…. its gone wrong - never seen one that excited - its going to need decent diagnostics and some new parts - what who knows - has it got very wet and flooded the Front SAM - that's normal on a Mercedes but not commonly reported on a W221
SAM (signal acquisition module) controls stuff and sends info round the car to do stuff

If unable to diagnose with proper MB SDS system, replace BOTH front wheel speed sensors (OEM only).
Takes about 30 minutes each side, minimal tools. Hardest part is putting the connector retaining clip back on.
I have had two w221s that displayed same things your dash is displaying, and both times it was the wheel speed sensors.

when the ABS sensors break (they do on every 221 made) the park brake usually becomes random with extra beeps and its off when you had put it on, or refuses to auto deactivate, a few months later the ABS ESP light comes intermittently and eventually doesn't go away - with good sensors it all goes back to normal
