Does anyone know if it is possible (and straightforward) to retrofit power seats into an F54 Clubman? I would very much like to add the standard power / memory seat, but didn't know if the wiring harness was there on all cars. Thanks!

 

Very unlikely. The cars have unique wiring harnesses and since the car was not built with them, the wiring will not be there. It is not as simple as adding power and ground. Plus, the mounts for the seats are different and the cars BDC (computer) will not recognize options it was not built with. Simply coding something is no guarantee that it will work. In the end, it would likely cost thousands of dollars with no guarantee that it would work at all and the power seats cannot be manually adjusted if they don’t work
after all that.
