Hi can anyone help me with a problem I have with my e270 w211.when you turn the engine on there is no faults on the screen.when you drive a few miles the message appears consumers switched off.I have checked the voltage of the small battery under the bonnet and it is 12.73 volts , when I check it with the engine running it still reads 12.73 volts. I have also checked the battery in the boot and it reads 12.7volts engine off , 14volts with the engine running.I have replaced the alternator and the battery in the boot within the last month so they look ok.can anyone tell me how the small battery gets charged ?? or what could be causing the error message. The battery voltage is the same with or without the error message.
Any help thank
Hugh
