XC70 tailgate hall sensor issue

Hey there! I have an XC70 as well, and your issue sounds awfully familiar. My power tailgate was acting up similarly. A hall sensor is an electrical sensor that detects the proximity of something, often using magnetism. Have you checked the wiring and connections to the sensor in the tailgate? Sometimes a loose or corroded connection can cause these kinds of problems. Also, did you try any sensor calibration?

Thanks for the reply! I checked the connections visually, but didn't see anything obvious. What exactly do you mean by 'sensor calibration'? Is there a procedure I can follow?

Okay, so by calibration I mean that the sensor might need to be 'taught' the correct positions again, but honestly, in my case, the visual inspection also didn't reveal anything at first glance. It turned out the cable was internally damaged, so it wasn't easy to spot. To be honest, I'd suggest taking it to a workshop; they have the right tools to properly diagnose electrical issues and can check the sensor and wiring thoroughly.

Thanks for the advice. I took it to a shop, and you were right – it was indeed a damaged cable. They replaced it, and also the plug to the sensor because it was corroded as well. Total cost was 95€ including labor. Everything works fine now!
