AUDI A4 1.9 TDI 130 juddering at low revs

[ed b]

Hi Guys

Need some help my B6 A4 1.9 TDI 130. It starts up fine but once my coolant temp reaches 90 it starts to judder when accelerating between 2k - 3k revs and the orange triangle light comes on and when I'm stationary the car shakes. Now after around 3-5 mins of it doing this, if i turn the engine off and back on it clears the warning light and works fine for the rest of the journey.

Car has been serviced just over a week ago and this started happening before the service.

Any ideas?

Could be caused by injector wiring harness, but you will need to do vcds scan to confirm

You need to get it scanned. i'm expecting you to find fault code 17669, which is either the injector harness or an injector problem.
