I have a used computer module, speedo cluster and warning light system (to the left of the speedo cluster). How do I get to these instruments to replace them? I also bought a front air dam spoiler (needs some repair) for this model off ebay along with the mounting hardware. I bought both euro and american mounting hardware because it was pretty cheap ($40) Any help on how this mounts or if I bought the right air dam? I agree with many of you who say this model is one the best things BMW ever engineered.
