coolant temp sensor pic

Makes sense.  It was probably disconnected related to the also-disconnected cold start valve, and
damaged wiring going to the same.

I should probably disconnect it again, until I rewire the valve.

Do you know anything about the oil pressure question?  I found some posts from me in the archives about
the buzzer going off on my last Coupe GT, so since my "other" sender is the same one that was buzzing
before, it's probably bad as well.

However, pulling the buzzer relay in the last Coupe GT made the signal go away, while this time I have no
buzzer sound but I do have the idiot light.  Is the idiot light triggered by the relay, and maybe I do have a
relay installed but with a non-working buzzer or something?  Or, is the idiot light on a separate circuit?

I remember now, even the relatively simpler (non-turbo) Audi's have their issues...

Thanks,

Ken
