if it is a tdi, the problem is usually that then it could be an a8 that mounts I have the 3.0 tdi, or the 2002 versions with the 3.3

if ? the 2.5 tdi is not to go crazy with the glow plugs....
most likely the problem ? the pouring off pump in the tank...
practically in the vessel c'? a kind of "controserbatoio" in part separated with suitable bulkheads from the tank, especially true that contains a certain amount? diesel,let's say around 3 litres,that serves to get around the intake of the pump there is always a positive quantity? of diesel fuel, even in curves more "tough" with a little diesel since the sebatoio and very wide...which audi have thought of putting a blower that when the fuel falls below a certain ****llo will restock this "controserbatoio"..many times? the sensor is responsible to start this blower is not v? and, therefore, leave to dry, the suction of the pump....
remove the tank lid and check if this controserbatoio c'? diesel..and saw that you are with the open vessel off the sensorino from his home ? right there in front of you and your coco(? a small gallenggiantino black in color with two wires) and see if by moving it,with the ignition on ,can you hear the pump starting....
