Hello, I'm having trouble diagnosing an issue with my new Saab. I recently purchased this 2006 9-3 saab. Its been great with the exception of a few nagging issues. The first was the headlight, the passenger side low HID was not working. After some troubleshooting and switching of bulbs, ballast etc. I found it likely to be an issue with the control unit. I switched that out today with a known good unit, the light worked! Problem is it won't go out. Key off engine off and the right side low beam stays on. No other lights just that one. Any ideas?

 

I can see this was years ago but did you ever find a solution to your problem? I'm having the same issue.
