Hi I need help. My 3.0 TDI stalls when idling and when coming to a stop at intersections. VAGCOM reported fuel pressure problems but I am not sure what the code was. An independent Audi specialist checked pressure regulator, filter and pump, no problems there. He does not know what the fault is. I also noticed hunting rpm at about 1100rpm. The stalling only seems to occur after engine is at normal temperature. rpm dips once and then stalls. Is really frustrating. Please help if you can.
