Had my A3 T Sport 9 years now and its always be loyal, never let me down, was thinking of upgrading to a newer model Audi and it seems to know and its playing games... When I put my foot down to build up speed a bit quick it seems like somethin is slipping, although I know there is nothing to slip.... been told its so many things, knackered turbo.... or the engine is on is way out, not sure if its either so thought I'd ask fo a bit of advice, being a woman I dont trust garages without having an idea of what up so any help would be great
