Eseries reduced engine power

Sounds familiar. I had something similar happen in my Eseries (though it's an older model). Check your generator. When mine went bad, it threw a bunch of weird symptoms like that. Any work done recently, or did it just start happening?

Generator, huh? That's a thought. How did you know it was the generator and not something else, like the battery or serpentine belt? What symptoms did you have?

Well, the battery was new and the belt looked fine. Lights were dimming while driving, and the van barely started some mornings. The shop confirmed it was the generator. I would suggest to visit a workshop.

Thanks! I'll get the generator checked out. Sounds like that's the likely culprit. It ended up being a defective generator. Cost me 960€ to replace it. Appreciate the help!
