It's reasonably well established that the S65 needs to be at operating temperature in order for the oil to provide adequate lubrication of the low clearance bearings at high loads. I've had BPM make a software change to lower my red-line to 4500 RPMs when cold and the red line increases linearly as the oil temperature comes up to goal, but I also eliminated the cold start routine. I'm 6 months into M3 ownership and still learning.

Mine is a daily driver, including short trips to the store, and has modest mods (stage 1 tune, test pipes, cold air intake, power pulley). For folks who daily drive their M3, how long do you sit there idling in the driveway on a morning cold start before taking off? To the end of the cold start routine? Until the oil temperature is visibly rising on the gauge? Until you shift it into gear?

Currently I let it idle for about 30 seconds and start my drive, keeping RPMs low until the oil temperature is around 180F.
