I'm eyeballing a 2006 325xi that the owner says has a faulty DSC module. Says it causes all manner of warning lights and it affects how the AWD system works in some way. If the DSC module has failed, what does it do to the drivetrain? I'm considering getting it simply because it's very cheap, titled, and I "think" I can source the module inexpensively. Don't know if it's worth investing in to flip the car, though...it's far from the car I want but it's a car I could be pretty content with while I wait.
