sorted it was the relay dose help having another z3 parked on the drive. I checked some of the earths that could cause it and found that the power supply to the seat was shorting wet carpets again. So I have pulled all the fuses that are now not needed roof seats etc . going to use the live feed to the seat to feed my DRL vier a switch so I can turn them off. next job
