Hi,

Suffering with the 2002 Polo 1.2 e at the moment. It's been throwing fault codes like it's going out of fashion. Seemed to have dealt with most of the problems, but the major one still remains -

VagCom block 015 reports Misfire occuring on Cylinder 1 at warm idle. Which obviously makes it run like a bag of spanners in a washing machine. Coil packs/plugs have been rotated and the fault doesn't move. Injector resistance is equal across the three, but I haven't been able to swap them round (as I have no idea how to go about messing with the high pressure fuel rail). Previous fault codes have suggested that it's running rich, but then if unburnt fuel is getting through to exhaust I guess it would say that.

I'm aware that this engine is a piece of... erm has it's problems with timing etc. I have checked the camshaft marks and they appear to be in the same orientation, although it could have slipped on the crankshaft maybe.

Anybody got any experience of this problem or know of anything to try?

When you go into the engine section in vag com and read the measuring blocks on the AZQ engine do you have the label file displayed in the top right or does it say none or some sort of error. Thanks

I think that you should now be checking for damaged wiring - ie to that coil
