Profile synchronisation/ date and time
I had a check engine light so I scanned it and received a code relating to parasitic drain so I found a thread saying disconnect the negative terminal battery for 1 minute and reconnect and the code should go which it did.
But now I my clock won’t automatically adjust nor the date?
Also I cannot sync any of my profiles from the Mercedes’ me app it says I need an internet connection
please any ideas what has gone on and any fixes ?? Thank you
