Some of you may remember I was having some poor running/idling problems with my AUM engined A3 1.8T which (I thought) was solved by fitting a new temp sender.To be fair the car has been driving better and no more hunting whilst idling but today I have noticed yet another problem. When accelerating the car feels like its holding back then will suddenly surge ahead as if there was some kind of blockage its not violent though. Thought I had resolved the problem for now anyway still no warning lights but do I have a boost leak or something else ?
Thanks all
