I think I already know the answer to this, but I thought I'd ask the question just in case.
I've just replaced my door mirrors with some nice crome S4 folding mirrors and I've also replaced the mirror switch, hoping that would enable the mirrors to fold, but it didn't.
I've had a look in vag-com, but I can't see anything referring to the mirrors. Does this mean that I would have to replaced the control modules in each door?
My current modules are:
8E2 959 802 B
8E2 959 801 B
Think it might need extra wiring if it's the same as the older cars
Hope this helps
