Ok so I have a 2008 520D with @ 450,000 km on the clock.....I have had an issue with a halo light not working on the drivers side, I tried a new blub but still no joy.. She passed her yearly test with the blown bulb, so I left it..... Now the other day coming home I got a cornering light Malfunction and my head lights only work intermittently...,and will turn off even after been turned on...I still have the light on the dashboard so I dont think its the stalk...

Could it be a wiring issue (it affects both headlights) or could it be a light modular that is\has failed.

any idea guys.....

Regards

 

Check the wiring first. That's most likely the culprit.
