Buying aftermarket TPMS for winter wheels?
Do they need a first-time installation program, or the car just recognizes them?
Also do they need to be re-programmed everytime I swap wheels?
(For example on my 2014 IS350 I can only have 4 TPMS programmed at once which means if I were to have TPMS on my winter set, they would need to be re-programmed every season (120$) to delete the TPMS going out and program the TPMS going in)
Thanks.

Canadian models use a "passive" TPMS, wherein underinflation is inferred by using the ABS system to measure the rate of rotation of each wheel. This is theoretically less precise, but a whole lot cheaper and vastly simpler.
You can recognise the tyre pressure loss warning by the Run Flat Indicator active Restart with OK message which appears in the Service menu of the multifunction display. Information on the message display can be found in the "Restarting the tyre pressure loss warning system" section.
If your car has TPMS :
Information on tyre pressures is shown in the multifunction display. After a few minutes of driving, the current tyre pressure of each tyre is shown in the Service menu of the multifunction display.

Having had both I prefer the passive system as it is simpler and no extra cost when buying winter wheels.
Anybody know if there is actual programming involved, and if so, do the tires need to be removed from the rim again or it can be done from outside the tire?
My Schrader tpms's are Mercedes branded but are linked to a different MB part number than the one you state above. This is disappointing...

A lot of places selling TPMS sensors are confirming fitment on the C450, looks like a lot of misinformation out there.
Does the C300 have a different part number for the TPMS sensor?

Thanks - wish I had stumbled on this before ordering the sensors but it is what it is...
