Not sure if this will help, but I just looked at the injectors that I 
pulled from my '85 last year.  There are two p/n's on the "body" of the 
injector.  One looks to be the Bosch number, 437 502 023.  Directly 
under it is the Audi p/n 049 133 551A.  There is nothing on the hex 
part of any of the injectors.  These were the injectors that were in 
the car when I bought it 11 years ago, so they are probably the 
originals.

The invoice I have from Blau for the replacement injectors I bought 
list p/n 437 502 023.  Can't tell you what is on the injectors 
themselves since they are in the car now.
