Hello Two of my A2s were not build with remote keys. I have now upgraded one of these cars to have remote keys by changing the S version CCCU (KSG ) to a newer AC version and made new keys.   But now I started thinking. Does the older S version perhaps have the hw capability for remote keys? Would it be possible e.g. by VCDS to change the settings and "connect" a set of older (without the D suffix) remote keys to it? If so I could use it for my second car.
