Good morning ,

I have an E60 with factory fit HUD , a short while ago I hit a pothole with my left front wheel on a really cold and wet night. Since then I have noticed a line in the display of my heads up , not horrendous but can be seen. If I look down into the HUD I can see what appears to be a small crack on the mirror or glass inside. Has anybody had any experience of this ?
How is the best way to access internals on it ?
If too much of a PITA I will likely leave alone !

thanks in advance.
