I have a 2021 M3LR and just today run into an issue where the boot (trunk) will unlatch momentarily from the button, in car display, or app, but the boot fails to lift and just relatches. Also looks like the in car graphic shows the boot lifted slightly? No errors indicated though? Boot shuts OK as normal if you have manually lifted the boot when it momentarily unlatches. Is there some calibration routine to work through or is this going to be my 5th warranty visit the SC..?
