All Porsche sensors are 433 MHz. Site lists the sensors for your car, many cars use the same sensor. If you have aftermarket wheels they may need a different sensor. Call them if you're still not sure which sensor to get. Wheels need to be rebalanced any time the tires are removed.

 

I just registered after suffering from severe dealer pricing shock. I am in Canada and have a 2007 C4S Cab, which I bought new and have put on only 14,500km - less than 10,000 miles. The TPS system has been acting wonky lately with misreadings and warnings, and on doing some research I found this forum.

Based on the experiences from the members reported on this thread, I just ordered a set of the OEwheel sensors and will report back how they worked out for me. Thank you all for doing the legwork and sharing it here.

A local dealer quoted me over CAD1000 just for the 4 sensors and I just do not have the heart to spend this king of money. Another dealer has quoted me CAD 1800 for a major service, which is essentially a change of the air filters, cabin filter, oil filter and oil change and inspection/cleaning of the drains. Are these guys for real? If the cost of servicing the car would be more realistic, I would not hesitate of having the work done at the dealer, but CAD3000 for basic maintenance is a joke.

 

Just joined. Thanks for all the helpful research. Just ordered a set of ITM TPMS from oewheels for my 07c2 (http://www.oewheelsllc.com/TPMS-Sens...2#.U5jdr_ldXNs) $201 shipped. Eyeballying a set of Hankook Ventus V12 evo2 from tirerack. Rear ContiSport are running thin and although fronts still had life, both had a patches. I know, I'm a nail magnet...

 

I just got an extra set of wheels for autocross/track use and my original wheels have the original TPMS (2008 997S) with one battery starting to fail. My mechanic suggested disabling the system in the car so I don't keep getting all the lights on the dashboard.

With two sets of wheels plus the fact that I'm always checking/changing tire pressures anyway, I'm definitely having the system disabled and I will not be replacing any of the sensors.

 

I think you can disable it with the Durametric Professional.
