Hello,

I have a 2013 Polo and I am running into a problem where only the left headlight side doesn't work. None of the lights works except the day light.
I checked the bulbs and they are perfectly working (tried them in the right one), I also tried to change the fuse and still having the same problem. 
Can anyone help or suggest something?

Hi there,

Looks like you have a problem with your connection, it could be the cable or the connecter itself, or even the relay. 

For some reasons changing to a new bulb made my headlights works again.

Glad you could solve your problem.
