Hi there guys, I am new to this forum.

I have an A4 1.9tdi auto 2004. I have a two issues with my car and I am not sure if they are related. So I was hoping for some help please.

Issue 1: When approach traffic lights, roundabout, or anything which requires full halt, my car judders (when cold. After it has come to full stop it gives a last judder too.

Issue 2: When trying to take off and pressing accelerator does not rev at all, pedal goes down completely but no revving, Occasionally, if I press the pedal real slow starts to pull but most of the time won't rev at all and won't go. I initially thought this would be a gearbox issue, as I've heard this models have gearbox issues but now I am starting to suspect it might some kind of sensor related problem?

Lastly, when I bought the car (3months ago) i could hear the turbo making a sweet sound, now I am not sure if I can if I can hear it again. Maybe not related but I thought to include this info too.

Any advice would be greatly appreciate it please.

Thanks
Erion
