My 2012 Leon TDI has been parked up for some time now as it couldnt pass an MOT. The airbag light has been on it for quite a while and while trying to clear it, it would immediately come back on, knowing how to work on cars, I decided to change the whole module, as some reading devices have said its a faulty module.
Does anyone know where the location to the module is and if i get a new one with the same part number, is it plug and play or does it require coding. Its a Mk2 for reference.
