2021 M440i lost A/C and some other problem
I stored my G23 cabriolet M440i 2021 in october 2022.
BMW has installed a trickle charger 4 amp under the hood.
Since then, my engine is making randomly relay noise somewhere on the engine. My rear defrost is flashing all the time and I lost the A/C and warmer control.
BMW tech does not understand the problem. I disconnected the 48 v battery at the big connector and let the hood open for charging.
Very sad. Search everywhere on the net without any success.
Any idea please? Thanks.
