2000 VW Jetta TDI Auto. 220000kms.
Changed the timing belt 3000kms ago. Tweaked the timing with VCDS and it's been running like a top.
Driving it yesterday, timing sounded like it was advanced (rattly). Not great power....not much until I stepped on it then it would take off.
Rattly seemed to go away above 2200rpm.
Ran VagCom and got P1248 Start of Injection Timing - Control Deviation- Intermittent.
TDI Timing shows a vertical yellow line as way to far advanced.
Adjusted the fuel pump sprocket as far retarded as I could get it.
Still getting P1248 that I can't clear and the vertical line on TDI timing.
Not sure what's going on. Filled it up about 300km ago. Could a bad tank of fuel do this? Ran 2 cans of Diesel Purge through it with no change.
If I pull fuse 34 the timing really advances, showing me that N108 is working I believe.
Any ideas? I'm at a bit of a loss.
