Hi there guys
The cars have not been in for a service recently have they?
We had a similar issue. The car went in to have the CCM computer's software updated. The reason it did it was because (You prob wont belive me) but the software for the CCM computer is American. But the computer itself is German. So they conflict with each other. It can happen any time.
CCM- CEntral convenience module. It controls power steering, central locking, windows etc.
Solution:
1. Take her in to be reset and if a reset does not help they may change the controllers software.
2. The car may have been in for a service recently and had the software upgrade. By having the software upgrade both boot opening and operation of windows via the key fob are disabled. Simply access the options via the highline computer and set them as you want them.
3. The coding may be out. Check the manual. There is a way to recode the key by putting it into the drivers door and turning it whilst pushing a button or something. I cant fully remember how.
4. If you dont have the highline... Pop into VW and they can change it via VAG COM. OR ask a forum member to help
