you buy the ones for your car, they will be the right ones. Try ebay or any other MB parts store. After you have the car ready, you reset the TPMS on the screen , all the pressures will go _ and drive it 5 miles, they will all come on

My 2005 SL55 doesn't have a visible TPM option? Is that an option that can be turned on with Star? Also a MB mechanic mentioned that the monitoring option on the sl55 only tells you that a tire is low, but not which tire. Can someone elaborate on this?

it will tell you which one is low and it will also give you a read out of what every PSI is in each tire at any time. When you initiate them you need to make sure they are pressured to the exact correct pressure, b/c this is where the system will then baseline pressure changes from. You then have to drive around 10-15 minutes without stopping. I have an extra brand new set of pressure sensors. PM me if interested. I was going to get a 2nd set of wheels, but I'm now not going to.

If they are dead, they need to be replaced. You can either go to the dealer and pay $300-$400/sensor, or Discount tire did mine for less than $100 per.
I would rather have everything working as it should, than just say F it.

I'm contemplating doing this. How have the sensors been working? Any issues? What was the total cost from Discount Tire including mounting and balancing?

I have an extra set of brand new sensors that I bought when I thought I was going to buy a 2nd set of wheels that I'd sell cheap if anyone is wanting a set.

2006 SL55 AMG
The 2006 Mercedes-Benz SL55 AMG (R230) generally uses a 315 MHz TPMS frequency for the North American market. While some later R230 models or non-US models might use 433 MHz, the 2003–2008 SL55 AMG, especially with part number A0025407917 or A0028209926, typically requires 315 MHz sensors

Tire Rack dot com sells tthe sensors they used to cost around $30 apiece nowadays they're around $60-65 each I think. My first two R230s (04 SL600, 07 SL550) were equipped with TPMS as an ordered option when built, my SL55 doesn't have TPMS! I wish it did. Why would a buyer order this car with a Pano Roof and not opt to have TPMS as well!!
These cars do use 315 MHZ units, and when installed, you simply drive a mile and they automatically begin connecting with the car, and are fine after that.
