I am sure this has been discussed here (no results on a topic title search) but here it goes... In cold weather climates (say 32f or below) who lets their car "warm up" in the morning before driving off. And if so, how long? As I recall this is a topic of some debate. My 02 1.8T owners manual says "To avoid unnecessary engine wear... do not let your vehicle stand and warm up. Be ready to drive off immediately after starting your vehicle." (3.1 p102). I have really never let it warm up in the past but recently have done so on a few (0)f mornings. Any thoughts?
