KOOLCAR Posted 3 hours ago Share Posted 3 hours ago I had a message on my 2017 A220D that said "consult workshop" without shifting gears. When I put in a new battery and turned on the EML, the car started right up. Restarted the vehicle after clearing the faults, but the same issue reappears when the engine is turned off. I charged the battery again and drove, but the same problem occurred after turning off and then turning on the ignition. What's strange is that the following day, I checked the battery with a voltmeter and it only read 11.v. Please let me know your thoughts on this.

BENZE220AMG Posted 3 hours ago Share Posted 3 hours ago It seems like you're experiencing a significant drain on current. You installed a new battery; why? Perhaps hiring an auto electrician is the way to go. Quote Link to comment Share on other sites More sharing options...
KOOLCAR Posted 3 hours ago Author Share Posted 3 hours ago The problem could be due to a low battery voltage, according to what I read online. Quote Link to comment Share on other sites More sharing options...
BENZE220AMG Posted 3 hours ago Share Posted 3 hours ago An indication of overnight current drain is 11 volts on a brand-new battery. The voltage should be higher now. Although EML can be triggered by low voltage, it typically turns off after three driving cycles. Quote Link to comment Share on other sites More sharing options...
EtherealWanderer Posted 3 hours ago Share Posted 3 hours ago Have you recorded the error codes before erasing them? Did they exist in the present or were they preserved for the future? Quote Link to comment Share on other sites More sharing options...
mrnobady Posted 3 hours ago Share Posted 3 hours ago A handful of fundamentals: Make sure the battery connections are secure (now that you can feel them), and then find out how much power the alternator is generating. Is there a start/stop function? Is the right battery being blamed? If the battery isolator is malfunctioning, for example, the error codes mentioned before might indicate it.
