Hi all,

I've just replaced the engine in my B7 Avant, the car had been sat for a month or so with the battery disconnected.
I had to reconnect the keys to the car today once I got it up and running so that the remote central locking would function again.

All seems fine, but I have no electric windows, no electric mirrors, door lock button on the drivers door doesn't work, etc.

Plugged it in to diagnostics, as expected there was a mass of fault codes from everything being disconnected and the ignition being on occasionally.
Cleared them all and expected it to work... still doesn't.

The only fault code the CCM has thrown up again was one relating to an electric mirror? should have made a note of this in hindsight.

Have read elsewhere on the net that with older VAG cars, touching the battery terminals together will fully discharge the CCM and often clears up issues.

Before I try this, has anyone else had a similar problem, any suggestions, is this a re-coding required issue?

Thanks in advance.
