My 2001 jetta turns off while running then i have a lot of trouble to maintain on I hear a grinding sound after turning switch


i would recomment replacing the fuel filter. it is the number one reason for TDI running problems. the grinding noise, if it is heard only when cranking could be the starter and also could be a failed dual-mass flywheel.

2003 tdi, 54 k miles, bought car new, had manifold cleaned, new glow plugs and harness. car has been driven only short commutes for 3 years. Heavy blue smoke at startup, then it clears right up. No...


valve seals are going. when car sits excess oil gets past the valve seals then when you staRT up it burns the oil off then runs fine and no more blue smoke. It is fine to run like that had the same in a dodge caravan 1996 6cyl. ran another 100 000 km. and still ran fine got rid of it for other reasons.

Glow plug light flashes on97 tdi sharan


on some diesel engines the glow plugs will cycle after the engine is started. it does sound like your glow plugs are not all working that would cause the hard start and excessive smoke when it does start.
