Hello friends.We have strange problem which is driving us nuts... This audi 2004 year 2.0 tdi 140 hp turns off the engine while driving.its happens when is at 2000-3000 rpm for even on idle when the engine stops it wont start again untill we put startimg spray into intake while crackling ..... So far we ve cheched few things: battery voltage is 12.8 v at off engine when the enginre works it charge ot 13,9 v which is ok perhaps....we ve uplug the returning fuel pipe from the fuel filter and measured the outgoing fuel which is 0,5 litter for 60 seconds sharp ot idle on warm engine is ok or not cos somewhere ive see that it must be 1,5 litter. Vcds logs no error at all. Anyone had the same problems and where to searh and what to check Thanks in advance for any helpe
