can i say that that quote you got is very good P.R and great advertising gismo..... thers been a thread before about it i think? but anyway, in regards to correct functioning (lol) VAG have gone something really wrong somewhere..... as alot of turbo cars do.....
every turbo car comes with a recirc dump valve..... these are placed in because they are there simply to ruin your turbo.... its so the drivers have to buy consumables i.e a new turbo every year..... when they recirc, they force air more back into the turbo the wrong way, causing it to stall, lag, chatter and spin the WRONG way for a second or two.... this puts loadsa force on the turbine itself and even the housing, causing whichever to crack first......
i completely agree that it makes it run not as it should, as everything in modern cars is controlled by electronics etc.... but its only telling the engine is hasnt got enough air making it componsate for it with petrol! lol! so therefore runs rich and spits flames like a jet! this can be overcome buy fitting a CAI..... i think? BSC Hons Automotive design, thats what they taught me!
i dont want 2 offend anyone, but the myth id say is Boll*x..... if anything will break it'll be a sensor...... me thinks?
