No, verify it with other thermometer, but most likely you thermostat is stuck open.
My 2008 no longer has thermostat, but computer-operated electrovalve.
That adds to troubleshooting and cost as well.

It's a common problem. I replaced mine with a Wahler thermostat which is OEM for MB. It's pretty much identical except for one spot that would have the MB logo and that's scratched out. I also replaced the pulley, belt and tensioner while I was it it because one of the pulleys has to come off anyway to replace the thermostat and those are also known to go. Gas mileage also improved slightly after I did it.

Just changed it but it seemed ok, it should be open if damaged??
It had 2 springs and 2 caps, both seemed opened.
The surface was clean and smooth everywhere
I am skeptic if it was damaged
