2012 C250 - Computer Service Reset
I've searched this forum and cannot find out how to do it.
Anyone know for sure how to do it on a 2012 C250?
Thanks
Try this:
Close door, first turn key into position 1 . Then Press and hold "Accept (phone button)" on the steering wheel for 1 sec and then press and hold "OK" on the steering wheel until the menu comes up on the display. Choose option to reset service. Also, I believe the radio must be off.
