Chosen Solution
So, I have a VW Passat B6 2007. My rear right side tail light, day time running light stays on for a few seconds before it turns off. Now I don’t find the solution, and trust me I have tried. When turned on it starts to blink and then it turns off, I tried to put 12V directly on to the light and it worked perfectly. Please Help
It could be a corroded or broken wire perhaps even lose wire Make sure bulb is all the way in and turned and inside connections or contacts are not corroded
