A few weeks ago I had my car washed and suddenly received a notification from MercedesMe that the battery was dangerously low and to drive it 30-60 mins to recharge it. I drove it with for 30 mins and the indicator in the dashboard was still showing red. The sat navigation / media dashboard screen is completely off and only works when car is in reverse mode, but it’s turned off while in any other gear.
The next day I had a long drive of 2.5 hrs each way, so I though it would definitely charge the battery, but after the long day of driving it was still showing on the dashboard as red.
I had the battery checked by Kwik Fit and they advised the battery is charged and working fine, and suggested that it must be a wiring issue.
I am taking the car into the dealership to be looked at but wonder if anyone has ever experienced this issue and if so what was wrong.
Any suggestions is appreciated.
