Audi 200: hot start problem...

[Gerard]

Thanks. :) When I call him I'll offer my Bentleys provided they wear
surgical gloves to handle it. :) I will see what he has checked. I've
kind of glanced over the CIS section, not paid much attention to it.

I looked through my bentleys earlier while tracing a high idle problem
for someone. One thing I didn't spot was a decent chart for
troubleshooting things such as "hot start problem" across systems.
