- My cousin who owns a BMW Indy shop in Los Angeles area told me after I bought the 1998 528i and 2006 X5: close the sunroof and never use it again LOL.

He got tired of fixing sunroof, which is not any mechanic favorite topic, simply b/c it is annoying with small little parts and problems can recur if they don't take care of all small items when having the sunroof apart!

So yes, you are lucky your sunroof failed in a closed position.

Roll down your window and enjoy the fume from diesel trucks...
