It is made worse by short journeys and long periods of idling.

Question 2

Dual-mass flywheel and clutch wear (1.7 CRDi)

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 (1.7 CRDi)

Accepted Answer

The diesel particulate filter on the 1.7 CRDi 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.
