Thanks for the tip! Which relay was it specifically? And did you notice any other weird symptoms before it went completely?

It was the main relay, and no, I didn't notice anything else beforehand. It just happened suddenly one day. If replacing it doesn't fix the problem, I'd suggest taking it to a workshop to get the ECU properly checked.

Thanks again! Indeed, main relay was faulty. I replaced it and the error is gone and the engine runs smoothly. The repair cost me 120€. Saved me a lot of headache!

Hey, I had something similar happen with my ix35. Reduced power and an ECU error. Have you checked the relays? That was the source of the issue in my case. It's worth looking into before anything else.
