Hello i wonder if anybody come give me some advice please.
I have a 2.0 TDI A3 2004 156000 and it has started to judder like mad and some times cuts out.
When the accelerator pedal is pushed down hard i coughs and splutters but if you lift of for a split second it goes off.
I have removed and cleaned the EGR and anti judder valves and have this morning replaced the diesel filter and it is still doing it but since i have changed the filter i have noticed the tick over is erratic..
I am stuck and hopefully somebody will have an idea to what it could be so any ideas please.
