The reasons why the Touareg tire pressure monitoring does not display are: 1. The tire pressure is too high, check if there is a warning light on the dashboard; 2. You can release some air and check again. If it still does not display, the built-in tire pressure detection module may be faulty. Taking the 2020 Touareg as an example, it belongs to the mid-size SUV category, with body dimensions of: length 4878mm, width 1984mm, height 1686mm, wheelbase 2899mm, and a fuel tank capacity of 90l. The 2020 Touareg is equipped with a 2.0T turbocharged engine, with a maximum horsepower of 245PS, maximum power of 180kW, maximum torque of 370Nm, and is paired with an 8-speed automatic transmission.
Once when driving a friend's Touareg, I encountered an issue where the tire pressure wasn't displaying. It was most likely due to the sensor battery running out of power. The lifespan of the coin cell battery inside the tire pressure monitoring sensor is approximately 5-7 years, and this problem is particularly common in older vehicles. Additionally, the data won't display if the system isn't reset after tire rotation or patching, in which case you'll need to relearn and match it through the central control screen. I've also seen cases where the module connector became loose, especially the receiver module connector on the side of the trunk, which can easily get jostled loose. The most troublesome scenario is when the sensor gets damaged by the tire repair technician. Last year when I had a tire patched, I repeatedly reminded them to be careful during disassembly and installation. My suggestion is to try replacing the sensor first, as it's the most frequent culprit.
The lack of tire pressure display in the Touareg is most likely related to signal reception issues. Sensor failure is the most common cause, with depleted batteries or aged components potentially preventing signal transmission. The signal reception module is hidden behind the left trim panel in the trunk, and water damage or corroded wiring can also cause malfunctions. Some vehicles with aftermarket central control screens may experience compatibility issues - I've seen cases where installing 360-degree cameras caused signal interference. Additionally, if the wheel positions aren't reset after tire rotation, the vehicle won't recognize signals from new positions. The troubleshooting sequence should be: first check for warning lights on the dashboard, then use a diagnostic tool to read fault codes - this can save significant guesswork time.
