Reference Illustration

Symptoms

Rough vibration at idle
'Clattering' noise from bellhousing that disappears when clutch is pressed
Judder when slipping the clutch in 1st gear

Root Cause

Internal springs in the DMF weaken and break over time. High torque at low RPM accelerates this wear.

How To Fix

Replace DMF and Clutch as a full kit
Use LuK or Sachs components
Do not fit a solid mass conversion on the 6-speed box as it can damage the gearbox input shaft over time
Cost: £700-1,000

Other Faults on This Variant

High Pressure Fuel Pump Cam Follower Wear

Critical

2003-201320,000–100,000 miles£15–£1500

The same critical cam follower issue as the Golf Mk5 — the HPFP cam follower wears through to the camshaft. A £15 inspection and part replacement prevents a £2,500 camshaft repair.

Porous Cylinder Head (BKD Engine)

Critical

2003-200850,000–120,000 miles£1200–£2000

Early 2.0 TDI 140bhp engines (engine code BKD) suffered from porous cylinder heads, causing coolant to leak directly into the combustion chambers or oil ways.

Oil Pump Balancer Shaft Failure

Critical

2005-200880,000–150,000 miles£300–£2000

Some 2.0 TDI PD engines suffer from a catastrophic failure of the oil pump hex drive, leading to immediate oil starvation and engine destruction.
