AC/heat turns on automatically..

Hi All,

i have a weird issue that is getting on my nerves, I flashed the car using cobb and now my AC turns on by itself while driving, i think cobb has nothing to do with it, but just wanted to point that out. Anyone had a similar problem?

Thanks

I know at first I thought the car was haunted too, what I did yesterday is when it turned on I changed the passenger setting from 61 to 60, then turned it off and it stopped. I hope it doesn't come back.

Ur a/c turning on and off/. Fan changing settings, etc. all these ghost issues are usually related to the final stage resistor. Common long known BMW issue. Had this in my e39 and have seen it in e9X
