Persistent TPMS Warning Despite Normal Tire Pressure

Had the same TPMS issue on my 2011 VW Tiguan 1.4 TSI. After multiple tire pressure checks and basic sensor diagnostics, the root cause turned out to be failing sensor batteries. The constant low tire warnings appeared even though air pressure was correct. The sensor batteries typically last 5-8 years, and at that age they start sending irregular signals. All four TPMS sensors needed replacement since they were original equipment. Not a serious mechanical issue, but critical for accurate tire monitoring. The fix requires installing new TPMS sensors followed by proper programming to sync with the car computer. After replacement, the system needs a specific relearn procedure while driving. The low tire warnings disappeared completely after this repair. Most workshops first try resetting or reprogramming existing sensors to save costs, but with sensors this age, replacement is often the only reliable solution. Make sure your workshop specializes in VW diagnostic systems, as proper TPMS programming is brand-specific.

Thanks for sharing your experience with the sensor fault. I faced nearly identical TPMS problems with my VW Touran. After getting the tire pressure checked repeatedly with no success, replacing all sensors finally solved it. The warning lights have stayed off for 6 months now. Would you mind sharing what the sensor replacement ended up costing? I paid around 380€ total, but prices seem to vary quite a bit. Also curious if you had any air valve issues or other TPMS-related problems since the repair?

Good to hear the sensor replacement worked for you too. The flat tire warnings and TPMS issues can be really frustrating when the air pressure is actually fine. After visiting my mechanic last month, replacing the failing sensor batteries fixed the problem completely. The total cost came to 280€ including programming, which seems reasonable compared to your price. Since having the tire pressure monitoring system repaired, all sensors are working perfectly with no false low tire alerts or valve problems. The constant fault messages have stopped entirely. Proper TPMS function really gives peace of mind when driving, knowing youll get accurate warnings if there actually is a pressure issue. If other owners experience similar sensor problems, getting the batteries checked should be the first step once the tires are confirmed to be properly inflated. Much better to address failing sensors early before they cause more extensive TPMS system issues.

Finally found a reliable mechanic who properly diagnosed and fixed my TPMS issue. Had all sensors replaced for 380€ at a certified VW workshop rather than the previous places that just kept resetting the system. The tire pressure monitoring now works flawlessly, no more unusual warning lights even after a thorough tire check. The mechanic showed me the old sensors and explained how the battery degradation was causing the false readings. Much better service than the previous attempts at quick fixes. They also performed a complete air pressure check and TPMS calibration after installation. Its been 6 months of trouble-free driving with accurate tire monitoring. Worth every cent compared to the constant headache of unreliable sensors. Will definitely stick with this workshop for future repairs since they actually found and fixed the root cause rather than just treating symptoms. Just wanted to close the loop here for others who might face similar TPMS problems. Sometimes paying a bit more for proper diagnosis and repair at a specialized shop saves money and frustration in the long run.
