Hi Grant

I don't know if this helps or not, but I find that I have hot start
problems if the van sits longer than 15 min. The 2.0 Audi requires a
fair bit of fuel pressure and the stock vanagon pump I am using may be
suspect. I don't think it has a check valve in it, but Jetta's etc do. I
am thinking about changing fuel pumps. One difference though is that my
FI is CIS-E and yours I believe is pulsed. My poor starts do clear up
rather quickly once enough fuel is getting thru. I had never considered
an electrical problem, but that also a possiblity for my setup. As you
say, there is alot of heat in that engine bay.
Good luck.
