Skoda Yeti Battery Issues
Summary of the thread
A 2011 Skoda Yeti with a gasoline engine is experiencing battery issues, including heavy discharge, error messages in the speedometer, weak and flickering lights, and starting difficulties. The problem may be caused by a defective battery sensor, as suggested by similar experiences from others. The recommended solution is to have the vehicle's electrical system checked by a workshop, which confirmed the faulty sensor as the cause. Replacing the sensor resolved the issues.

Terminals look clean, and the battery is only two years old. But why would a bad battery cause error messages in the speedometer? That's what's really throwing me off.

Okay, if the terminals are clean and the battery is relatively new, it does sound like something more than just a simple dead battery. In my case, with the Megane, it turned out to be a faulty sensor draining the battery. The error messages are likely due to the electrical system freaking out because of the low voltage. I'd suggest getting it checked by a workshop; they can properly diagnose the electrical system.

You were right! The workshop confirmed it was the battery sensor. It cost 315€, but the discharged battery and error messages are gone. Thanks for the help!

Sounds like a discharged battery issue! I had something similar happen with my old Renault Megane. I kept getting a low battery warning and the lights would flicker. Have you checked the battery terminals for corrosion? Also, how old is your battery?
