Hi folks, my name is Colin and I just joined the site. I just bought a 1991 318iS that needs a little love, so I've been searching and reading this site and it's proven to be a great resource.
I also own a 1986 325 and a 1989 M3, but I recently saw a 318iS for $800 so i decided to see what the poor man's M3 is all about.
The car I bought doesn't have an Active Check Control unit near the rear view mirror. It just has a blanking plate there. Is this typical? I assume I can just add a unit there? The car has the rare glass moonroof option

, so I'm wondering whether this is the reason why the unit is deleted?
Thanks guys.
Cheers,
Colin
