hi my first post here.


basically i got myself a cheap a4 1.9 td when driving it black smokes intermitently but when it does it smokes bad. also gives the feeling of running out of fuel.

my friend used vagcom and reset a fault code and noiced the water temp was low and the cold start was always on.

we changed the thermostat and it is noticabley better but still has intermitent black smoke. when e got the engine up to normal temp the cold start was showing as fluctuating between 20% and 45% closed. could this be normal.

thanks in advance
