Interesting, thanks for the advice! Where exactly should I look for these cable connections? Are they easy to get to, or do I need to remove other parts first? Also, what should I be looking for, corrosion or loose connections?

The cable connections are located directly on the battery terminals. Check for any signs of corrosion, which will appear as a white or bluish deposit. Also, ensure the connections are tight; you should not be able to move them by hand. If the problem persists, I would suggest a visit to a qualified workshop. It could point to an ECU failure.

Just wanted to let you know. You were spot on! It was indeed a loose connection on the battery cable. Cleaned it up, tightened everything, and now it starts like a charm. Cost me 155€ at the repair shop. Thanks a lot for your help!

I had a similar problem with my Prius – though mine's a newer model. The engine light came on, and it wouldn't start. Have you checked the cable connections to the battery? A loose or corroded connection can cause all sorts of weird electrical issues that trigger the engine control malfunction.
