Skoda Octavia Headlight Range Control Issue
Summary of the thread
A 2004 Skoda Octavia is experiencing a headlight range control issue, with the warning light on and low beams misaligned. The problem is suspected to be a defective servomotor in the headlight unit. Suggested solutions include checking the headlight switch, inspecting electrical connectors for corrosion or loose connections, and considering professional diagnosis. Ultimately, the issue was confirmed to be a defective servomotor, which was resolved at a workshop.

Interesting. So, when you say check the electrical connectors, what exactly am I looking for? Is there a specific way to test them, or is it more of a visual inspection type of thing?

Yep, visual inspection mostly. Look for any signs of corrosion – that green or white powdery stuff. Also, check if the connectors are properly seated. Give the wires a gentle tug to see if any are loose. If you have a multimeter, you could check for voltage at the connector when the headlights are switched on, but honestly, unless you're comfortable with electrical testing, I'd probably just take it to a workshop at this point. Given the symptoms and the error code, a defective servomotor is a strong possibility, and they'll be able to diagnose it properly. It could also be related to the auto-leveling system's sensors, but a workshop will be able to pinpoint the exact cause.

Took the Octavia to the shop as you suggested. It was indeed a defective servomotor in the headlight unit, just as you suspected. The whole thing cost me around 1040€ to get fixed. Thanks a lot for your help and pointing me in the right direction!

Headlight malfunction, eh? Sounds like a pain. I had a similar issue with my old Peugeot 307. The auto-leveling went haywire. First thing I'd check, and this might sound obvious, is the headlight switch itself. Sometimes a dodgy switch can cause all sorts of weird electrical problems. Then, have you had a look at the electrical connectors going to the headlights? Give them a wiggle, see if anything changes. Could be a loose connection or corrosion causing the trouble. But yeah, if the low beam is shining all over the place, it does sound like the servomotor is suspect.
