I have passo 2012. The engine light switched one and ECO light was gone and consumption drastically reduced and car started taking jurks. I removed the battery terminal and it was gone but after few hours it appered again
Take it to a mechanic and hook it up with the computer to see what are the error codes. Then search the codes online to narrow down your problem. That would be the best way to search and narrow down your problem list.
