Mercedes-Benz Eco stop start troubleshooting and general information video by Mercland

Thank you for the refresher. For info on a 2013 W204 with stop start, if the car has not been used for 2 weeks or so the green light in the stop/start pushbutton will not illuminate until the aux battery in the boot has charged after about 25 to 30 min driving, when this happen the hill hold assist function does not work until the aux battery charges adequately.
