Known issues for this car

Before you buy this car

From the generation guide

1. Lift the floor mats and press the carpet in both front footwells. Bad result: damp carpet, a musty smell, or rust on the floor.
2. Drive slowly and check the steering for stiffness, noise or play around the centre. A scanner reads the steering fault codes. Bad result: a steering warning lamp, a pull, or no record of steering work.
3. Lift the car and check the joints and shocks by hand. Bad result: play in the joints, leaking shocks or knocks over bumps.
4. Ask a BMW dealer to check open recall campaigns for the car's VIN. Bad result: an open campaign for the steering, starter, brake booster or seat backrest.

From the gearbox guide

1. Read the gearbox fault memory with a BMW-capable scanner. Bad result: pressure or solenoid codes such as 4F84, 4F87, P189C or P0748, or a past limp mode.
2. Ask for fluid and filter invoices. Bad result: no fluid change by 80,000 to 120,000 km, or a change without an adaptation reset.
3. Drive the car from cold and select Drive and Reverse. Bad result: a hard 1-2 shift, or a delay of 1-3 seconds before the gear engages.
4. Drive 15 minutes in town, then under load. Bad result: jerky 2-3 shifts, flaring, slipping or a burnt smell.
5. Hold a steady light throttle at low speed. Bad result: a shudder or vibration, which points to the torque converter lock-up clutch.
6. Look under the car on a lift. Bad result: oil at the wiring connector on the case, on the plastic pan or on the cooler lines.
