S80 Reduced Engine Power

I had almost the exact same symptoms on my S80! Reduced power, warning lights, the works. Have you checked the voltage regulator on the generator?

Thanks! I haven't checked the voltage regulator specifically, but I was leaning towards replacing the entire generator. Was it definitely the voltage regulator in your case, or did you end up replacing the whole thing?

For me, it was easier and safer just to get the whole generator replaced. Save yourself the trouble and go to a workshop. Good luck!

Okay, good to know. I think I’ll take it to a workshop then, and have them check the generator. Thanks so much for sharing your experience; it's really helpful! I will let you know about the repair costs; I think it might be around 960€.
