Seat Leon Turn Signal Problem

I had a similar issue with my Leon. The error message and the faulty lighting were quite annoying. The diagnostics indicated a problem with the electrical circuit related to the turn signal. Did you check the flasher relay?

Flasher relay? Where is that located? And how did you figure out it was an electrical fault?

The electrical fault was determined through a diagnostic scan at the workshop. As for the flasher relay, its location can vary, but it is often integrated within the vehicle's central electronic control unit. Given the error code and symptoms, a defective cable or plug connection is the most probable cause. It's likely best to consult a qualified technician to avoid further complications.

Took it to the workshop. It was a defective connection. 95€ and a new turn signal lamp later, everything is working again. Thanks for the help!
