KOOLCAR Posted yesterday at 12:02 PM Share Posted yesterday at 12:02 PM 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 yesterday at 12:02 PM Share Posted yesterday at 12:02 PM 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 yesterday at 12:03 PM Author Share Posted yesterday at 12:03 PM 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 yesterday at 12:03 PM Share Posted yesterday at 12:03 PM 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 yesterday at 12:04 PM Share Posted yesterday at 12:04 PM 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 yesterday at 12:04 PM Share Posted yesterday at 12:04 PM 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.
