This is not just a re-calibration issue - I’ve tried that and it doesn’t work. A scan shows that there’s an issue with the Hall effect sensor in the motor that controls the forwards and backwards position on the driver’s seat. I assume that this is also why the memory function on the driver’s seat doesn’t work. The seat moves in all directions but the car just can’t identify where it is. The motor sits in a bar under the seat. I’d sort of hoped that I could pick up a replacement but my local BMW dealer parts department inform me that it’s not available on it’s own, I need a complete electric seat base at over £700 plus VAT 😩 Has anyone ever encountered this issue before? Any advice or suggestions please? Is there any sort of workaround or is it feasible for the motor to be repaired? All help gratefully received.
