Thanks, Tom.

Hooked up the VC to the ECU and cleared the error codes to be sure all was
well with the set up, then moved the VC to the AB terminals. The VC
recognized that it was seeing a controller but could not download anything.
Noticed that the white connector had only one wire to it, should be two,
send and receive? Will dig into this. Will swap this car back to the owner
and retrieve mine and check it for one or two wires in this white connector.
Last resort will be to pull the AB error bulb.

More later, Bernie

OK Guys, I found my never used Ross Tech OBD2 to 2x2 interface cable for
these old cars and son Dean is bringing down his Vag-Com this afternoon.
I¹ll tear into the center console to find the AB 2x2 receptacle. Anyone have
VC AB reset instructions? Hooked up now what?

Thanks, Bernie 
If memory serves correct, just take the panel off on the driver side -- I
think there is one screw to remove the topmost carpeted segment.  Then,
you'll need to fish around to find the leads.  Probably under the Air Bag

The precise location of the carpeted segment can be seen in the interior
picture of my 91 200q on the market:
Audifans Marketplace | 1991 200q20v

Look through the bottom portion of the steering wheel.  The brown portion
where your right knee would be is that portion of the carpet I removed to
reset the AB light.

Hook them up the same way you would the engine I/O ports, turn the engine on
and, I believe, go to the airbag tab on Vag Com, read the fault codes, then
clear them.

Let me know if you need more precise directions, and I will do a run through
on my car and report back to you.
