hello guys, im pretty new to the whole vag scene and after a few months of owner ship started having a few warning lights flash up on the dash? the engine check light has come on and when i scan for faults it comes up with p0102 (maf reading too low) and also p0172 (too rich) although the car drives fine? really smooth, just worried this could be causing further damage? ive replaced the maf and fiddled the connection and erased the codes but they still come back also the esp light has come on after i uncliped a little box on the inside of the passengers side wing to fit my cai pipe? could this be a problem or something further on? although this doesnt really affect the driving as i prefer it with no esp, i dont like way it cuts in and shudders the car to try and back it go straight? so for all the waffling but any help would be appreciated?
