2012 C300 TPMS Warning won't go away (Canadian Car)

Hi all,

I have a 2012 C300 Canadian car and the TPMS warning comes up every time I start the car. I clear/reset it in the menu it but it just comes back after a few minutes. I know the tire pressure is good in all the tires and there are no leaks. Because this is a Canadian car I know there are no actual TPMS sensors, it uses the wheel speed sensors. Has one of them gone bad, but not bad enough to throw on the ABS warning? What should I be looking at here?

Thanks

You need a Mercedes specific scanner. Launch makes one that's pretty good and not terribly expensive.
