HI folks, i am at my wits end, i am selling a psi tuning box for the audi 2.5 tdi v6, its the vp box,
My nightmare started last night when a chap arrived to buy it and wondered if i'd fit it for him..... i thought nothing of helping him out with it, but when we fitted the box, he wasn't happy that the performance was of any significant increase so we removed the box connect everything the way it was and now his car wont run!!!!!! GREAT!! so now i have some1's a4 sat on my drive that wont run, the problems i can describe are as follows, the car will fire and run for about a second and cut out, then if you try it again straight away it wont even fire, then if you leave it a second or two it will fire and run for a second and cut out, now the guy said that the orange light with the car and a picture of a key on it never came on before when you switched the ignition on, but now it does, it goes out when you turn the ignition on, and wait for glow plug light to go out it does too, but the damn car wont run, i am panicing that ive wrecked this guys car!!! please can some1 shed some light!!! have i possibly wiped the code out the ecu, or damaged the immobiliser!!!the car hasn't run since this occurred!! help me please................ many thanks steven.
