I've seen similar Aygo issues. Any voltage drops or battery drainage? Check the battery and generator connections. Does the starter sound normal or sluggish?

I haven't measured voltage drops, but the battery drains fast when idle. The starter sounds a bit labored. Does this confirm a generator fault?

Sounds like a generator issue. I had similar symptoms and needed a replacement. Get a technician to assess it, but replacement is likely needed.

I took it to a workshop. They confirmed the generator was defective. The repair was 960€. It's working now.
