Question on Launch Control use on the M3 xDrive Competition, I know in the owners manual it states that the Launch Control won't work until after an uninterrupted of at least 6 miles so the engine is at operating condition.

My question is this, if the engine has gone 6 miles or more and now the engine is at operating temperature, and if you shut the car down for say 10-30 minutes, but the car is still at operating temperature - will launch control work right away? Or after shutting down, no matter what the engine temperature is, does one have to drive a minimum of 6 miles?

sucks that launch control needs basically a cool down after each use.

In my Pcars, if the engine cools down enough when you turn it off, then you have to wait til its a the proper engine temp before you launch again.

the info in the technical manual somewhat contradicts this.

1) it states that the prereq is engine at operating temperature and says 6 miles is just an "approximation" of when the temp should be reached.

2) it states that whether an additional launch can be performed or not is based on the oil temperature, there is no actual requirement to drive around for any distance.

i haven't tested for myself but i'm inclined to believe the info from the technical manual over the owners manual which is likely dumbed down.

Pcars can do like 100 in a row it seems
