How to reset TPMS on a Porsche Cayenne Turbo
Recently Hometyre Milton Keynes attended a job in Loughton where a customer had a problem with his Porsche Cayenne Turbo that was not reading the rear tyre pressure sensors. The tyre pressure warning light was on and the on-screen display was showing the front tyre pressures but the rear tyre were not showing at all.
I started by scanning all the sensors to check that they were working and that the tyre pressures were correct. All sensors were found to be working and all tyre pressures correct. As the sensors are self-learning I decided to reset the connection between the Electronic Control Unit (ECU) and the sensors.
In order to do this you have to make sure that you are on the dashboard screen and not the SatNav screen. Using the arm below the indicator stick scroll through the menu screen until you come to the tyre options. Make sure you select the right tyres that are on the car - winter, summer or all season. Even if the correct one is selected unselect it and then reselect it. Check that the right tyre size is selected and if correct unselect and reselect it. Although this might seem a little tedious you should follow all the steps so that your ECU thinks that you have changed tyres and will reset the sensors once you take the car for a drive. You will need to stay above 20 miles an hour until the ECU resets - it shouldn't be more than 2 miles.
