Timing chain tensioner defective

CONGRAGULATIONS!!  Great to see BMW backing their product.  When I read your post my stomach turned.  Imagine loosing an engine that close to the warrant expiring. Are they covering labor?

Sorry for the late reply. The good news is Yes.  There was no charge to me at all.
Couple of other things.
Unlike years past, they didn't reset the "clock" to zero - apparently that's not allowed in Australia today.
They did not note this work in the service manual. Not sure if this is better for me or not, but I have the service receipt to prove it took place.
BMW have applied limiters until 1,000kms then I MUST return the bike for a service / oil change etc which I'll be sure to do.
So a good ending and again, thanks to all for your advice and checking in on my progress.
