Surprise Dashboard Warnings
I posted this on the S63 forum:
I have a 2020 S63 with 30k and no issues until yesterday. When I started up, 3 warnings popped up on the dash screen.
Active Brake Assist Functions Limited
Active Lane Keeping Assist Inoperative
Active Blind Spot Warning Inoperative
The car has had no issues in the 2 years since new. I have an appointment with the dealer, but would appreciate any advice. Bad sensor? Weak battery? Software?

When I see (multiple warnings), I usually get optimistic that it maybe related to one (single) isolated sensor issue.

I had those issues on my 2014 S550 and it turned out to be a weak auxiliary battery. Replaced the battery and the warnings went away.

What did they mean by a "bad sensor Module in the rear bumper".
I have an S560 (In Australia) and recently had 3 warnings after someone bumped my rear bumper corner in a car park. Quite a hard bum looking at the damage on their car compared to just paint scratches on mine).
Did you mean a sensor (as in rear parking sensor) or was it the rectangular radar control module that connects to the actual 4 sensors on the back bumper ?
Thanks

It’s the modular that’s in the bumper. It’s held in there in a bracket that seems to be brittle and breaks and creates the module to move and shift.
The dealer changed the modular but still had the messages. Then they took the bumper off the second time and duct taped the module to the bumper to make a more secure fit.
My guess is that the modular is no longer making good contact with the bumper.
Good Luck.

thank you for the quick response.

my car did have a knock in a car park at the passenger rear bumper corner.
it helps me narrow things down.
much appreciated and I will circle back with what my solutions turns out to be.
