[20v] Intermittent no spark condition - 1989 Audi 90Q

I checked the distributor again, and sure enough the connector that goes 
through the body of the distributor to the hall sender was broken and 
loose.  Most likely one of the wires is making intermittent connection 
inside the plastic.  I ordered a rebuilt distributor since I couldn't 
find the hall sensor unit by itself anywhere (actually, I ordered *2* 
distributors, but that's another story).  So I got the new distributor 
in and the car is running well and I'm ready to set the timing.  I read 
in the service manual that in '89, the timing is done completely with 
the Audi tool that plugs into the service port on the transmission to 
get the readings and doesn't make any reference to using a timing 
light.  Can an '89 or newer car still be timed via a timing light on 
cylinder 1, (using the '88 and earlier procedure) or will that give 
erroneous readings?

Thanks in advance.
