May be wear on the camshaft resulting in a marginal fuel supply at idle — if so the failure to fire will gradually become more frequent.
Pushing the pedal down feeds more fuel, hence it starts.
(Just guessing, of course.)
Team.
Vehicle MY07 Jetta DSG 103kw
Had a search, have not found what is happening or possibly about to happen.
Has occurred twice in two weeks,after the car has been running for approx an
hour,(doesn't seem to occur on shorter trips), when the car has been turned off
and left for short period say 5-15 minutes ,when then trying to restart the motor it will
turn over but not fire, you can try a number of times but will just crank over and not fire up ,
If you push the accelerator down while cranking the motor comes to life.
Have no display warning symbols at this stage.
Had a look at a few injector failure threads but they seem to be mainly for the 125kw motor.
Maybe a sensor somewhere ???
Thanks All.

More than likely this is a sensor issue, or an injector issue. I would get it scanned as soon as you can. I believe there were some people that reported similar symptoms just before injector failure (caused by the wiring loom fault).
Camshaft wear was really only a problem for a certain production run of engines, mostly in north America.
Quite unlikely to be a mechanical fault.

Check battery voltage when cranking, as well as cranking speed. Cranking speed needs to be higher than 280rpm before it'll fire.
Could also be a starter motor on it's way out.

Thanks Guys will let you know the outcome shortly.
How did you go, I'm in the same boat with my jetta.
Same here. Please let us know what the problem is

I have the same issue with my wifes Audi A3 (05, BKD 103KW)
It's driving me crazy, have to crank for seconds sometimes. If i abort cranking, and then crank again, it pretty much starts instantly
cam sensor
