Which sonar do you use? The S-Gerat?
I think there is a problem with the Niebelung, but I'm not sure. It might also not fit with IX/D2.
If you stick with the IX/D2 it would be nice to inform us e.g. if one of the sonar types does not work (regardless of message or not).
All these problems with the IX/D2 and the XXI are due to the fact that these subs were the least tested; thus buggy...
