S90 Hybrid Engine Overheating

Interesting. I had a similar issue with my old BMW 3 series. Engine was overheating like crazy. Have you checked the fan's fuse? In my case, that was the culprit.

Thank you. I hadn't considered the fuse. Could you tell me where the fuse and relay are located, and what electrical tests you did?

Honestly, I am not too savvy on that stuff. I just took it to my local mechanic, and he figured it out pretty quick. Might be your best bet rather than messing something else up.

I appreciate the advice. I scheduled an appointment at the repair workshop. It was a defective plug connection, and the repair cost 95€.
