Hi
Anyone got any ideas, i seem to be going round in circles
Origonal fault, car went to have a new alternator belt fitted at kwik fit because it had broken, after this they could not then get the car to run properly, they fitted new map sensor then a egr valve then new kats and sensors !!!
Got car in, checked it over got map sensor fault, realised vaule was out, yes you guessed it, when belt broke part of it went under cover and caused timming to jump a tooth.
Reset valve timing, cleared code, road tested, all good. Problem now is after a 20 mile run code 17559 \ p1151 mixture adaption range 1 (bank 1)mixture too lean. Tried a new front lambda sensor and map sensor, checked for air leaks, checked compression, engine breathers, checked fuel pressure etc, had battery off, reset adoptions, i seem to be missing something.
hi george having had new catalytic converter & sensors-are they genuine vw parts?these dislike pattern parts.also the egr was changed-recheck the the pipes around egr for air leaks or maybe cracked & finally smoke test & vacuum test all the small vacuum pipes,this fault may have already been there in form of a small misfire. hth colin
thanks for replies,left customer to drive car about with a data logger on it,he brought the logger back, car was involved in a crash,waiting to find out if its being repaired or not.
