Possible helpful website
 

My dad came across this site online and purchased a rebuilt display screen basically the obc on our car but bigger for his saab. He mentioned that theyhave some bmw parts and it's kind of local for me since it's in mass. Anyway this is the website www.bba-reman.com not sure on prices seems like you need to call for that info. I came across this section of the site and lists some problems with the bmw's by chasis and year,thought it was interesting. http://www.bba-reman.com/content.asp...s_and_problems
