Seat Formentor Hybrid Tailgate Problem

Sounds like a faulty tailgate hall sensor. I had a similar issue with my Formentor. Check the sensor wiring to the tailgate motor first. Could be a loose plug connection.

Thanks for the quick reply! When you say 'sensor wiring', are you referring to the vehicle sensor that detects if something is blocking the open tailgate, or something else entirely? Is there an easy way to check the plug connection, or is it buried deep?

Yeah, I meant the vehicle sensor that controls the open tailgate. The plug connection can be a pain to get to, buried behind some trim. If you aren't comfortable poking around, I'd just take it in. It was the sensor wiring in my case, and the garage sorted it quickly.

Took it to the workshop, and you were spot on. It was indeed a defective sensor wiring in the automatic tailgate. 95€ later, and the tailgate is working perfectly again. Thanks for your help!
