VW Polo Tailgate Sensor Fault Disrupts Auto-Opening

Having experienced this exact issue on my 2011 VW Golf TDI, the power tailgate problem was related to faulty vehicle sensor connections rather than a complete motor failure. The hall sensor fault typically indicates either corroded wiring or a deteriorated sensor calibration module. In my case, the electrical sensor harness near the tailgate hinge had worn through from repeated opening and closing movements, causing intermittent operation. The repair involved: Testing the sensor wiring continuity, Replacing the damaged wire harness section, Performing sensor calibration after installation, Verifying proper tailgate operation through multiple cycles This is generally not a serious repair when caught early, but leaving it unaddressed can lead to increased strain on the motor and more extensive damage. The key is proper diagnosis of whether its truly a sensor issue versus mechanical binding or motor problems. Important: Having this diagnosed by someone familiar with VW power tailgate systems is crucial, as improper repairs can damage the control module. The vehicle sensor system needs specific diagnostic equipment to properly reset and calibrate after repairs.

Thanks for sharing that info about the automatic tailgate sensor fix. Had the same problem with my VW too, really frustrating when the open tailgate function just stops working properly. Getting an electrical sensor replaced fixed it for me. Did you keep track of the repair costs? Also curious if youve had any other sensor fault issues since the fix? Would help to know if its a lasting solution.

Thanks for asking about the follow-up experience. After getting it fixed, I can confirm the power tailgate has worked flawlessly. The hall sensor fault was resolved by repairing a faulty cable connection, which cost 95€ for parts and labor. The repair shop found the wiring had become loose near the hinge area. Since the sensor calibration was properly done after fixing the connection, I have not experienced any new sensor fault codes or issues with the open tailgate function. The automatic operation is now as smooth as when the car was new. This type of repair tends to be a permanent solution as long as the wiring is properly secured to prevent future wear. Just make sure any repair includes proper sensor calibration after the work is complete.

Had the issue checked out today at my usual shop. The mechanic found worn wiring near the tailgate hinge, just like you mentioned. Total repair came to 110€ including new wiring and sensor calibration work. The automatic tailgate is working perfectly now, opens and closes like new. Really glad I asked here first since it helped me understand the vehicle sensor issue. Saved me from getting sold on replacing the whole motor unit. They also checked the other electrical sensors while doing the work and everything else tested fine. The mechanic showed me where the original wiring had worn through, which caused the hall sensor fault codes. No other issues since the fix was done. Thanks again for the guidance. Having that knowledge beforehand made me more confident about getting the right repair done.
