WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.

The remaining service life of the wheel electronics can be read out with the Porsche System Tester. Before scheduled maintenance and/or changing a tyre, it is recommended to read out the remaining service life of the wheel electronics (due to battery capacity). It is always advisable to replace the wheel electronics if the expected remaining service life of the wheel electronics is shorter than that of the tyre. The battery for the wheel electronics cannot be replaced separately.

Connect the -Porsche System Tester- . Read out the respective battery service life of the wheel electronics, FL, FR, RL, RR in months in the menu >> RDK >> Actual values >> Battery service life <<.
