I managed to flatten my battery by leaving the key in the ignition in the garage. After a charge everything seems back to normal except for the wing mirror folding function when you press and hold the close button on the key fob. I checked the door controllers 42 and 52 with VCDS and the coding is o.k.

Does anyone know what might have gone wrong????

The windows may need a reset,I think you open front window fully,close and hold switch up for about 5 secs

Thanks, that worked.

My car door mirrors did not fold back on locking after my garage replaced my car battery. 
the simple fix described here worked just fine.   Thank you.   Bob
