Okay, I now have acquired further wisdom on the issue. Pulled and 
disconnected an injector tonight, and it was indeed of the fine thread 
type, as probably expected. To my surprise, I was also able to clean the 
body just enough to be able to recognize the part numbers on it, which 
were VAG 035 133 551 C and Bosch 0 437 502 032.

As it happens, a fellow Audi owner had a disconnected 551 F I could 
compare my 551 C with, and they were of equal shape and length downwards 
from the O-ring level. Apparently the 551 C is an older, dropped 
revision of the fine thread injector, and I assume I'll be correct in 
using the Bosch number for 551 F in any further inquiries.
