Before you buy this car
From the generation guide
- 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.
- Drive off slowly from a stop, then in stop-and-go traffic. Bad result: a delayed take-up, a rough engagement or a warning light.
- 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.
- Ask a BMW dealer to check open recall campaigns for this VIN. Bad result: an open airbag campaign on a 2020 build.
