Hi,
Can you describe More in detail how this happened, did you install something, coded something, installed aftermarket xenons maybe?
Can you Post auto scan for The car?
Had Similar issue, but only that The OSF bulb Was allways on, dont remember The codes which i did have.
I had faulty BCM, The ic chip on bcm which controls The bulb Was burned.
I had 1K0937086G unit, If you have burned bcm, source new with exact same number to avoid hassle. (Needs to Be coded) byte18 for o2fl
Maybe you can test to trip wire off from connector at bcm, connector T52A PIN 9, to measure connection beetween bcm to bulb If its okay or short.
Here to another Forum, where is pinout for BCM
