The engine check light is on. Could you elaborate on the specific connections you inspected during your troubleshooting? Any particular areas prone to such issues on the C70?

Mine was a loose connection to one of the injectors. A mechanic found it pretty quick. It’s like a loose wire on a lamp – sometimes it works, sometimes it doesn’t. Honestly, I’d take it to a workshop; they’ll diagnose it properly.

I followed your advice and took the vehicle to a trusted workshop. The diagnosis confirmed a defective plug connection. The repair cost was 95€.

I had something similar happen with my C70. Fuel consumption went up, and it felt like I was driving with the parking brake on. Check all your connections, like the guy above said. It's often something simple. Is the check engine light on?
