No offence, and not trying to be a smart ***, but did you check for the obvious - that the tire shop moved your TPMS over to the new wheels? Looks like your sensors where not swapped over, or were damaged during the tire install. Check your OEM wheels. Is there a small rectangular module on the inside of the wheel at the tire valve?
The warning can be cancelled by clicking OK on the steering wheel controls, but it will come back next time you drive the car. Even after the warning message is cancelled, the yellow warning light will remain on.
Was fine after install, drove literally 1 or 2 miles and then get this error on the dash. I can't seem to reset it.
Any ideas how to reset it? Is anything broken?
if it was working fine after install, they probably just need to be "awaken" again. Bring it back to the shop, they should have a scanner-like gadget. Once its reset, drive it for around 10-15min. sometimes even less and it should read the tire pressures again.
It takes a few minutes of driving before the TPMS "polls" the sensors for their readings, so it's possible to not see the error right after leaving the shop. The TPMS are part of the valve stem assembly and they need to be transferred over from your OEM wheels. If your take-offs still have valve stems there's your answer.
I think that there is a menu item to rescan/reset the sensors, when I had weather change issues the sa used the menu to reset them. But I do not remember which sub menu it's in.
If the same sensors that were on the car before the wheel swap were still on the car when it left the shop there'd be nothing to recalibrate. The car wouldn't "know" the difference. My bet is the sensors are still on the take offs and the shop installed regular valve stems on the new wheels.

haha you are right! They are still on my old ones. It seems quite solidly stuck - do I take them off with a hair dryer?

I believe they are held on by a nut that threads onto the outside part of the tire valve (just guessing based on looking at mine and pics online).
Your tire shop should do it. Unfortunately it means unmounting your tires from the new wheels, installing the TPMS and reinstalling and rebalancing the tires.
So does the C Class have indirect TPMS or direct TPMS? I was reading that direct TPMS run on batteries that normally can't be changed so the whole TPMS unit x 4 will have to be changed every time the batteries go flat.
