Hello, The car in question is a Skoda Octavia 4x4 2009. I've recently had this issue where I get a warning on my dashboard saying the right daytime running light is not working, but it is working. The issue seems to appear when there's alot of moisture in the air, fog etc. I have previously had issues with this particular light, I had to frequently tap the headlight to get the light working, replaced the bulb multiple times. What i've done so far: I've replaced the bulb. Cleaned the connector plate inside the headlight where the bulb connects. Checked the wires inside the headlight. Swapped the entire headlights from left to right side and still get the right side is not working when it's the actual left headlight connected, which indicates that the issue is not in the headlight itself. Do you have any ideas as to where the root cause of this issue might be and how to fix it?
