Faulty TPMS Giving False Low Pressure Alerts in VW Virtus

My TPMS sensor keeps showing low tire pressure despite proper inflation. Checked all air valves and they seem fine, but the warning light wont go away and theres an error code stored. Had a bad experience with my local mechanic last time and looking for advice before going back. Anyone dealt with similar tire pressure sensor faults? Car details: 2020 VW Virtus, gasoline engine, 78863

As a VW ID.4 (2017) owner, I faced this exact TPMS issue last season. The symptoms were identical, persistent low tire pressure warnings despite correct tire inflation levels. The problem wasnt actually tire related, but rather a failing TPMS sensor battery in one wheel. These sensor batteries typically last 5-7 years before requiring replacement. When they start failing, they send incorrect signals to the control module, triggering false low tire warnings. The stored error code is usually a clear indication of sensor battery depletion rather than an actual tire pressure problem. The fix required replacing the aging sensor unit completely, as TPMS sensor batteries arent serviceable separately. Its not a serious mechanical issue, but it does need addressing since a non-functioning TPMS system means you wont get accurate tire pressure warnings when you actually need them. The repair process involved: Diagnostic scan to identify the specific failing sensor, Tire removal from the wheel, Old sensor replacement, System relearn procedure, Final diagnostic check Consider having all sensors checked while the car is being serviced, as the others might be approaching their end of life too, given the age of your Virtus.

Thanks for sharing your experience with the TPMS sensor issue. My Virtus started showing the same symptoms this week, and your explanation really helped me understand whats going on. It makes sense about the sensor batteries having a limited lifespan. Planning to get it fixed this weekend. Would you remember roughly how much you paid for the repair? Also, has the new sensor been working properly since the replacement, or have you noticed any other tire pressure monitoring issues? The local shop quoted me 85€ per sensor, which seemed high, but maybe thats standard for VW TPMS parts. Just want to make sure Im not overpaying.

Just had to update on my TPMS repair from last week. The new sensor is working perfectly with no more false low tire pressure warnings. The repair cost came to 280€ total, including labor and the sensor replacement. While it might seem steep, quality TPMS sensors for VW models do run on the higher end of the price scale. Your quoted price of 85€ per sensor actually sounds reasonable, its in line with what I paid. The rest was labor costs since they needed to dismount the tire, replace the sensor, and perform the system relearn procedure. Worth noting that my ID.4s TPMS system has been flawless since the fix, giving accurate tire pressure readings. Getting it fixed was definitely the right choice, as a malfunctioning TPMS system cant alert you to genuine tire inflation issues when they occur. If youre still shopping around, those prices youve been quoted are pretty standard for VW sensor replacements.

I took your advice and got the TPMS sensor replaced yesterday. The repair went smoothly and the total cost was 295€, including the new sensor, labor, and system programming. Pretty close to what you paid. The mechanic confirmed exactly what you mentioned, the original sensor battery was failing. While they had the tire off, they did a thorough tire check and found no other issues. The pressure gauge readings were all normal, just as I suspected. The TPMS warning light finally cleared after they completed the system relearn. Been driving for 24 hours now with no false low tire alerts. The service advisor suggested monitoring the other sensors over the next few months since they're all the same age. Much better experience this time compared to my last visit. Thanks for helping me understand the issue before going in. Saved me from getting unnecessary additional repairs suggested.
