Before you buy this car
From the generation guide
- 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
- Turbo (needs a scanner). Read boost faults and check the vanes. Bad: power loss, whistle or smoke.
- DPF (needs a scanner). Read soot and ash loading. Bad: frequent regeneration or high oil level.
- Intake manifold (pressure test). Pressure-test the cooling system. Bad: coolant loss with no puddle, worse under load.
- EGR cooler (pressure test). Cap the cooler hoses and repeat the test. Bad: it holds only with the cooler bypassed.
- AdBlue and NOx (needs a scanner). Read NOx sensor and dosing faults. Bad: an emissions warning, a restart countdown or crystallised AdBlue.
- Water pump and heater. Start cold; heater must blow hot. Bad: weak heat, wandering gauge, dried coolant.
- Oil pump drive (needs a scanner). Listen for a rattle at idle and check for oil-pressure codes. Bad: a red oil-pressure warning.
- Belt and pump invoices. Ask for dated belt, pump and thermostat invoices. No record means budget for a belt job.
- Recall check. Enter the VIN in the official recall check. Bad: an open 23Z7 campaign on a T6.
