Recently purchased my A2 but it only has one key and the remote locking won't work. Central locking works fine from the key , no error codes showing when scanned with vcds. I've searched on here and found loads of useful information and tried reprogramming the remote both through the ignition and also using vcds. The remote has been tested by a car key centre company and works but they reckon it's an aftermarket remote . Using vcds it won't recognise the remote and they couldn't get it to program either. I'm awaiting a quote from the car key company to supply a complete new key/remote/transponder and also a replacement remote for the current key. My question is, in people's experience, is this likely to be an issue with the convenience module rather than the key? The code on the module in the car ends in AF. I asked the company if it was likely to be an issue with the module and they were quite emphatic that it must be the remote at fault.
