997s TPMS How Long to Learn?


Recommended Posts

I wonder if anyone can tell me how long ot might take the TPMS system to learn when the system has changed because of a wheel change? The handbook just says ' a certain amount of time, driving' but doen't quantify that. 5miles? 10, more?

Any help appreciated.

It can take approx. 10 Km (6/7 miles) on a 997/1, if not, a PIWIS tool is recommended.

Thank you for that. I took the car for a 30mile run earlier. The tyre pressures are showing up fine on the display, but I still get messages that say:

Wheel change? Update data. (Or words to that effect)

and

TMC Inactive.

The data is all correct which is why, I guess, the pressure monitoring shows. The other message, according to the handbook, means TPMS is 'faulty', though for the life of me I can't see how I could have made it so. I think that the monitoring part is working but not the puncture alert part.

Any further advice would be much appreciated.

Could be that the batteries in the sensors are old.

Yes, you have to take the wheels off to get to the sensors

and replace the batteries.

The car will be 2 years old next month, wouldn't the batteries last a bit longer than that?

My vehicle is not TPMS equipped, but I seem to recall form other 997's that there is an area in the drivers information system where you indicate which OE wheel/tire package is fitted to your vehicle. From your description, it seems your sensors are communicating just fine, but system wants to know what tires are fitted. Your owners manual should have this process detailed. Let us know how it turns out. Good luck!

Yes, Ive done that - re-input the wheel data. It appears that the monitoring of pressures is working OK but the warning system for notifying pressure loss or deflation is inactive.

Thanks for the input, in any case.

A little off topic, wvicary, but the newer TPMS system on Cayenne MY 08, believe it or not, react in yards.

Well, in hindsight, after my last tyre detail re-update (!), the pressure monitoring bit of the system did start working within yards, showing the pressure in all four tyres. However, the warning symbol is staying on with a message saying TMC Inactive, which apparently indicates a fault and that the deflation warning bit will not be operative.

This I didn't know. I'm glad they have made improvements over the 2004-2006 models that I have worked on. Thanks for the information.

I had an issue getting the TPMS system setup when I switched from Winter wheels to my Summer setup. After several trips, the TPMS still would not register correctly. Another Porsche owner told me to drive around in circles clockwise and counterclockwise for the system to learn the wheel locations??.....I did it, and the TPMS system learned the new wheelset right away!
