Hi all, well i own a A4 Quattro 1.8T AJL Engine and it has a running fault which cannot be fixed?....what ever the throttle position when you floor it it stutters and mis fires a little then carries it thorough and is using an amazing amount of fuel? ideas??.....Now before you start im a mechanic and no my way around a car so scanned it and fault codes (N80) (N75) (G70) Came up....which is charcoal filter short to ground......boost pressure control valve short with ground and Mass air flow sensor signal to low....so i replaced all units and still same fault and same codes....i used 3 different scanners from a snap on modis to VAG-COM Bosch ones and still the same result....i have checked the spark plugs they are fine as well as replaced the fuel pump relat as all wirirng seems to got through that on a wiring diagram....i have also with a multi-metre checked the injectors and coil packs and all seems fine? the turbo hoses and and all vacuum pipes seem ok ad well so any ideas??
Many thanks people Matt
