Got this code...

20A201 - Charge air, cooling system: Dry-running detected.

Car runs fine except that AC doesn't work and coolant levels in both reservoirs keep dropping below min. It's Weird. I've top off the coolant twice but drops.

Thoughts?

Sounds like there’s a coolant leak.

But it’s under warranty, don’t ask here, ask the dealer service folks.

Ask them to install rock guards as a preventative measure to help prevent small rocks from puncturing the radiator.

I'd just buy the CSF heat exchanger at that point that comes with a rock guard. Or you could buy OEM + rock guards and have yourself or a shop install for way cheaper.

Problem is I'm on road trip and need car ASAP to get back home. Otherwise, I would.

Call BMW corporate, mine was covered under warranty by my dealer! Didn't pay a dime out of pocket and now I have rock guards installed. Should have came that way from the factory....

Agreed. I filed an insurance claim. Will see where that goes. Next will try BMW if that doesn't work.

Btw...Rock guards installed this time around. However, they didn't install them at first, I noticed and asked service dude, tech said he "saw the box but didn't know what they were" ... 2hrs later rock guards installed. Had to basically do job all over again. Then there's one missing screw and a loose one in wheel well PLUS they broke the right trunk latch thinga-ma-jig. Wtf! Total amateur hour.
