Known issues for this car

Before you buy this car

From the generation guide

1. Listen for a metallic rattle in the first seconds after a cold start. A BMW-capable scanner reads codes P0008, P0016, P0017 and P0341. Bad result: a rattle, those codes, or no chain history after 100,000 km.
2. Open and close the rear doors and listen on a bumpy road. Bad result: a creak from the rear passenger area, or seals that come loose.
3. Ask a BMW dealer to check open recall campaigns for this VIN. Bad result: an open airbag campaign on a 2020 build.

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.
