Difficulty maintaining depth

[Pascal]

The boat has a very clear tendency to sink slowly, without being able to maintain its depth - nor to go up - while there is little apparent damage, and no or few waterways ...
Is there a Mod to reconfigure this defect ?

Are your regulating tanks or buoyancy tanks damaged? I find that once those start taking damage depth keeping is very hard to keep (without messing with the speed or the dive planes).

I actually took damage to those in a recent patrol after hitting a convoy. After escaping, instead of going back for repairs i took on another convoy which proved the end of me. I could not properly keep depth without going to fast, hence my boat being loud, hence them always locating me. After another 20+ in game hours of depth charge, and further damage to that important equipment, i had to surrender on surface.

thank you for your answer - No, no major damage found, yet impossible to stop the submersible dive. Certainly, some tremors related to the depth charges
I use this Mod : NewUIs_TDC_7_5_0_ByTheDarkWraith
