Long story short: my BMW motor exploded, and NA says it's my fault with no proof. So, I've decided to go legal. I used that legalmatch site, but any recommendations would help out tremendously. Thanks!

 

Did they ship off the DME to BMWNA and have it read? The contents of the DME should tell the story - one way or the other.

If you have a good relationship with your dealer they should go to bat for you at some level. What car/year? What happened?
