REDLINE ALLEYVolkswagen Golf GTI Mk5 buying guide
2004 to 2009. A Mk5 GTI suits a buyer who wants a practical, quick hatch and checks the cam follower and cambelt records.
Big jobs
- High pressure fuel pump cam follower. The cam follower that drives the high pressure fuel pump can wear early, especially on long life serviced cars, and failure can cause serious top end damage.
- DSG mechatronic unit. A lurch when pulling away from a standstill points to a failing DSG mechatronic unit.
- Cambelt. The cambelt, water pump and tensioners need replacing on schedule.
Workshop jobs
- Oil use and valve carbon. Carbon builds up on the back of the inlet valves and oil use can rise. VW considers a litre every 1,000 miles normal.
- Rear dampers and tyre wear. Weak rear dampers wear the inner edges of the rear tyres and can cause a drone like a worn wheel bearing.
Small jobs
- Diverter valve. The rubber diaphragm in the diverter valve wears and lets boost escape, giving a flat spot and lost power.
- Coil packs. Coil packs are a regular failure point.
- Crankcase breather valve. A failing breather valve gives a poor idle and an air leak sound when the engine is switched off.
Questions for the seller
- When was the cam follower last checked or replaced?
- When were the cambelt and water pump last done?
- Is it manual or DSG, and does the DSG lurch from rest?
- Has it been on fixed or long life servicing?
- Has it been remapped?
