Hi guys I have e350 with distronic plus lately it’s deactivated all the time by it self for days and it’s again working normal for like 30 mins or hour and then it’s deactivated again and this deactivated adaptive cruise control and blind spot and pre safe break I replaced both batteries main and auxiliary with OEM ones and the issue still there scanned the car and found those errors and cleared them but the issue still there any ideas for this issue
Is that the exhaustive list of ALL active faults? Try not to single out these 3 front modules to consider ALL modules that are acting up.
Radars + ESP + ...
These being "stored" means it's not a hard fault but a part-time transient condition.
You can try to figure what these modules share that makes them actup: chassis bus, power...
One module can disrupt the bus and spoil coms for perfectly good units... you can disconnect radars to see if your ABS/ESP works normally.
Trust this particular module is not built to fall apart prematurely unlike the radars that are not waterproofed.
Has this car been repaired for a front collision ... radars?

Did you replace both batteries at the same time? I had similar behavior with non-communicating control modules and I had to disconnect both batteries at the same time to get the messages to clear. Disconnecting and reconnecting individually did not clear the error. This is when I had a weak main and was trying to nurse it along by regularly charging it.

Not at the same time the problem is it’s sometimes working and most of the time not working
If you have a multimeter I would check your new MAIN battery for its current state of charge and also it’s value while car is running and battery is charging. They sell weak or dead batteries from time to time and you may have one. Takes 5 minutes

i had an issue with eco before and after changing the battery the eco is working fine which means that the battery is good and its OEM battery

I already replaced both batteries and btw no problem from abs /esp
