Mechanical Compatability of TPMS Senders: 997.1(& 996?) vs. 997.2
Hi Folks,
I have figured out that the TPMS technology changed between 997.1 and 997.2 and I think that the 997.1 used the same type of TPMS as the 996, but that is not compatible with what the 997.2 uses. Does anyone know if the 997.2 type TMPS senders can be installed in 996 turbo wheels? That is, are the 996 type TPMS senders mechanically compatible with the 997.2 TPMS senders? I know they are not electrically compatible, but I am very much hoping that I can successfully install TPMS senders into these 996 turbo wheels that will work with the 997.2 TPMS system. Does anyone know if this can be done?
I have posted the same question as an addition to my thread where I was asking if the 996 turbo wheels would fit on my car (997.2), hoping to get more eyes looking at the question.

I'm not sure if this will answer your question.
6 years ago I traded my '05 C4S (996 last of) for my current '09 C2S cab.
I swapped the winter wheel/tire combo from the 996 onto the 997. I had to
install new TPM's and they worked with no issues.

Thanks ogun228. I think that does answer my question. I sounds like you were able to replace 996-compatible TPMS sensors with ones that are 997.2-compatible. This what I am looking to do, and it sounds like it will work.

Done!
I had the TPMS sensors I ordered off of Amazon installed today, and they fit the wheels OK and were picked up by the car right away and seem to be working fine. I bought HUF# RDE048V21 which are 433MHz units that are already coded correctly for 997.2 cars that use 433MHz TPMS. No more TPMS error light on the dash, and I'll know right away if I have a pressure problem. Yay!
The parts look like this:

If you buy the correct sensors (as above) then the car (997.2) can just learn them. If you buy a "universal" version of the sensor, then a special tool (that some tire shops have) is required to "customize/configure" the sensor to be the right type for the car. I think this style of sensor exists so that tire service shops don't have to inventory so many sensors. Then there is also the concept of "cloning" existing sensors, for cases when it requires dealer-only equipment to make the car system learn new sensors. In that case, 3rd party tire sellers can use a tool to read out the ID of each existing wheel sensor and then "clone" that ID into the new sensors. That way the car system doesn't even know the wheels have been changed.

With my 2008 S, I replaced the sensors and dove off. After a couple on minutes of driving the car the new sensors were picked up by the car's software. Note: make sure the old sensors are not in the car ( eg on the floor or seat) or near the car or the new sensor signals will not be picked up. After I continued to drive I found the sensor signals were lost. Later, a dash message came up asking me if I had replaced the tires ( yes). Next step, I went into the menu using the stalk. In the menu, I had to choose 18 or 19 inch wheels ( mine has 19). I had to choose summer or winter tires. I also had to select full or partial load. I don't remember if I had to save the settings or simply exit the menu. After that no issues with my new sensors.

I didn't think TPMS was offered on the 996 - it first appeared in the 997??
