VW Arteon Power Tailgate Malfunction: Halfway Lift Error

Had the same tailgate motor issue on my 2020 Passat GT. The power tailgate would stop midway and flash errors on the dash. The root cause was a faulty hall sensor that monitors the tailgate position. The repair involved testing the wiring harness connections first, since loose plugs can trigger similar symptoms. When that checked out fine, diagnostic tests confirmed the hall sensor had failed. These sensors need precise calibration after replacement to ensure proper opening height and speed control. This is actually a common fault that develops on these models. Once the new sensor was installed and calibrated, the power tailgate system worked perfectly again. The repair took about 2 hours at the shop. Worth checking if there are any software updates available for your tailgate control module before replacing parts. Sometimes a simple reset and recalibration can resolve sensor faults without needing new components. The issue is not severe in terms of vehicle safety, but should be addressed to prevent potential damage to the tailgate mechanism from improper operation.

Thanks for sharing your experience with the hall sensor replacement. The symptoms you described match exactly what I am seeing with my Arteon. It is good to know the repair went smoothly for you. Can you remember roughly how much you paid for the sensor replacement and calibration work? Also, has everything been working properly since the fix or have you noticed any other electrical sensor issues with the power tailgate? My local VW dealer quoted a pretty high price so I am trying to get a sense of what others paid for similar repairs. The vehicle sensor problems are really frustrating considering how new the car is.

Good to hear my experience helped. I just got back from having this exact issue fixed. The automatic tailgate works perfectly now after they repaired a loose connection in the sensor wiring. Total cost was 95€ for the repair, which was much less than expected since they only needed to fix the cable connection rather than replace the entire hall sensor. The repair shop found the hall sensor itself was fine, just had a defective plug connection that was causing the position readings to fail. Since they fixed it last week, the tailgate operation has been flawless with no error messages. Much cheaper solution than the full sensor replacement I initially thought would be needed. If your symptoms are identical, might be worth having them check the sensor wiring and connections first before committing to a complete sensor replacement. Sometimes these sensor calibration issues can be resolved with simple electrical repairs rather than installing new components. The automatic tailgate system is quite sensitive to any wiring problems, but once properly fixed it should give you reliable service. Getting it diagnosed early helps prevent additional wear on the tailgate motor from improper operation.

Just got back from the repair shop with good news. After checking the power tailgate system, they found the same wiring issue you mentioned. The automatic tailgate sensor had a loose connection that was causing the erratic behavior. Total repair cost came to 120€ which included testing, fixing the sensor wiring, and recalibrating the system. Much better than the 450€ the dealer wanted for a full sensor replacement. The vehicle sensor is now working perfectly and the trunk opens smoothly without any error messages. Really glad I asked here first before going straight for the expensive repair at the dealer. The shop also checked all the other tailgate connections while they had it open, so hopefully this prevents any future issues. Thanks again for pointing me in the right direction with the wiring check suggestion.
