Jetta Hybrid TPMS Warning Persists Despite Correct PSI

Had the same tire pressure sensor fault on my 2019 Passat GTE Hybrid last month. The air pressure readings were correct when checked with a pressure gauge, but the TPMS warning stayed on. The issue turned out to be a dying sensor battery in one of the wheels. These sensor batteries typically last 5-7 years before needing replacement. After proper diagnosis, it showed the front right sensor had completely lost communication with the control unit. The fix required replacing the faulty TPMS sensor. This is not a serious mechanical issue, but it needs attention since driving without working tire pressure monitoring can mask actual pressure problems later. For temporary troubleshooting: Double check tire pressure when tires are cold, Try resetting TPMS through vehicle menu, Watch if warning appears at specific speeds, Note if warning is constant or intermittent The sensor replacement process took about an hour since the tire needs to be dismounted to access the sensor. Would recommend getting this checked by a tire specialist who regularly deals with TPMS systems rather than a general mechanic.

Thanks for sharing your experience with the TPMS fault. I had a nearly identical issue with my 2016 Jetta last summer. After multiple tire pressure checks and TPMS resets, the warning light refused to turn off. Your post confirms what my tire specialist eventually found, a failing sensor battery. Question: Can you remember roughly how much they charged for the sensor replacement? Also, has your TPMS system stayed trouble-free since the repair? Just want to make sure no secondary issues popped up after fixing the initial sensor problem.

Had the repair done a few weeks ago and thankfully the TPMS system is working perfectly now. The tire pressure monitoring has been consistent with no false warnings since replacing the faulty sensor. When doing a tire check now, the readings show up correctly on the dashboard display. The total cost came to 280€ for diagnosing and fixing the sensor battery issue. This included dismounting the tire, installing the new sensor unit, and resetting the system. Getting a proper fix from a tire specialist was worth it, as driving with constant low tire warnings can make you miss real pressure problems. The repair shop also did a thorough pressure check on all tires and cleaned the air valve stems while they had everything apart. Makes sense since they had to handle the wheels anyway during the sensor replacement. My advice would be to get it done sooner rather than later. These sensor issues rarely fix themselves, and having reliable tire pressure monitoring is important for both safety and fuel economy.

Just wanted to update on my TPMS repair experience. Finally took my Jetta to a specialized tire shop rather than the previous mechanic. They quickly diagnosed a dead sensor battery in the rear left wheel, exactly as suggested here. The whole process took about 45 minutes. They replaced the faulty TPMS sensor, balanced the wheel, and reset the system. Cost was 265€ total, which included a full tire pressure check on all wheels. Much better experience than my last mechanic visit. The tire pressure warning disappeared immediately after the repair and hasnt come back in the past week. The dashboard now shows correct readings for all tires. Should have addressed this sooner instead of trying various resets and pressure adjustments. Really glad I found this forum thread before spending time and money on unnecessary fixes. The TPMS system is now working perfectly, giving accurate air pressure readings for all four tires.
