Hi fellow briskoda members I am having an issue with some aftermarket headlights i have. 

They are retrofit lab projectors fitted inside the halogen housing, they have been fitted over a year and been working fine till recently passenger bulb failed.

I put in new bulbs but the bulb flickers asif it's trying to power on, ballasts have been swapped around and have been ruled out. 

Just wondering if anyone could point me in direction as to what else to check next, have checked fuse number 54 and swapped for another one but still no luck.

 

The new bulb may be faulty, try another one.

I have tried both bulbs as bought as a pair direct from retrofit lab and not working.

Check the wiring between the ballast and the bulb. Maybe use some cleaner and dielectric grease on reassembly. Does the flickering bulb work fine in the other headlight?

 Wiring is fine on ballast i think mate however have noticed the wire seems frayed/damaged where the hid wires ( white and blue) connect to headlight wiring. I have not swapped the bulb onto driver side yet as I managed to thread one of the screws for the backing cover. Going to remove it with pliers or drill out and try the new bulb on that side.

Also not sure if relevant or not have a fault code for 00991 interior lights short to plus, however all my interior lights seem to be working fine.
