Audi Q3's Stuck Tailgate Frustrates Owner, Fix Needed

My 2012 Audi Q5 2.0 TFSI had similar power tailgate issues. The automatic function would stop midway, showing an error message on the display. After inspection, the main problem was traced to a faulty hall sensor connection near the tailgate motor. The repair involved testing the electrical sensor connectivity and replacing corroded wiring harness components. The vehicle sensor system was showing incorrect position readings, causing the tailgate to stop unexpectedly. The fix required dismantling the tailgate panel to access the wiring and sensor assembly. The root cause turned out to be water penetration that damaged the sensor connections over time. This is a known issue that can affect the power tailgate functionality. The repair was relatively straightforward but required specialized diagnostic equipment to properly calibrate the new hall sensor after installation. Despite initial concerns about a complete motor replacement, the actual fix focused on the sensor fault and wiring. It was not a serious mechanical issue, though leaving it unrepaired could lead to more significant problems with the tailgate mechanism. The repair shop needed about 3 hours to complete the work, including testing and calibration of the power tailgate system.

Thanks for sharing your experience. I had exactly the same hall sensor issue with my Q3 last year. The automatic tailgate would stop out of nowhere and eventually stopped working completely. Your description matches what I experienced, especially about the water damage causing sensor connectivity problems. Did you remember roughly how much you paid for the complete repair? Also, has the tailgate system been working properly since the fix, or have you noticed any other electrical sensor issues? Just wondering because after my repair, I noticed the tailgate occasionally needs a second press to open fully, though its much better than before.

Yes, got my vehicle sensor issue fixed last week. Paid 95 Euro for repairing a faulty cable connection near the hall sensor. The mechanic confirmed water damage had corroded the wiring, similar to your case. The automatic tailgate now works flawlessly, opens and closes fully without needing multiple button presses. The power tailgate system reacts immediately when activated. Unlike your experience, I have not noticed any hesitation or need for second attempts. The sensor fault has been completely resolved, and the diagnostic system shows no more error codes. Definitely worth getting it properly fixed rather than living with a partially functioning system that could lead to bigger issues later. My advice would be to have your tailgate checked again since requiring a second press suggests the hall sensor calibration might need adjustment. Small issues like this can sometimes indicate the start of new connection problems.

Thanks for the advice. After reading about similar experiences, I finally got my Q3 fixed at a different workshop. The hall sensor replacement and rewiring cost me 180 Euro total, including labor. The mechanic showed me the corroded wiring and damaged sensor components they removed. The automatic tailgate now works perfectly, opens and closes smoothly in one go. No more error messages or partial opening issues. They also applied additional water protection around the sensor area to prevent future damage. The whole repair took about 2 hours, and they tested the power tailgate system thoroughly before returning the car. Really glad I switched mechanics. The new shop diagnosed the sensor fault quickly and fixed it right the first time. Much better experience than my previous attempts to get this resolved.
