You dove U 1277, U 352 and U 1105... and it's not yet in Wannadive :) You should add them.
If you wanna dive the U 171, the best is to call a local dive center. Try searching Google with "Groix club plongée" in French.
I found SUBAGREC, but there are certainly other dive centers that offers this wreck dive.
