If you now order to surface the quick-diving tank is emptied and the Uboat surfaces. Is this correct behaviour??
Question: How were the diving-tanks emptied?
- By pump (->battery supply) or
- by pressure air (->compressed air supply)
- or both of them

I tested this. I emptied the batteries (needle on zero, no speed at all at ahead flank) and the tank by continuosly pressing key "E" and reordering the depth before surfacing.
At these conditions, at all engines stopped, I was still able to surface in 15' from 100meters pressing "E" key, or "S"! Also I was still able to change the depth acting on the needle of the depthmeter.
However even if the crew said to me we were out of compressed air, and I pressed E for long time to exhaust all air, I noticed the pressure air-meter needle never went on zero, but it stopped at 1 notch over zero.
I guessed I got the same behaviour of the batteries and amperometer before your fix!
I hope this help!
