Question 1

Leaking injector seals (1.6 TDCi)

Accepted Answer

Failed injector copper washers let combustion gases escape, producing a chuffing noise, a smell of diesel fumes in the cabin and black carbon deposits ('black death') around the injectors. Left alone, the injectors seize in the head and become very hard to remove.

Question 2

Dual-mass flywheel and clutch wear (1.6 TDCi)

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 (1.6 TDCi)

Accepted Answer

The diesel particulate filter on the 1.6 TDCi 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.
