The Engine needs to turn at 280 rpm or above to hot start.
A few issues can cause this
Old Battery.
Poor earth. (bi-pass from negative battery terminal to engine with jump lead to check earth)
Coolant temperature sensor worn out, will show working, but they wear out.
Relay 109 on the engine relay panel.

Only know this because we had a passat with the usual faults.
If only a Volkswagen were as reliable as a Volkswagen !

I've heard of this fault when looking up the same problem with our VW touran. Particularly check out the "lazy starter motor" daft I know but a real problem.
