I have a couple of things that are sounding bad, 1 since it had a service!
Under extreme acceleration I get a squeak like old cars got when the fan belt slipped, any ideas?
The bad one!! I picked the car up from Readiong Audi, and had to put some fuel in (BP ultimate) minutes later it started to feather? and the emission light started to flash, then it cleared. this continued and its in Audi today for a check, now last night I heard a big Whoosh and a pop, just after it fluttered, could this be the Dump valve giving up?
Any views helpful
