Head Unit - Steering Wheel Controls Don't Work, Please Help !

[harridean]

Hi Guys
Need some help in finding what's caused a problem with the steering wheel controls for the head unit.

My T6 recently had a minor minor paint repair to the drivers door which involved taking the electric door mirror off, and while in the shop the door was left open so the battery went flat, since having the van back the steering wheel controls for the head unit don't work and it does recognise the ignition is on, also have to manual switch it on and off. I have checked all fuses and checked all connections at the rear.
Any assistance will be very much appreciated before I take in to VW.

Thanks
Dean

This is very unusual and weird.
Side mirror, battery flat because of internal light?
And then MFSW issues, real mystery.
Any progress? I am curious what actually happened

I'd suggest getting it scanned and see what errors have been logged.
