Seat Leon Keyless Entry Failure

My Seat Leon (2013, Gasoline engine) keyless access has stopped working on the driver's door, and the car is throwing an error code. I suspect it's a wiring fault or a bad plug connection somewhere in the door electronics, maybe the door actuator. Has anyone else had this issue? What are your thoughts before I take it in? I'm trying to avoid a huge bill!

Sounds like a pain. Have you checked the door actuator itself? Sometimes they can get a bit wonky and cause sensor issues. Is it just one door, or are multiple doors affected? Does the central locking still work okay?

It's just the driver's side door. How would I check the door actuator, and could a dodgy actuator really kill the keyless entry? Central locking works fine from the key.

If it's just one door and the central locking is fine, it sounds like a localized issue within that door. A failing door actuator, or more likely the wiring harness or connector to it, could disable keyless entry. The sensor for that is probably integrated into the actuator. Honestly, tracing the wiring and testing the actuator properly needs diagnostic tools. If you aren't comfortable with that, a workshop visit is probably the best bet.

Spot on! A local mechanic found a faulty cable and plug connection to the door actuator. Cost me 95€, and now the keyless entry is working again. Thanks for the help!
