[surrey 335i]

I need some coding help in the next few days anyone located Surrey/Middlesex/west London who can help?

Fitted set of leather seats to 2010 318i and the seats are from a Pre-LCi model this has triggered airbag and seatbelt warning lights.

Have fitted a bypass resister for active headrests suspect this is the wrong and is causing the warning lights.

thanks if you can suggest someone
