The Mk5 GTI (2006–2009) is where the modern GTI came right — the 2.0 FSI turbo, the DSG option, a great chassis. Buy on the known FSI items.
Mk5-specific checks:
- Cam follower — the single most important check; a worn one wrecks the cam and HPFP (FSI Cam Follower HPFP). Ask when it was last done; fit the updated one.
- Carbon build-up on the intake valves — a walnut blast is due by now (FSI Carbon Buildup).
- HPFP (HPFP Failure), PCV (EA888 PCV Breather), diverter valve (Diverter Valve), and P2015 intake flaps (Imrc Intake Flap).
DSG: confirm the service history (~40k fluid) — a neglected mechatronic is expensive (DSG Mechatronic Service).
