Before you buy this car
From the generation guide
- Check the oil level when the engine is cold. Ask for the top-up record with dates and kilometres. A car that needs regular top-ups between services is a warning sign.
- Drive over a rough road and listen for knocks from the front and rear axle. Ask for alignment and suspension work records. Inspectors often flag suspension mounts at the German HU (the statutory inspection).
- Pair a phone over Bluetooth and start Apple CarPlay during the test drive. A failed pairing or CarPlay that will not start is a warning sign. A fault memory read needs a scanner.
From the engine guide
- Coolant and water pump (scanner). Check the coolant level when cold. Look for a puddle under the front centre of the car. Read the stored faults for P00B7 (low coolant flow). Ask for an invoice showing the pump and housing were replaced as one assembly. Bad: low coolant, P00B7, or overheating. A missed leak can wreck the engine: 4,000-15,000 GBP for major damage (UK, 2025).
- Turbo and wastegate (test drive, scanner). Check that boost builds smoothly with no hesitation and no warning light. Ask for turbo or actuator invoices. Bad: boost loss, a warning light, or a turbo replaced with no paperwork.
- Oil in the intake (scanner). Ask whether the car was driven hard or on track. Check for a rough idle, a check-engine light, and oil in the intake. Bad: any of these, or a track history with no service record.
- Oil leaks at the back of the engine (no scanner). Look under the engine and where it meets the gearbox. Bad: oil at the rear seal. The fix needs the gearbox separated from the engine, so the job is large.
