Airbag light came on and off a few times last month, then one day I got a xmas tree on the dash, literally every single thing.. parking brake, ABS, ESC, TC, airbag, adaptive lighting, etc....
It would go away eventually though and sometimes not show up but after a couple of days it was almost constant.
After scanning, there was a code for intermittent rear right speed sensor connection to the ABS module... so hopefully that was culprit or else its the actual ABS module, or possibly the wiring.....
The xmas tree has not come back in 2 days but im still apprehensive to assume its solved though.....
Seems to be kind of common, saw a post on reddit this morning with a guy with the same issue.... same symptoms and everyone commenting how common it is... especially in tropical environments....
