Scenic Overvoltage Faults

I had a similar issue with my Scenic. Lots of weird electrical faults popping up. Have you checked your voltage regulator? That was the culprit in my case.

Thanks. What symptoms did you have, and how did you figure out it was the voltage regulator?

The symptoms were very similar: random electrical failures and the battery struggled, especially on cold starts. I took it to a workshop, and they found the faulty voltage regulator. Have it checked by a professional.

I appreciate the advice. I'll get the voltage regulator checked. The issue was solved. The battery was defective and had to be replaced. Also, the circuit protection was renewed. The repair cost 290€.
