Problem with fog light

[Mario MKV]

Hello,
I'm having issues with driver side fog light on my Golf Mk5 GT tdi. Passenger side works perfectly fine but driver side won't. I tested with voltmeter and when bulb is out it shows 12v and when i place bulb shows 1.5v. Bulbs are new. Can you help me?
Thanks,

Just to clarify, front right fog light?

You spotted my trap... You need to check the Earth is clean and then check the power wire back to the Body Control Module but you may find the problem is internal within the BCM.

Thanks for reply,

The problem was on j519. After changing that module all fog lights are working now.
