Stubborn Audi S4 TPMS Warning Won't Clear After Reset

Had the same sensor fault issue on my 2017 Audi A5 2.0 TFSI. The tire pressure warning kept appearing despite correct inflation levels. Initially thought it was just a simple air valve problem, but diagnostic testing revealed dead TPMS sensor batteries in two wheels. These sensors typically last 5-7 years before battery replacement becomes necessary. When they start failing, they often trigger false low pressure readings and persistent warning messages that wont clear through normal reset procedures. The fix required replacing all four TPMS sensors since they were all nearing end of life. This prevents dealing with the same issue wheel by wheel over the next months. Not a serious mechanical problem, but definitely requires proper attention since driving with non-functional TPMS means missing actual flat tire situations. The repair process involves: TPMS diagnostic scan, Removing tires from wheels, Installing new sensors, Programming sensors to vehicle, Tire remounting and balancing Worth noting that attempting temporary fixes like continuous resets or ignoring the warning only masks the underlying sensor fault. Best to address all sensors at once for a complete solution.

Thanks for sharing your experience. Similar problems with my S4 last winter. The tire pressure warning drove me crazy and regular checks with a pressure gauge showed everything was fine. Finally got all sensors replaced since they were original and way past their expected lifespan. Quick question, do you remember the total cost for your sensor replacement? Also curious if youve had any more TPMS alerts since getting the new sensors installed. The repair has been solid for me but always good to hear long-term feedback from others who had the same fix.

After getting the new sensor battery replaced, my TPMS system has been working flawlessly. The tire pressure monitoring is back to normal with no false alerts or sensor faults. The repair cost was 280 Euro for parts and labor, which included a full system diagnostic to ensure proper TPMS functionality. Based on my experience, once the dead sensor battery was replaced, all tire pressure readings became accurate and reliable again. Regular tire checks now show consistent pressure values matching the dashboard display. Its been a worthwhile fix that solved the issue completely, eliminating those frustrating false warning messages. The key was addressing the sensor fault promptly rather than continuing to deal with unreliable readings. A properly functioning TPMS system is essential for catching actual low tire situations before they become problematic.

After getting the repair done at my usual shop, I can confirm the TPMS issue is completely resolved. Total cost came to 320 Euro for replacing all sensors, bit more than expected but worth it to fix the sensor fault permanently. My mechanic showed me the old sensors and the batteries were definitely shot after 8 years. Now my pressure gauge readings match the dashboard display perfectly. No more false alarms or fighting with that annoying tire pressure warning light. Just did a long drive yesterday and everything worked great, the system caught a slightly low tire that I was able to top up right away. The fix turned out to be exactly what was needed. Good to hear your repair has held up well too. Seems like a common issue once these TPMS sensors get old, but at least its a straightforward replacement job when done right.
