Hi I've recently purchased an A5 that had previously been in and accident and repairs had been carried out before my purchase , both of the driver's side doors have been replaced and no longer lock on the central locking ,the car is a ,63 plate would the modules in these two doors need coding as they aren't the original modules or do I need to get 2 modules that match the car ? Any information would be a great help as before I purchased I didn't know these two doors didnt lock also the indicator on the drives door mirror doesn't work I presume this is to do with the modules ?

 

You'll need to get the modules coded so they'll talk to the rest of the central locking. Does everything else work on the doors or electric windows/mirrors etc. I ask as it could be a loom issue. If looms are different?
