Hello everyone,
Just purchased s63 replica wheels and tires with tpms sensors, installed all of it on the car and sensors do not work. Tried to pair them with a car and car says that wheels have no sensors and of course the tpms light is on. So pissed. The sensors were silver in color not sure if oem, where should i start? Am I doing something wrong? Is there a trick? Thanks in advance

What did you do with your original sensors? They'll swap over. It's possible the new ones aren't the correct frequency, so they'll have to come out anyway.

Mike's most likely right that it's the wrong frequency. I didn't want to spend the extra hundred or so per wheel when I swapped the stock 18"s for 19"s so I used the original TPMS. Check the charts at the tire store. If you have a pre-facelift W221 I think it's 315 and after the facelift it's 433.

I want to keep the originals for the winter set. Looks like I need 433 hz and i probably got 315 hz. Where is the best place to buy sensors? Tire rack?

Or EBay has pretty good deals on them.
