Hey Gareth
Not sure what the difference is between independent and a trusted body shop is but I have no aversion to your suggestion at all; I just wanted Audi to diagnose the problem and then go from there and then was happy to go with the most affordable option.
The problem itself is fairly minuet, but for some reason Audi have said it takes 8 hours to remove to leaves and twigs and dry out the carpet lol.
Is what it is, it doesn't seem like there is an easy way around this and unfortunately and I am unable to repair it myself for free, although I wish I knew how to!
Thanks for your assistance on this.
