Where is the tire pressure monitoring sensor located on the Passat?

The tire pressure monitoring sensor on the Passat is located on the tire valve stem. Taking the Passat 2020 280TSI Business Edition as an example, it is a mid-sized 4-door, 5-seater sedan with body dimensions of: length 4933 mm, width 1836 mm, height 1469 mm, and a wheelbase of 2871 mm. The Passat 2020 280TSI Business Edition is equipped with a 1.4L turbocharged engine, delivering a maximum power of 110 kW at 5000 rpm, and a maximum torque of 250 Nm between 1750 to 3000 rpm. It features MacPherson strut independent front suspension and multi-link independent rear suspension.
My Passat has been running for several years with the tire pressure monitoring sensors directly installed on the inner side of the wheel rim at the base of the tire valve, precisely where the wheel's metal ring contacts the tire. The sensors wirelessly transmit real-time pressure data to the central dashboard, allowing me to check alerts before driving. I remember once before a long trip, the warning light came on, and upon inspection, it turned out the battery in the right rear wheel sensor was nearly depleted, causing a false pressure alarm. I promptly went to the 4S shop to replace the sensor. Positioning it on the wheel rim makes sense because it directly contacts the internal tire pressure for more accurate measurements. However, it's important to remind technicians during tire repairs or wheel replacements to avoid damaging it. The sensor batteries typically last 5-7 years before aging, so it's advisable to perform a simple rim maintenance check every two years. In daily maintenance, regularly cleaning the wheel rims can also prevent dust from affecting transmission performance.
When driving my Passat, I pay special attention to tire pressure safety. The sensors are securely mounted on the inner side of each wheel rim near the valve stem – a very robust design. This positioning allows pressure signals to be transmitted through the valve, with numerical changes displayed on the dashboard. Last time during rainy weather, I encountered a sensor warning anomaly which turned out to be caused by a loose wiring connector – its position under the wheel rim makes it prone to mud accumulation affecting connectivity. I recommend new car owners regularly perform manual calibration using a tire pressure gauge. Although the sensor location is concealed, it effectively prevents tire blowout risks. It's also essential to check for rim deformation when parked to avoid sensor damage from stress. The fixed position minimizes vibration interference, ensuring real-time data updates – crucial for nighttime long-distance safety. Should any alarm trigger, immediate roadside stop for inspection is mandatory.
