They could claim its just a mode intended for tech diagnosis...to play devils advocate of course.Sucks for the owner shipping a dry rack is definitely an issue that should have been covered by warranty. And why have a dyno mode if it will cause denial of warranty claim. Either way will be interesting to see if there are more occurrences of this issue, my understanding is that it is a known issue with some BMW models.
You know, when a repair kit is already available for a system you put on a new car, maybe something else should be done.According to more than a few, this is a known BMW issue that affects several different BMW vehicles. As FasTTurbo indicated, this one was shipped dry, but there are BMW repair kits that, allegedly, address this issue. I hope 1A1 and SupraWillis see this thread. They know these cars as well, if not better, than anyone and I would like to hear their expert opinions on this.
