Hello, My S3 ('03) is giving me some serious headaches.. It fails a lot when i smash the accelerator, and giving me misfire problems in all cylinders. Already changed the sparks, DV, cleaned the TB, new fuel filter.. I think the MAF is not ok either.. could the 4 coilpacks be mad? Bad coilpacks... bad MAF... ? The turbo only does about 0,3 bar boost.. N75? Here are the vag-com results: 5 Faults Found: 17705 - Pressure Drop between Turbo and Throttle Valve (check D.V.!) P1297 - 35-00 - - 16684 - Random/Multiple Cylinder Misfire Detected P0300 - 35-00 - - 16688 - Cylinder 4 Misfire Detected P0304 - 35-00 - - 16686 - Cylinder 2 Misfire Detected P0302 - 35-00 - - Thanks, Best regards, John M.
