It is quite a common accurance on diesels buddy. Something to bear in mind mate is that if you ever contemplate having your A4 remapped ask the tuner to do an EGR delete aswell as the stage 1 map as this closes the valve thus allowing your engine to run alot better as its not having hot recirculated gases going back in to the engine. If you wanna do a complete delete then great but no need as you can map the EGR out.

Thanks for the info I was thinking ov having a egr delete I have allready had the dpf removed and had it remaped is it ok to still have the egr delete ? And do I remove the egr valve itself with a racepipe or does it stay and just map it out ?
