Just got back from 50K service and MCU replaced. Went out to garage without my key and tried to use the app to unlock. No go. Everything else works. Can honk horn, flash lights, vent/close pano roof, turn climate control on. But I can't unlock. The status shows that it's unlocked but touching door handles or hatch button does nothing. Now if I get the key and open it that way, as soon as I press lock on the app it immediately retracts handles and locks. Any ideas?
