Mirrors do not fold after flat battery

[26DIPP]

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

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
