Thanks to all in advance for this site and it's cornucopia of knowledge overload. I have recently begun my foray into INPA, DIS, etc. and all that it entails. Been working on BMW's for thirty plus years, although not exclusively. I have been at Amazing Automotive/Tune Ups n Such for over twenty three years. I love all machines but have a special place in my heart for older European asphalt grinders. I look forward to increasing my participation in the BMW community as they seem to be so very popular of late.
