so in teh 90 535ia i tried to clean out the a/c

Klima-Cleaner is a high quality aqueous branded product which removes bacteria, fungi and other germs from airconditioning units without the need for disassembly. Together with the added odor neutralizers, its fungicidal and bactericidal agents combine to produce an extremely mild recipe with a broad spectrum of activity and high substantivity which will not irritate the mucous membranes. Any recommendations issued by the vehicle manufacturer regarding the cleaning of the air-conditioning system must be complied with.
after i sprayed it in, i waited 20 min for the foam to finish its job, and
as per instructions tried to start the car and turn the heat on full blast for
30 minutes.

the car didn't start though...the obc was flashing things at me.
let it sit overnight, still doesn't start, obc shows - 37C when its 44F here
and the display below the tach shows check control owners manual
i disconected the battery to try and reset everything, so its sitting there now

what do you think might have happened?
