Hi,
I switched from my 20" wheels to the OEM 19", and I got fault message after about 30 min learning and it was only showing the front right and rear right sensors... I tried learning several times, but with no luck... Ok so I figured that both left sensors was bad/flat battery. I took 2 of the sensors from my 20" that was working and moved to my 19" wheels. I still cant get the display to show the left sensors... I have tried at least 3x30 minutes, but with no luck. Any suggestions? I have tried both summer and winter settings... About 36 psi front and 44 psi rear.
My 20" sensors that was working, was blue and was called I-Sensor or something like that. All are 434 mhz. So my left sensors are the non-oem blue sensors and the right hand side, are the oem grey sensors. Could it be that all 4 sensors must be the same brand?

Thanks

 

You could try the aftermarket relearn by turning on the key and dropping the pressure then re pressure the tire.

 

Hi,
I have to drive about 30 km/t for the learn process to start. The way you suggest is key On, no start, dropping pressure for all wheels to what pressure? When key still on, raise pressure to suggested pressures by Porsche?
Sorry if I am slow, but never heard of that method before..
Thanks

 

Basically yes but it is supposed to be running.
From a tpms site

2006-2009 Porsche 911; 2006-2008 Porsche Boxster; 2006-2008 Porsche Cayman TPMS Relearn Procedures
1) Put vehicle into relearn mode.
2) With the engine running, deflate each sensor/tire 5-8psi.
3) Reinflate to the door placard specifications.
4) Drive for 30mins.

 

Ok thanks

 

You can check battery life of each sensor using a Durametric/PIWIS to see which one has failed. If one is flat then the whole system will fault.

 

Thanks
I ordered 4 new sensors today. Hopefully all good when I replace them

 

I hope you ordered oem because the aftermarket ones are a pain most of the time. I had a set that went in and out every time I drove the car.

 

No I did buy HUF RDE001 sensors. Have read that others had good luck with them. Hope they work for me as well

 

Update: Finally the package with the sensors arrived. Well, it was only one sensor instead of 4, and it was dirty and propably used... Fast forward, I ended up using my sensors from my other set and it calibrated in 5-6 minutes of cruising at about 50 mph. All well now

 

How did you fix this issue? im having the same issue

 

Read the post above yours

 

Thanks for helping me out as well. I am also facing the same problem.

 

Not my video but it worked for me.
