Hi
Hope someone here can help me.
Have an 2002 A4 1.9tdi engine code AWX.
The problem is the rev counter jumps up and down and the whole car shudders.
This happens more when idle but you can also feel it happening when driving.
I have changed the wiring loom for the injectors which helped a bit.
Engine runs a bit smoother.
Also this doesn't happen everyday. I'm only getting 40mpg out of it now.
Got it scanned notting came up. all clear.
Hope someone can help.
Thanks
Darren

I'd say you have a faulty fuel pump

would the fuel pump not put up a fault.
