S63boy

Hi all, i recently picked up a lovely S63 convertible, only 20k km on the clock. Car went to Mercedes for B service and came back sparkling... I had a long road trip over the weekend , about 1200km of Highway.
at a certain point i came across a heavy rain storm, visibility was close to none and call myself lucky to have found repair at a near gas station....

The morning after while highway cruising at 130km/h an alert popped up and the lane and steering assistance went off... the message on the dashboard saying "

Pre-Safe Inoperative See Owners Manual "

I wiped the windscreen and front bumper (the one on the left of the mercedes logo) sensors to see if any dirt would have caused the issue... but unfort the car still reporting the same message on the dashboard...

Any hint on what could have happened? don't really want to bring the car back to Mercedes...

Thanks for any help

it happens often for no reason. Usually when you shut the car off and lock it. then turn it back on it goes away

I am in the United States, but recently went through all of the codes that have been stored in my car, and there were codes for these modules. They were soft codes alerting me to what happened when it went out of operation. Many times this is due to rain, infiltration in the connectors or the module but this time it logged the completely random occurrences as electrical interferences. It’s not something I have ever seen logged before and I wonder if it’s because of all of the 5G infrastructure they are putting everywhere. 5G also upsets my radar detector K a band, which previously never had random interferences. 5g is a total sham in that it creates more interference, requires more infrastructure, and you lose service on devices even when standing 100 feet from an antenna.
