VW Nivus TPMS Sensor Malfunction Fix & Repair Guide

Having some experience with VW sensor systems, I dealt with an identical issue on my 2021 VW T-Cross. The tire pressure monitoring system kept showing low tire warnings despite correct tire inflation levels. After multiple tire checks, the workshop diagnosed a dying sensor battery in one of the TPMS sensors. These sensors are integrated into the valve stems and communicate wirelessly with the car's computer. The constant false warnings are a typical symptom of sensor battery depletion. The repair involved replacing the faulty sensor, reprogramming the new one, and clearing the stored error codes. Total cost was 280€, including parts and labor. Since the fix, the system has worked flawlessly with no more false low tire warnings. To help troubleshoot your case more accurately, could you share: Whether all tires trigger the warning or just specific ones, If the sensor fault appears immediately after starting the car, When the last time was the tires were serviced or replaced, If the warnings started gradually or suddenly This information would help determine if you are facing the same sensor battery issue or possibly a different TPMS problem.

Had my first service at 15000km just last month, currently at 18715km. Thanks for the detailed response about the sensor issue. In my case, the TPMS issue seems isolated to the front right tire. The air pressure warning appears about 5-10 minutes into each drive, not immediately at startup. I double-checked the air valve and pressure again yesterday, all tires are properly inflated to spec (2.5 bar). The warnings started appearing suddenly last week, no gradual onset. The tire itself shows no signs of slow leaks or damage. Getting concerned about potential sensor malfunction, especially since this is still a relatively new vehicle. Looks like I might be facing a similar sensor battery problem. Going to schedule a diagnostic check based on your experience. The 280€ repair cost gives me a good reference point for what to expect.

Thanks for those additional details. Given the symptoms you described, especially the delayed warning onset and single tire focus, it does sound nearly identical to what I encountered with my T-Cross TPMS sensor. The timing of the warning appearing 5-10 minutes into drives is particularly telling. This behavior typically indicates the sensor is struggling to maintain consistent communication with the car's computer, a common sign of low sensor battery voltage. One key difference from my case, your vehicle being much newer with only 18715km should technically still have plenty of sensor battery life left. While sensor batteries usually last 5-7 years, occasional premature failures do occur. Since your flat tire warning is isolated to just the front right position despite proper tire inflation, the sensor itself is likely defective rather than just depleted. Under warranty, this repair should be covered at no cost, unlike the 280€ I had to pay for my out-of-warranty T-Cross. Would strongly recommend having the dealer check the specific sensor, as they can verify if its a factory defect. While waiting for the appointment, continue monitoring the tire pressure manually, but the intermittent TPMS issue itself shouldnt affect vehicle safety as long as you maintain proper tire inflation levels.

The sensor fault diagnosis makes a lot of sense. After monitoring the tire pressure myself several more times this week with a pressure gauge, I'm convinced it must be a defective TPMS sensor causing these false warnings. Called the dealer service department and explained the symptoms, the delayed warning activation, the single tire focus, and confirmed proper air pressure readings. They agreed it sounds like a faulty front right tire pressure sensor. Since the car is still under warranty, they will diagnose and replace the sensor at no cost if defective. Have an appointment scheduled for next week. Will keep manually checking the tire pressure until then just to be safe, but feeling better knowing this is likely just a sensor issue rather than an actual flat tire problem. Really helpful to hear about your similar experience with the TPMS sensors. The detailed information about sensor battery behavior and typical repair costs gave me a clear picture of what to expect. Glad I can get this resolved under warranty instead of paying the 280€ out-of-pocket cost.
