Seat Arona lighting system fault

I'm experiencing a rather concerning issue with my 2019 Seat Arona diesel. With close to 178698 km on the clock, I've noticed a fault in the lighting system. The lights switch on, but I am receiving an error, and the error memory has logged this. Could a defective cable or plug connection of the component really be the cause?

Sounds familiar! I had a similar electrical problem with my Arona a while back. Did you check the fuse box? Sometimes a simple blown fuse can cause havoc with the dashboard lights and even the tail lights. Has the mechanic checked the car switch?

Thanks for the quick response! I did check the fuses, but they seemed fine. Where was the problem in your case? Was it also a faulty light switch, or something different?

In my situation, the whole electrical system was going nuts because of a defective car switch. Ultimately, I had to bring it to a workshop to get properly diagnosed. They found a short in the light switch wiring harness. Does that sound like what you might be experiencing? Given the error code, I suspect you should consider taking it to a mechanic. Do you have a multimeter to check the pins from the car switch?

I took it to the workshop as suggested and it turned out to be a faulty light switch cable. The repair cost 95€. Everything works fine now.
