Can you program out the TPMS function from the car? I have some BBS wheels that do not accept TPMS that I would like to use without the warning lights in the dash.

I "think" the dealer may be able to with the Porsche PIWIS system. There is no way for an owner to DIY that I know of.

I wonder what would happen if the TPMS control module was simply unplugged from the CAN. Probably throw an error code but it shouldn't cause a CEL. Easy enough to try at least.

I was thinking I would try this to see if it would work.

It'll throw an error if you just unplug it, too.

I'm sure the PIWIS can disable it, though the dealer might not be willing to do it since it means they might also then have to accept liability if something happened. It's a federal government mandate that all cars sold in the US after ~2008 (? I think) have tire pressure monitoring systems. It was a reaction to the Ford Explorer rollover problems with tire blowouts IIRC. Since it's a "safety" item asking a dealer to code out TPMS is probably going to be met with the same response as to a request to code out airbags, the ABS system, the CHMSL, etc.

I can tell you that, on my 987 Cayman, using a DuraMetric Pro (a "cheap" version of the PIWIS that can do some of the PIWIS functions) I was able to code out the TPMS system. To my knowledge though, you can't do any coding with the Durametric on a 958 Cayenne.

If I were to get a set of TPMS, have them installed by a non Porsche dealer, I'd have to go to either a dealer or an indy that has a PIWIS to have the TPMS coded?

Would the swap to another set of wheels that are already coded to the truck need to happen again, from say the winter set to the spring/summer/fall set?

I don't think so. I think so long as they're sensors that are compatible with Porsche, you'd just do the usual "relearn" procedure... that IIRC is automatic. You'll get a popup on the DIC telling you the TPMS has to relearn. Drive a few miles and it should clear.

Anyone know where the TPMS control module is located on a 2011 Cayenne Turbo?
Thanks

The TPM control unit with integrated antenna is fitted on the outside on the vehicle underbody. The control unit is water-tight. The underbody panelling serves as mechanical protection for the control unit. The location of the control unit on the outside of the vehicle ensures that wheel electronics reception is not subject to interference as a result of various conditions in the passenger or luggage compartment or due to metallized heat-insulating glass.

Thank you!

True. If you purchase OEM/compatible sensors, the vehicle will pick them up automatically. I do this with my two sets of wheels/tires for summer and winter. I just input the change in rim size and tire type in the menu, then drive off.....before I'm at the end of my street they're set.

Exactly.. Being able to reset the TPMS is the one "gift" they give us DIY'ers. My wife's Subaru takes a $150 tool to do the same thing for the TPMS sensors, but no issues with an oil change indicator. Go figure!

Anyone know if it in the same place for a 08 957... Mine are being weird.. on off have to be reset all the time.

Might want to pose that question in the 957 forum...not sure how many members here also know the older platform...

Also, you might want to do some debugging before you start replacing modules... (error codes, battery and sensor age, etc...)

How long does the TPMS battery last? My 2021 Cayenne S is still in its original TPMS and works perfectly
