Hi my name is Mark I’m in Los Angles and have lived here since 1975 I’m from Northfield in Birmingham . I have a 2009 A4 Quattro with a 3.2 and my car has a miss on cyl 1 -2-3 that are random . I have replaced all six coils and plugs and both oxygen sensors on bank 1 I cleared the codes a took it for a drive and put about a hundred miles on and came up with the same codes .The car does not lack any power but I do feel the misfire at idle i am wondering if any of you has had the same problem and if they new what could be the cause it only on bank 1 so could it be a cam sensor for that bank. I just don’t know I would appreciate any feed back about this annoying problem thank you Mark
