"Repair Instructions"
The E89 Complete Vehicle document mentioned above refers to something called "repair instructions" a few times.
Anyone have any idea where to find the repair instructions that they are referring to? I did try and search but it came back with so many threads I never would have been able to look at all of them. Thanks for your help, Marv |
