I had this problem a long time ago, this list did not exist yet. The problem
was intermittent, i.e. it would occasionally not start when hot. Once when
it would not start, I decided to check the spark from the coil wire by
pulling it off the distributor cap, then bringing it near ground and having
my wife turn the key as if to start the van and me watching the spark. Then
I put the coil wire back on and tried again to start the van, to my surprise
it started, although reluctantly, like a flooded engine. Ever since then,
when the engine was hot and the van did not start, I used that trick and it
always worked. I'm not sure why this allows the van to start, but I drove
like that for almost a year trying out various parts. When it happened to
me I didn't know it was the temp 2 sensor, neither did the VW trained
"technicians". After they replaced many parts to no avail, I finally went
to a one man garage specializing in European cars and told him the problem.
He put two and two together, no start when hot so it's temperature related,
aha! the temp 2 sensor. Problem solved. I still have a spare computer,
hall sender, air flow meter and coil which are perfectly OK.
If you don't carry a spare Temp 2 sensor, disconnect it and attach a
resistor which is approx. the same as that of a hot engine resistance
across the leads. Now you will need to carry some resistors.
Wait till the engine cools off, then start it.
Buy a Temp2 sensor as soon as possible, and replace it.
Learn to be your own mechanic if you insist to drive a VW van.
