A friends A2 TDi (2004 model) has got starting problems, with all the symptoms of a leaking fuel filter drain plug. First start of the day and most times it cranks over (and over) but does not fire up. He's started to keep the tank at least half full and parks 'nose down' which helps a lot.
I've not personally checked everything but have been assured the battery and starter are good and there are no fuel leaks or smell of diesel but the symptoms suggest an issue with fuel supply while cranking.
There are a couple of tests which don't sound too difficult but was wondering if anyone had already tried them -
Tandem pump fuel pressure while cranking
Pressure test fuel line from tandem pump to fuel tank
Vacuum test fuel supply line.
I'll add more posts with the test details
Cheers Spike
