i don't think its needed. as we are now it may work, but anything even remotely like this will become a i'm better than you thing as we grow. its also not fair to the people who don't have Bimmers and can't make DIY's (ostracizing enthusiasts because they don't have the means to make a DIY is wrong) or don't have the mechanical inclination to make a DIY (not everyone is capable of DIY-ing)
not needed.
personally i see a lot of nonsupport and then the mods are trying to work their way around to get support..... it sounds like the community has spoken.
