[V8] Block Heating

[Kneale Brownson]

You Audi owner manual says to avoid idling to warm up.  "No warmup is necessary".  Just drive off conservatively until the engine reaches normal operating temperatures.  By then the tranny and chassis lubes should be sufficiently exercised to not be harmed by aggressive driving. 
   
  I think the reason Audi advises against standing warmups is because the ECU makes startup fuel mixtures very rich, and just standing dumps unused fuel into the cats and contributes to plug fouling.

  Thank you Bob. That helps me make an informed decision. I just need 
someone to drive the car around town while I work (and put gas in it) 
then pick me up and let me tear into it. ;D

Y'know, I have a theory. Every person that says to "never let your car 
idle to warm up!" has a garage...
