While I've been retired and Audiless for a couple of years, I still have
a couple of friends with elderly Audis and they rely on me for service
help. In this case, it's a problem I never encountered while I was
wrenching. Hot start, pretty often; cold start, never. Once the car
sits and becomes completely cooled off, it takes an extended period of
time to get it to start (like 1-3 minutes of fiddling). Giving it even
the slightest throttle makes it worse. Once it's up and running, no
problem, and it runs really well. The cold start valve works, although
I didn't time it, the control pressure is under 2 BAR in 75+ degree
weather today. System pressure is within specs, too.
Before I dive into this, anyone here inclined to give some informed
Thanks for your time.
