will do...but my 08 manual really doesnt say much

i can do the settings in the tpc menu

then the car automatically will go into a "learning" mode

will try your suggestions of course

 

One possibility, some metal valve stem caps disrupt the sensor function. In fact, porsche only sells plastic caps for the tpms rims. Maybe three peice rims with all the extra hardware sets 'em off???
just thinking out of the box.

 

u r right, u should only use plastic caps for any wheels w/ tpms...that part is covered...i have tried everything, will continue on...

 

so an update:

i have tried putting the pressure higher, tried the summer-winter reset, driven etc...still wont learn

again all sensors are working and sending the proper signal...PIA

fortunately winter is coming and my stock sensors will be back on in a month or so so i will be able to see if they are recognized, then maybe figure it out in the spring if it doesnt work by then

 

Do you have to reset TPMS after new wheels/TPMS? OR will the car just automatically relearn? I have 2008TT

 

Handdoc, any updates? Did you resolve this issue... Bc I'm having the same thing and would appreciate any input. Thanks!

The Porsche sensors read 2-3 PSI too low, I bought some from TireRack for much cheaper and they read no more than 1 PSI below actual (checked by multiple gauges).

In order to reset the sensors, I have found that you need to go at least 5 PSI above the recommended pressure, i.e., 38 F-44 R and drive around a bit. It should not take that long for the sensors to pick up the pressure. Then get out and reduce the pressures to where they should be.

I have tried this many times at the track where I run 28 PSI cold and the TPMS has a fit for the whole day and then I fix it after the day is over via the over pressure trick.

Give it a try and let us know if that worked. If it doesn't then I am willing to bet that something else is going on with your tires.

Cheers.

 

i had to replace the ones from tire rack...couldnt get it to work otherwise...i used my factory ones and there hasnt been one issue even 3yrs later!
