Diagnosing cold start injector in Coupe GT

[RJA]

Pulled the glovebox this morning to see if I could locate the hot start
pulse relay near the ECU, even though the Bently pictures do not show it
there.  Next to the two relays shown in the book is a third relay socket
(not shown in the book) with the right color wires for the hot start pulse
relay and.... no relay!  I suspect it fell out and is nowhere to be found,
but it certainly explains the problem.  Anyone have one of these kicking
around?  Audi part number is 813 906 064.
