Hi all!


I'm new here. I own a 2017 c43 with no issues at all except that after the speed of 80 km the analog speedometer gets slower than the digital speedometer by Around 25 kmh difference.
there is no code in the car when it was checked.
the correct speed is from the digital speedometer in both gadge cluster and head up display.
I'm running stock rim and wheel size

Please help!

Hi guys!


please help.

No idea here, but clearly something is amiss. Likely software. This requires a trip to the dealer. Is the car still under warranty?

+1, I would take that into the dealer

Hook up obd2 and see if any error

If not unplug the battery overnight and see if it resets anything.

If you have warranty, best to bring it to the dealer.
