for the past 4 months ive been trying to get my car sorted with no luck. I have a 2.0tdi 140 A3 with a juddering misfire issue, this only happens at idle, i have read countless posts on countless forums and im not getting anywhere. This misfire goes away at just over 1000rpm and sometimes spikes between 800-1100rpm, when i hold it at 840-50 it usually calms down, ive read about rear cam timing being off...is this easily fiddled with and could it be the cause? the car drives perfectly fine over 1000rpm btw so far i have changed: DMF and clutch mounts EGR today i changed the Injector loom hoping it would cure it.....NO its not the injectors as they all seemed to be firing fine on vcds I checked the car today and the following faults were found: 16565 - fuel temp sensor A (g81) - implaussable signal 16497 - intake air temp. sensor(g42)-p0113- signal too high 18000 - altitude sensor/boost pressure sensor - p1592 -implassable correlation 16622 - manifold pressure/boost sensor(g31) -p0238 - signal too high 16486 - mass air flow sensor(g70)-p0102-signal too low 18072 - control circuit for PD injectors - P1664 - 000 - electrical malfunction 16785 - EGR SYSTEM insufficient flow, intermittent why would the egr be saying that after its just been changed?
