	Does the Ur-Q have something similar to my '85 5KT for diagnostics?
	A handful of problems (mostly ignition/sensor related) can be
	located on mine using the tach and the check-engine light. Some
	of the faults can be located even if the engine won't start
	at all (you're normally required to drive the car at 1.2+ bar
	and 3000+ rpm to store the codes).

	I know there's no Bentley for these beasts, so if there might
	be such a feature, I'd be happy to fax the appropriate pages
	from mine.
