Hi,
I have w210 E230 CDI, 5/10 times happens that when I drive with a constant speed without using brakes for like 2-4 minutes then abs/bas/esp lights come on. I reset them by rotating my steering wheel and switch off my car, and after 1 minute when I start the car, all goes fine. what could be the reason?

NOTE: Brake switch has been tested and its working perfectly fine.


Thanks
THG
 
Dear, the place where I am currently deployed does not have ANY good workshop in radius of 500KM.
Anyway, I have 2 more recent observation, as below:
1-abs/bas/esp Lights only comes on at night, (means when headlights are on).
2- when ever I switch on my headlights my car acceleration decreases.

I think the problem is with some voltage leakage or reduction to the system.

Thanks,
 
and 3rd important observation is that even with full headlights and AC, abs/bas/esp Lights do not comes on AT LOW SPEED. The problem only appears when I cross 40KM/H with headlights and AC ON and does not use brake paddle for 2-3 mins.
