Skoda Kodiaq Battery Issues

Sounds familiar. I had similar issues with my Kodiaq weak starts, lights flickering at idle. Have you checked the battery voltage with vehicle diagnostics? Could be a faulty voltage sensor messing with the battery charge.

Vehicle diagnostics? Where do I check that? And how would a voltage sensor cause all this? I thought the battery health was just about the battery itself.

Vehicle diagnostics through an OBD reader, you can get cheap ones online. The voltage sensor tells the car how much to charge the battery. If it's faulty, it might not be charging it properly, leading to low battery voltage and those symptoms. I ended up having mine replaced, and it solved the problem, so I would suggest that you get it checked out by a workshop.

Thanks for the help! The workshop confirmed the battery sensor was faulty. The repair cost 315€. Hopefully, this fixes the issue.
