Audi A4 Tdi Fuel Cut Off Switch

14-04-2009,10:22 PM

Hi everyone i'm new to this site so i hope im posting this thread in the correct identify. :-D I bought myself an Audi A4 quattro 2.6 V6 (1995) and the clutch is stuck then a friend tried to kickoff information technology on gear with clutch pedal downwardly, he did this several times and quite aggresively. Since and so the car will not offset atall and i now know there is no fuel coming through and was told it was the fuel cut off switch possibly as with all the sudden jerking around may have allowed the car to believe it has been in a collision and cut off the fuel supply. Would this brand sense?? Also where would i discover the switch to reset it?

Thanks in accelerate, Dan.

Information technology is part of the air bag deployment system, a signal shuts downwards the engine ECU so no big blindside from the bike and information technology isn�t the cut out.

Thanks for your reply, would disconnecting the battery for a while aid reset this? or perhaps getting it plugged into a dagnostic computer and clearing/reseting the fault codes stored in the ECU?

A fault code read is a good idea but unless you accept a deployed air pocketbook hanging out of the steering wheel the engine cut has not activated.

It turned out not to be what i suspected because the next day it started straight away...?????? Today it was fine until i parked up for an hour then got in it and, withal over again information technology only wouldnt starting time atall? How tin i diagnose this fault? Is information technology possible to practice a domicile diagnostic like you can do with the erstwhile vauxhalls and crossing pins 2+iii on the diagnostic plug? then counting the number of times the engine management light flashes?

Thanks, Dan.

So do i need professional equpment to diagnose it? As well does anyone know if the Audi has Some saftey features to protect the engine?
i.e if the oil level was too low would it stop it from starting so as to not damage the engine?
A friends mercedes has this feature and broke down and could not start it again,... when the AA guy came out he checked the oil straight abroad and later on topping information technology up it started.
My oil level is fine but the oil level warning low-cal is flashing.
Whatsoever ideas anyone?

Yes it has, the Audi had been sat for a yr and there was a leak in the sunroof which soaked the 2 front end footwells. I'm now assuming the reason you lot askeed is because in that location'southward some important electricals in the passenger footwell?? I take had it valeted and all the water has been vaccumed out and right at present i have dehummidifier in the automobile to remove any moisture left in information technology. Will this cure it or will i need to replace/repair something?
Thankyou for your suggestions and help mate!
