For those still with ultrasonics that may be on the fritz:
Apparently the air suspension compressor may give off EM interference when adjusting ride height, causing the sensors to think they have failed. Service wrapped the wiring with foil to shield it and fixed the issue for me. If anyone else is getting frequent “Park Assist Unavailable” with the sensors near the wheels giving off an internal fault while in service mode (s1,s6,s7,s12), ask service to see if this is the issue.
