Even if there was no relationship at all, Dinan "takes over" the car's 4-year warranty following installation of their software and/or parts, so you're covered in any case.
I've been a customer of both BMW and Dinan since 2002 and it's been all good, right up to and including present day.
+1. I've worked with several dealerships to get the Dinan software installed. As a matter of fact, I have an appointment tomorrow morning at BMW to get upgraded to the Stage 2 software.
If you do go through a dealer, just make sure he knows his Dinan stuff. Don't be fooled by a salesman...
