Random Electric faults!! Plz help

[Mkar]

Hi, I am facing an uncommon problem with my C class 220 07. Last 7-8 months car showing ESP control unit internal fault. I sent unit for scan and reman to Actronics but they didnt find any issue in that part. Engine noise increases when error comes on dashboard. One guy suggested to change burnt tail lamp board and I did it but no success. My MB pro scanned and noticed random part errors are coming each time he has done Xentry scan. Now he is confused that these are fake errors and where to start.
Another issue is car doesnt store faults after it switched off. I found these faults only keeping the engine on.
Anyone faced similar problem or any advice please? Please see pics for last scan. Thanks!!

How old is your battery, as if it’s starting to fail I have seen in other makes this can cause spurious electrical fault codes?

Hi, I bought car on 2016. Since not changed. Dont know about previous owners.

Had similar problems with my 05 CLK. would always start, some times no instruments, indicators, EM light etc.
New battery fixed the problems. Battery now in my 190B. Newish MBs are very fussy on battery voltage.
