My 1.8T AGU cut out on me and now wont fire back up, it turns over.. I can hear the fuel pump prime. Up to yet I have I have tried a different crank position sensor, cam sensor, ignition amp and replaced spark plugs. I have checked all fuses by the drivers door and on top of the battery. I have had it scanned but not with vag com, with only boost pressure valve the only code to appear. Anyone shed any light on this for me? TIA
