Known issues for this car

Before you buy this car

From the generation guide

1. Read the steering warning lamp and stored codes with a scanner. Bad result: a warning lamp, a pull or drift, or no repair record for the sensor or steering software.
2. Check the iDrive screen, Bluetooth and navigation for ten minutes. Bad result: freezes, dropouts, dead pixels or an old software version.
3. Lift the car and check the front shocks, ball joints and stabiliser links. Bad result: play in the joints, leaking shocks or knocks over bumps.
4. On a pre-facelift rear-wheel-drive car, ask for proof that the steering gear bolts were replaced with steel. Bad result: no record.

From the engine guide

1. EGR recall (VIN check). Check the VIN for open BMW campaigns. Ask for proof that the EGR cooler was checked or replaced. Bad: an open EGR campaign, or no proof on a car built 2014-2020.
2. Turbocharger (test drive). Ask where the car was driven. Turbo damage is reported mostly on cars used in low outside temperatures, where moisture in the clean-air pipe can freeze. Ask for turbo invoices. Bad: a turbo job with no paperwork. No scanner needed.
3. Injectors (records). Ask for injector service records on any car above 150,000 km. Bad: no record at that mileage. No scanner needed.
4. DPF (scanner). On any car above 250,000 km, check for DPF cleaning or replacement records. Bad: no records. A scanner shows stored DPF fault codes.
5. EGR valve (records). Ask whether the EGR valve was cleaned or replaced. Bad: a car used mostly in heavy traffic with no record. No scanner needed.
