Known issues for this car

Before you buy this car

From the generation guide

1. 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.
2. 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).
3. 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 gearbox guide

1. Mechatronic scan (needs a scanner). Read the gearbox fault memory for P0718, P0811, P0607, P179B and P17D1. Bad result: stored faults or a recent limp mode.
2. Cold clutch test. Pull away uphill and reverse up a ramp, twice. Judder means clutch work.
3. Pump motor history (needs a scanner). Check for pump and circuit board faults. A failed motor can stop the car.
4. Speed sensor campaign. Ask a dealer for campaigns 34 22 54 and 34 23 62. Scan for P0718 and P2768.
5. Gear position sensor (needs a scanner). On cars up to 2018, check the key comes out in P and the display lights.
6. Oil leaks. Check the plastic pan, mechatronic and housing joint.
7. Oil records. Look for 60,000 km oil changes with G 055 529 A2. Stamps prove nothing.
