w166 350 Bluetec. ECO mode jerking.
My eco mode is jerking at my ML350BT 2013. Not working for many days, even for long therm driving eco dont go active. Suddently it works again for som days. Both main battery and aux battery is brand new.I used a foxwell scanner, and the only parameter who block the eco mode from working is "683 Combustion engine, NOT OK" All other eco Start / stop parameters is OK. I also tested with the scanner when ECO is working, and then this 683 Combustion engine is, OK. So thats the reason
But what does this mean?? Wich part is bad??Regards
