I agree with you in principle that BMW has no obligation to fix this under warranty, OP voluntarily altered his contract with them...I'm just saying, you may as well see if they can help out in any way. Worst case they say take a hike, and you're back at square one. If OP is willing to pay, there is no doubt BMW can fix it, an adaptive failure isn't particularly exotic. Just expensive
