Known issues for this car

Before you buy this car

From the generation guide

1. Check the oil level after the test drive and ask for oil use records. Oil loss with no visible leak points to valve stem seals.
2. On an N46, N52 or N55 petrol, check the idle. A strongly hunting idle points to Valvetronic wear.
3. Lift the car and check the front control arms and rear bushings for play and cracks. Ask whether pothole damage was repaired.

From the gearbox guide

1. Read the fault memory with ISTA or a BMW or Audi scanner. Bad result: BMW codes 4F85, 4F8F or 4F83, or a past limp mode. A scanner is needed.
2. Ask for fluid and pan service records. Bad result: no change in the last 60,000 to 100,000 km, or no adaptation reset afterwards. Dirty oil adds to mechatronic wear.
3. Drive 15 minutes in town, then under load. Bad result: slipping, flaring, or jerks on 2-3 and 3-4.
4. Hold a steady light throttle at 60 to 80 km/h. Bad result: a shudder or vibration, which points to the torque converter lock-up clutch.
5. Drive under load in 4th and 5th. Bad result: slip under load or jerks on shift, which points to worn bushings.
