[V8] cold no-start

[Andrew Schlueter]

Mine is starting to have the same issue, I know my fuel reg is shot. I am
waiting to get an adjuable one to run with my supercharger project.

15 minutes???  What is the ambient temp?  Is it getting to be well below
freezing?

I'm not thinking coolant temp sensor myself, but I suppose it could be.  If
you have a way to read out the ECU data blocks you can read the temp value
the ECU sees.

I'm wondering if you're having a problem with fuel pressure.  Have you tried
warming up the battery and topping up the charge before attempting to start?

I haven't seen the V8 to be as susceptible to low battery voltage as other
Audi models, but it could be.  Can you tell if you're getting spark?
