997 TPMS issues..

[wjmlucas1979]

Hi,

I am struggling to get my TPMS to connect correctly, they worked fine when i bought the car but since swopping the sensors for new models they won't connect. I have gone through the dashboard menu and it goes into learning mode but fails to connect after 20-30miles of driving.

I have even bought a TPMS reader to read/activate the sensors but to no avail, not sure if i am doing something wrong?

The sensors were described as correct for 997 and the reader shows them and states battery is healthy so I'm lost.

Thanks,

Warren

Are you sure the new ones are correct type and frequency? Might be useful to find another member near you to try swapping one wheel with known working TPMS and see if your car learns that one sensor.

Can you post the year of car and type/number of sensor? Gen 1 and Gen 2 cars have different sensors.

Hi Warren, I am assuming, based on your other post, that you have a gen 1.5 997TT. It is my understanding that the only sensor that will work with that MY is the HUF RDE001. There may be others that will work but they need preprogramming to emulate the RDE001’s.
Do you know what was fitted to your car? The sensors were different for the MY2010 997TT.

Hi Steve, correct, I have a 2009 Gen 1.5, i will have a look into the specs, I am hoping the TPMS reader i have bought can programme them correctly but struggling to make sense of it at present, appreciate the advice.

Thanks,

Warren

Hi Geoff,

Thanks, I know it works as it read the factory sensors in my original wheels no problem, I think the issue is the new sensors but i was hoping they could be triggered with my TPMS reader device i bought, I will do some more digging on specs.

Thanks,

Warren.

If you haven't seen it here is the latest HUF fitment guide. RDE 001 has been superseded I believe. Did the Gen 1.5 go to 433mHz? I think the Gen 1 cars were 315mHz?

My understanding is they are 433Mhz and can be a real PITA getting the car to relearn them.
Have a look at this pistonheads discussion....

The posts by lingus75 are particularly worth reading. It took him 90 mins of driving before they were recognised!!

My man at our local Porsche Indie says it can take hundreds of miles if the system is left to learn the new sensors but the codes can be programmed in which saves all of the driving!
