I just got done replacing the two lower auxiliary radiators on a X3 MC. What the proper way to burp the coolant system on this beastly S-58... ?

On my daily driver an 2011 e90 335i with the N55 all I have to do is set the key to position #2, turn the heater on full blast & hold the gas pedal all the way down (with the engine off) for 10 second to initiate this process.

PLEASE HELP. THANK YOU IN ADVANCE...

I’m about to do a coolant change on mine. did you just drain the coolant from the hose connecting to the two lower auxiliary radiators? Also, about how much did you get out? I assume we should put roughly the same amount back in?

I can't remember exactly how much I took out. But it was more than I originally thought / imagines might be in there. I removed my front bumper & was replacing my 2 side auxiliary radiators. So that's how I drained the system during that job. I can look up the official procedure guide for the S58 & get you the name of that article. Then ask your local service advisor to print it out or look it up online. That should help a touch.

Thank you! I would appreciate all the info I can get so I can tackle this procedure.

You got it man. Just realized you live here in the bay area too. I also want a F87 M2 to park next to my F97 X3 M. Small world huh.

I fully agree. I had a MG 2017 DCT M2. But the dated iDrive & cheap gauges dressed down the interior even more. It was a sick coupe though. When the time is right I really want a MG 2018 DCT M2 with the sunroof. One day I'll know what it's like to have my ideal spec. Once I'm back home after the weekend I'll get you the name of that document.
