Reduced brake power start engine!
my car is 2005 w211 e 320
every week especially when the car is idle for a whole day I get a message "reduced brake power start engine !"when turning the ignition on .. it goes away after a minute .
Last month I replaced the sbc unit ,and brake part under the steering .
I checked the problem with diagnostics and doesn't show any problem .
Before two weeks I replaced the esp module(still get the message).
Please help !
Thanks
I checked the the main battery and the auxillary on the mb star diagnostics and showed no problem .
Still I need to check manually?
Thanks
and read the voltage, with a volt meter, before you start your car in the morning.... Still
