Quick question. I just picked up an additional set of wheels and tires for our C300 Coupe (C205 so should be the same system as W205) and picked up an additional set of Schrader OEM TPMS from eBay (I'm a little apprehensive they're fakes since the cost for all 4 was only $60 total, vs $70 each on other websites and $150 each from the dealership).

Anyway, assuming I get them installed and they're fully functional/legit sensors, how do I get the car to recognize them? Is there a procedure to get them to recognize and calibrate them that I can do myself or is a dealer tool necessary?
Lastly, will there be a problem if I store the old wheels next to the car in the garage? Like, will the sensors fight for recognition and dominance?

just drive it around for 10-15mins at a constant speed above 30mph. If it still doesnt recognize the tpms you have on, any tire shop or the dealer just needs to activate or "awaken" the tpms sensors. They usually point a gadget at the valve stem for a few seconds. Then, you drive it around again for 10-15mins.
The wheels you stored in your garage won't "fight" for recognition because by the time the computer reads the sensors you'd be out of range from your garage.
Hope this helps, good luck!

If they're active the car will recognize them but there's another step you have to take per the owners manual. You do have to drive it around for 10-20 minutes and then go into the assistance graphic screen in the gauge cluster. Go to the TPMS screen and I can't remember if I had to hit "OK" first but there should be a prompt that says "accept new values?" and you have to say yes to that. The thing is though, make sure you check the tire pressure before you go and make sure it matches what's on the screen so you know it's accurate. I just did this with my snow tires and rims.

I keep my winter tires/wheels with TPMS stored in the garage, right in front of the car, and have never had a problem with the AMG figuring out which wheels to listen to

I made an offer for less. The reason I got these was because 1) they claim they aren't fakes. 2) They come with the attachment nuts

My impressions so far when I got them is that they look legit. They have the Mercedes logo and so far they were detected and registered by the car with no issues. They were installed with no issues and the PSI reads 1-2 higher than my Joes Racing Tire Pressure gauge which is fine for what we're using them for. So far so good!

Is there any way to recharge the tpms sensors.. one of mine has a low battery I think

mo11

I don't think so. The battery seems to be sealed together with the sensor. I'm curious however if it shows a low battery fault message. If you do have a faulty tpms on your new car, it should be covered under warranty.

I hate active TPMS just because a few irresponsible Ford Explorer owner dies for not checking on their tire pressure. And everyone has to pay.

A passive system is just as good without sensors if people maintain their cars like they should.
