Passenger Dipped Beam

[s8utt]

So during this little flooding spell we had I hit some water on a road, it wasn't too bad, like probably 6-8 inches deep and I carried on.

Arrived at my destination and left the car for a few hours, on my return my passenger side headlight was out. Looking at the actual headlight it had obvious signs of water droplets on the inside.

So I dried out the headlight and changed the bulb ( H9).

It seems the bulb is not the culprit, Vagcom shows nothing obvious, and all the other lights in the cluster are working.

I put a multimeter on the bulb plug and it reads 12v but the light doesn't work.

So what am I missing ? Some new technology wizardry or just stupid owner error.

Any suggestions ?
Thanks
