Most of B7s come without heated side mirrors.
The cables are fitted and only a pair of heated mirrors are needed.
To take off the old mirrors move them to the upper most position.

Attach the cables and push the mirrors back in position.

The mirrors work when the rear heated glass is turned on and ambient temp is low (I tried them at 6 deg Celsius and they worked) but the temp threshold is not known.

Good write up, didn't realise it was that easy!
 
Brilliant! I didn't know that, where did you pick up the heated glass? Now that Winter has really kicked in I'd like to do this soon.

I need this so bad, every morning my mirrors are pretty much frosted over, I've found some on ebay for like £5, but apparently they fit 2001-2011 A4's.

Are they a universal fit?
 
I am not sure if they are universal. Check the labels in the boxes that the left is aspherical while right is convex.

I bought them both for 29 euro. I don't have the original link since the seller doesn't sell them anymore. From another search in aliexpress I found another seller.

Heating can be verified via vcds in central convenience channels 12 and 13

Do you need to play with VCDS to get them to work? Or will they work always when the rear window heater is on?
 
They work by rear window heat switch
