speedtronic inoperative and wrong speed reading (digital)

Hi,

I just picked up the G55 from the mechanic after a gearbox oil change. Car runs well but now i have this "speedtronic inoperative" message as well as having the wrong speed in the digital dial. It shows KMh - the car is a lhd, and over-reads by 2x.


I used to be able to switch it to miles but now I can't. (edit, the odometer changes, but the speedometer stays in km/h)


I know the mechanic was fiddling with his star system to look at deleting the "foglight" error as my car has them removed. I wonder what's gone wrong there.

Thoughts?

Car is a 2008 G55K

You should go back and have him "fiddle" some more with the Star system. He has inadvertantly changed something.
