re: Do you let your vehicle warm up?

They wire in a switch that you press that allows it to start with the clutch out. The ones I've seen require you to do a specific sequence of actions before getting out otherwise the remote won't work. Cool stuff, but still too much risk of my car jumping into the kitchen for my likes.

It used to be tough on engines to crank with the ac on.

False

My M5 actually has rev lights on the tachometer that tick off as the engine warms up. Not supposed to shift above the beginning of the rev lights.

I did when I had a diesel truck.I dont now that I have a new gas burner.

People who don't warm up diesels are fricking themselves.

I thought my 5 series had that too, and I actually thought the feature was broken. They informed me at the dealer that it didn't come with it. On mine it's a wheel that would track down to a specific rpm, then move up as it warmed. Again though, it's not even activated.

There's a douchebag at work that does this just to show off his remote start keychain as if it makes him that much more superior than the rest of us.

I must admit I know very little about car maintenance but a mechanic did tell me that, although, in the early 80s. He compared it to redlining your engine.

When you turn your AC on max it nerely recirculates the interior air...nothing more. If ever it gets cold enough to freeze up, the small sensor in front of the cab fan will shut it down. No biggie.

GM alternator and compressors do sometimes have issues with high rpm use...but mainly the older units.

Some cars have a shut down for the AC comprrssor above a certain RPM. Mine deactivates the AC clutch at 5000 rpm or above.
