hi everyone I have e350 2012 and lately I get the message radar sensors deactivated automatically and this deactivates the distronic plus feature and pre safe breaks as well it can stays for some time days like this I have read that this may be due to something causing frequency interference and it’s should be back to working again after awhile but is it normal that it’s stayes like this for days !!!!! And this is happening a lot lately in different areas and roads

Start with a check of your main battery state of charge. A weak battery will shut down power robbing features one or two at a time to preserve the battery for more critical operations.

Distro+ sensor

Your Distronic radar is center front behind the big star or the square plastic as shown above.
This module has a front row seat for head collisions and it's connector make it subject to environmentals: heat, rain, dust.

Before you're forced to take a part the front grill or bumper, have a look at data through OBDC in search for obvious clues.

This long range radar is normally stable unlike the proximity radars under each headlights... these two have affinity with ghosts.
