Can the keys forget that they are coded to car if you mess around with the convenience module enough?
I have been playing around with my CCM as I am trying to figure out the wiring for the mk5 boot handle I have just fitted. After un plugging and plugging in a few times and locking this and unlocking that they have now stopped central locking the car via the keyfob.
Just locked the car via the barrel in the handle. Strange though...I have VAGCOM and will recode them, but not until I'v got the boot all sorted.
