I don't see what he proved in that post that would lead you to conclude that it was "sad" that BMW didn't cover him. I know he *said* he had bent valves, but unless I'm missing a post, I didn't see anything proving that.
He also never indicated who tuned his car, or what specific information the regional rep gave him. He easily could have had a shitty tune which blew out his ringlands...he could have money-shifted the engine. There are a number of things that could have gone wrong here.
But, like I said, you are really taking full responsibility for your car if you start messing with the programing. But if you buy the programing from a reputable tuner, I think your chances of encountering issues are very low.
