Actually didn't end up using BMW assist for recovery to my house - that took way too long. I used my auto aid membership, which took half the time.
Dick Lovatt have found the fault. Camchain has snapped and fallen into the gearbox.
I've not heared of a camchain snapping at such a low mileage - most definitely what is described as infant mortality amongst us reliability engineers, and is pretty darn rare.
What concerns me more is the severity of the failure mode ( locked back wheel). It is foreseeable that a camchain snap will lock the transmission, so there should be a "camchain catcher" in there to make sure that the severe failure mode is prevented.
I will be investigating this more.
They have ordered a new engine, and want to fix it, I have said that I'm not too happy about having a second hand brand new bike. Dick Lovatt have said that I need to talk to customer services, as they are only allowed to do what BMW head office say.
I tried to discuss with BMW customer services, but got the brush off - they said that my contract was with the dealer and not BMW, so I need to discuss this with Dick Lovatt....
So before I spend any more of my life in ping pong between the two, i am writing a letter direct to the managing director of BMW head office.
I'll let you know how I get along.
