hey guys new to forum and hope some one can help with my audi a4 not starting

[Doctle Odd]

Need to check induction system, vacuum pipes, air filter, fuel filter and first I'd check the EGR

[imi]

sorry for typing above i meant to say fuel filter not oil filter (found oil in oil filter so needed to change it lol)
also i will recheck the egr again in lunch break tomorrow i think their is a actuator test on the scanner
is their a manual way to test it ?

[Doctle Odd]

Only the full version of VCDS can test actuator. Theonly manual test I know is "is it stuck"

lol if you mean stuck closed and just clicking when ignition is switched on then possibly

how does these egr work on diesels same as petrol ? open on cruse

i will report my finding tomaro

also is the fuel return supposed to be pressurized ?

also the car runs on ether on the button

STOP using ether! EGR in a diesel reduced the amount of oxygen getting into the engine and in doing so creates soot, carbon and other nasty stuff that jams valves and makes your car run badly, EGR Valve also worsens fuel consumption in a diesel, I don't think there's much pressure on the fuel return.

just a quick update i have gone back to basics testing the fuel system took single injector out at a time and check for fuel, then put back in and same to the next injector and so on, all are showing flow of fuel
but even with the injector out with few cranks of engine the fuel filter return is pressured (defiantly is not normal)
so i checked the running car and after a few cranks no pressure in return of fuel filter

what i would like to no is is their a one way valve in the return pipe at some point

my plans for tomara is to switch the tandem pump i am unsure of the used unit i have put on the engine it was one on the shelf i had,

also i have diesel in sump
injector seals are new

is their anything else i should do at this point ?
