Figo Diesel ECU Error

I had similar engine performance issues with my 2014 Opel Astra, reduced power and ECU error codes. Did you check the voltage at the main relay? My problem was intermittent at first.

Thanks. What symptoms did you see with the Astra, and how did you confirm the main relay was the problem? I want to check other things before ECU repair.

The Astra had occasional power loss, especially during acceleration. Error codes pointed to generic ECU issues. After voltage tests and relay swapping, the intermittent voltage drop at the main relay confirmed it. I'd suggest a qualified workshop for diagnosis.

Thanks for the explanation. I took the Figo to a workshop, and they confirmed a defective relay. Total cost: 120€
