Hi,
I just registered after googling and stumbling upon this thread after digging through the forums.
I have the exact same symptoms you've described on my 2014 A5 Coupe 177PS S-tronic Quattro. Frankly I'm searching for grounds to reject the car since I can't terminate my finance as I've had it just over a year at this point. MPG loss and less power accelerating.
Not acceptable for a £26k used car that would be over 30 brand new with its spec. The insurance is a fortune, the tax is crap, MPG was pants anyway, and now I'm putting even more diesel in it yet getting less power. I accepted those compromises for "ok" MPG of around 40-45 and great power and AWD. Now its much muddier and is getting low to mid 30 MPG.
I don't like my chances of getting out of my agreement, but would really appreciate your emails from the VCA as that may help my argument along with other customer accounts.
Cheers
