Ifix; Can you tell me how long the PTU must run before the ECAM memo displays HYD PTU? - is it instantaneous, or after so many seconds? I fly the thing every week, but cannot remember what the PTU indications are on 2nd engine start!
(My thinking is that if the PTU is constantly cycling when it shouldn't be, we in the cockpit may never see it on the memo and would therefore not know if it was happening, unless we happened to see it during our system pages scan.)
Another thought is; could this be a sign that the hydraulic accumulator(s) need recharging?
I will endeavour to record details in the Tech Log as you suggest, should a fault ever arise.
