Just had the timing belt changed at Audi Glasgow in my wife's TT. The TT's 5 years old and has done 38k miles on it. After we got it back, the engine has a different sound to it. It sounds more when slowing down, as if there is a secondary engine breaking sound to it when slowing the engine.
They've suggested it's just the fact it's a new belt, but not too sure. Anyone experienced anything like this ?
