While anything is possible with enough money - in this case - the money spent to do this would seem excessive to me. Problem is - as with almost all German cars - if an option wasn't spec'd when the vehicle is built - the wiring for it simply isn't there. And it's not simple to add the wiring since it's usually part of another harness, which may wander throughout the vehicle. The factory system (from memory) has 4 antennas - one for each wheel, located behind the wheel well liners. There is likely a control unit also. Adding this much equipment, then creating a custom wiring harness to make it all work, and enabling the function in the Gateway/ECU - would likely run into the several thousands of dollars range.


There are systems made for aftermarket installation. They typically use a small display, requiring 12V power/ground, and 4 RF equipped wheel sensors. Cost is more in the $100-200 range for these. Problem is - where to put the display where it would be visible but not intrusive. I'd have to sit in mine to come up with an answer for that..


This propensity of the Germans to never add an unused wire is probably ecologically sound practice, and even engineering sound practice - but it does make retrofitting anything to a vehicle a really expensive chore if you want to go with OE equipment.

Hi Everybody, Does anyone Know if is posible to install Tire Pressure Monitoring System on a Cayenne that didn't come with that. I mean the original system.



Just out of curiosity why would you want to do this? I check my tires regularly even though all 5 vehicles have TPMS. Just another hassle after 8 years or so when the batteries go bad.
