Crossland Tailgate Hall Sensor Fault

Hall sensor fault, eh? Those Crossland X tailgates can be a pain. Have you scoped the hall sensor signal itself? It could be a flaky sensor or an issue with the power supply to the sensor. Check the wiring diagram for the tailgate control module and see if there's a separate fuse for the tailgate. A voltage drop across a corroded fuse can cause all sorts of weirdness.

Thanks for the reply. I haven't scoped the signal yet, but that's next on my list. Do you know if a sensor calibration is required after replacement, or is it usually plug-and-play? I was hoping to avoid a trip to the dealership for recalibration.

Calibration isn't always strictly required, but it's best practice, especially with power tailgates. Given it's a hall sensor fault and the tailgate isn't fully opening, there's a good chance the sensor's output range is off, and the BCM (Body Control Module) is misinterpreting the tailgate position. However, considering it's intermittent and you've checked the basics, and to be absolutely certain, it would be best to visit a workshop that specializes in car electronics.

Appreciate the advice. I ended up taking it to a local independent garage. Turns out it was a corroded connector on the hall sensor itself, as suspected. They cleaned it up, re-seated it, and cleared the fault code. Cost me 95€, a worthwhile price to avoid further headaches.
