Remote central locking not working?
I have been trying to use VCDS to diagnose the central locking fault on my TT with only limited success and wondered if there is anything I can try.
Both key fob remotes have stopped working, so the following has been done without any success.
Key fob batteries replaced
additional keyfob purchased
Central locking module replaced.
Manual re sync of the keys. Hazrd lights dont flash
VCDS shows no errors, but..... measuing block 6 should show when any button is pressed on any key and at the moment it is not showing this. It also shows correctly that 2 key remotes are already coded to the car. Also tried using adaptation CH 21 to add the additional new key but again the key is not "seen".
So now I am left scratching my head because the locking module has been changed, so what else is there to change? Only thing left is the Central locking antenna but where is it?????
