Hi my car has been running like crap for the last few weeks where it feels like it has no boost, i have checked for boost leaks tried a different maf and it still hasnt solved the problem.
I tried cleaning the trottle body earlier and hey presto it was fixed but it only lasted for a few miles and then it was back to its old problem, does anyone have any idea what the problem could be, someone has said about the egr valve but i dont know what or where this is.
I have a 1999 A3 Quattro 20vt by the way.
Any help would be amazing as its driving me round the bend.:blackrs4:
