I'm sure if you plead your case, ie your problem arose whilst the bike was under warranty, then BMW will probably look at it sympathetically. It depends on how you approach them I feel. How it came to be known was the BMW in Germany looked at the readout of my bike here in UK as my dealer was unable to see any problems showing up but the bike itself was not starting. I think different dealers in UK seem to have different attitudes.
PCV. I'm only giving my experience. Only you can decide on if you think it's useful or want to act on it.
I have discovered on this forum that some do tend to "poo poo" other people's help/ideas however well meaning.
