So I believe I found a replacement for my half broken mirror. Knowing that my car has auto dim on the inside and outside mirrors, LED for the alarm and the garage door opener I think my part number is this 51167028444 found here http://realoem.com/bmw/showparts.do?...29&hg=51&fg=40 . As you can see it was discontinued and says "See EBA 0139396, BED 0415578, RA 5116060". Does anybody know what that means? Also If the mirror itself auto dims would it be able to control the side mirrors to auto dim if put on a car that has it? Any help would be great appreciated! Thanks.
