This bracket is only usable on older types of Audi TT (pre 2015). You would have known this if you had bothered to look up the specs.
Waste of money on this birthday present
The product was just what the reviews indicated. The holder is extremely well crafted and aligns perfectly with the A3 8V model fan outlets. You might need a screwdriver to neatly pull out the fan units but other than that it was a really easy installation. I have used the swivel magnetic holder from the package and it grabs with the magnetic plate really well (even with a phone case). You may even attach your charging cable with one hand on this holder which left me amazed 😎
I would recommend this product to anyone looking for a good phone holder to Audi A3 of this generation.
