ok,car takes 3-4 second to start,hot or cold it dont make any difference.

it will start (eventualy 4 seconds after turning the key) but at first it will not ,it just wont fire, to give you a better idea,as if there is no fuel
new filter plus the T-piece that fits on top of fuel filter and new seals,and no faultcodes via vag-com.

What should i do now!!!

also some smelly fumes can be smelt when standing with car running.
