OBD Codes

None

Symptoms

Grinding or crunching noise when operating the window switch

Other Faults on This Variant

High Pressure Fuel Pump Cam Follower Wear

Critical

2004-200920,000–100,000 miles£15–£1500

The PD (pumpe-düse) 2.0 TDI uses a mechanical cam follower to drive the high-pressure fuel pump. This follower wears rapidly and if not replaced destroys the camshaft — a £2,500 repair for a £15 part.

Dual Mass Flywheel Failure

Severe

2004-200980,000–160,000 miles£700–£1200

DMF failure on the Golf Mk5 2.0 TDI is a rite of passage for high-mileage cars. The flywheel absorbs diesel engine vibrations but wears out — often needing clutch replacement at the same time.

Gearbox Dogbone Mount Bush Failure

Minor

2004-200970,000–140,000 miles£50–£150

The lower engine pendulum mount (often called the dogbone mount) bushes perish, causing excessive engine movement, clunking, and sloppy gear changes.
