yes there is another thread all about my tale of woe but in a nutshell
Had a knocking on the car that they traced to injector 5 which they replaced FOC audi good will
Had a further noise that was a injector seal.
Car is now stuttering between 1200-2000 rpm but only if you accelerate under load. Its fine in sport as that puts it above 2k. its worst in eco mode in fact its undrivable really in eco as when you accelerate it feels like you are going over a rumble strip.
Audi reseated all the injectors which has made it better, but did a further compression test. Cylinder 5 they say is 20.6 within spec but 4 other are now reading 18 to 19.3. They say the heads need to come off as they suspect the valves are not seating. 22 hrs labour which I may or may not have to pay for depending on what they find. They say It could be a new engine !!! which I`d have a 30% to pay.
Its doing my head in now, I suspect further injector failure but they say they test ok , but thats a laptop telling them the open time.
any ideas are gratefully received
