short version:
new 2007 cayman s, delivery in march '07. tpms system transposing front and rear wheels, thus creating "flat tire" warning in rear tire(s). now on fourth repair visit...dealer has replaced sensors in wheels, antenna/transmitters, control module, and wiring harnesses prior to this visit. dealer now working with pcna to systematically resolve this issue. anyone else have these problems? any suggestions? started looking into my lemon law rights here in pennsylvania, but in all honesty, i don't want to wait another 4 months for a replacement (if that's the resolution), not to mention the legal hassle of depositions, hearings, etc.
also, dealer logged over 350 miles on my car during the last service visit...says the road testing necessary to reset the control module. does this sound unreasonable to anyone but me? phone call and letter (certified) going out to pcna on tuesday.
any input would be much appreciated.
Sounds like your tech is not up to speed. The TMPS module reads the report from the individual wheel antennas so they sound like they are incorrectly positioned. The time needed to set the control module will vary but shouldn't take more than 25 miles at the very most. I sort of doubt that all those things were replaced as well (wiring harnesses?). Something is very fishy. Can you take it to another dealer for a second opinion?
I'm also going to guess it really is a bad module. Porsche requires the dealers to replace all the inexpensive parts before allowing the module to be replaced. Make them show you that they really did replace it.
Sounds like the dealer is ripping you, at least for miles driven -- for what?
350 miles sounds like they really liked driving it!
I don't buy their accounting. It smells fishy.
That fact alone makes me distrustful of that dealer.
That is outrageous and I am glad you have the letter going out Certified to PCNA. I hope they jump on this one.
Good Luck and let us know how this goes.
My TPMS system starting acting up yesterday. I will call the dealer.
They swapped out my wheels. Carrera 19 to boxster 18 before I bought car. I will check that they swapped out the sensors. Gauges suggest the reading are correct.
Thank God this thing is under warranty.
Did you have the computer relearn the sensors after the swap?
Also, 350 miles is way our of line for the dealer's service dept test drives. Even relearning the sensors shouldn't take the car more that 4-5 miles on the road, so I agree 25 miles would have allowed them to reprogram 5 times.

I just got back from a Memorial Day weekend trip to Asheville from Charlotte. My TPMS gremlins started acting up again, this time with the left rear. Had me worried the whole way (2 hr drive) as the pressure kept decreasing in that tire. Got to Asheville, and the tire was down only about 2 pounds if that. Car sat in the Grove Park Inn garage for two days and then miraculously no problems on the way home. I am sure it will act up again after a few days.
These TPMS systems are going to be problems until they get this technology right, not just with Porsche but with everyone. I seriously doubt you can enact the lemon law over something that really doesn't affect the performance of the car; after all it is just a faulty warning light. As I have previously stated...this system sucks and I hate it.
