I recently acquired a 2012 Virage (my first AM) that has 2 bad TPMS sensors. The tires themselves are brand new so I assume that they were 1) damaged when the tires were installed, 2) the sensors were already dead and the PO / dealership I got the car from just didn't care or 3) there is a configuration step that was not done.

I have not been able to find a definitive statement about the process to install a new senor. Is AMDS required to configure a new sensor or should the system should "learn" a new sensor on start up? I got the car from a Porsche dealer so if configuration is required, it's possible that they just didn't have the ability to do the job.

Looking through the schematics the Virage has the LF antennas along with the front and rear antenna and I'm guessing that means it should configure automatically and that all I should need a new sensor.

Does someone out there have experience with this that they can say for sure how replacing a sensor works?

 

Replace all 4, they have a lifetime of 8 years. Self learning no programming necessary. Do a search been discussed by several and where to buy them from. Make sure you get the correct frequency for NA spec cars.

 

Thanks. Ordered a set of 4.

 

How were you able to tell which sensors were bad ? I have a 2011 and my TPMS light is on but the dash still shows a pressure reading for all 4 tires. Since this is the updated (not Smart Tire) system I cant find a way to fix it. The only thing I could think of is that the battery in one of the sensors is low which is why it still shows the pressure while still throwing a light.
Thanks

 

In my case they are completely dead and show as a warning triangle in 2 of the 4 wheel positions. Maybe like you say, yours has a low battery but is just not entirely dead yet.

I have a Foxwell scan tool that can talk to the control module and among other things it can read an estimated battery life for the sensors that are still communicating. There are also hand held wireless tools that can trigger the sensors individually and read them. Maybe a local tire shop has one of those and could read them for you.

 

They were installed new at the same time from build. Buy 4 install 4 and repeat every 8 years. Aftermarket sensors are readily available. You can have it repaired fairly easily at most tire shops.
