hi al really looking for some professional help [sorry its a long thread]
i recently got my self and audi a6 2.5 tdi year 2000 with a diesel pump problem the car would start run for a round 30 seconds then just make a noise from the pump then cut out so first of all i run a diagnostic check and came up with fault codes ;
01318
00546
01376
these codes to me said disel pump EDC was knackered so rather than do the right thing i decided to buy a diesel pump from ebay at the cost of £235 trying to save money mmm
anyway got the new pump through fitted it to the car and didnt work so back to diagnostic came up with the same fault codes so after scratching my head i then decided to send it to audi they came back with diesel pump does not require coding on this model advise wiring checks as tank pump not supplying fuel to the injection pump so i wasnt convinced it was anything els apart from pump so i got the car sent back before the cost grew decided to start looking at part numbers my origanal pump no was 0470506016 then i looked at the pump no on the one i bought it was 0470506002 different numbers so my first question is could anyone tell me even that the pumps are identical why the pump numbers would make a difference
with the origanal pump fitted i could here the fuel pump priming under the rear back seat the glow plug light would go out and the car would fire up with the new pump fitted i now cant here the fuel pump the glow plug lights up goes out then beeps and then the light flashes it cranks over but does not want to fire up or even think about it now it its like its immobilized so i plugged in the old pump loosly in the engine bay just to see if i could get the pump to activate the fuel pump under the seat and stop the diesel light from flashing even now with that one connected it does the same no fuel pump activating and glow light beeps then starts flashing and this is where im at with it stuck if anyone reads this and has any advise i would be most grateful
thanks jay
