	I guess apparently Audi engineers consider that the timing belt to be a
	service item and breakage shouldn't be a "problem" if it's replaced
	within its designed service life.  AOA probably stretched that a bit
	far with their maintenance intervals (to save cost).  I wouldn't be
	surprised if the Audi engine designers had shorter belt replacement
	intervals in mind.
	
	At any rate, I think it's probably safe to assume that timing chains
	will make its way into future Audi engine designs.
