Hi guys my L320 is having issues with drivers seat not adjusting and memory function not working, so I can adjust Mirrors manually of the button, steering wheel adjust works of the button, the lumber support adjusts and heated seat works, I've checked the 2 fuses and both OK. red light on M does not Illuminate, steering wheel auto adjust when turned on works and reverse mirror memory works


Could this be an issue with the module and any idea how to test?
