Narrative:

I was the captain on [flight to] ZZZ. This aircraft had a requirement for maintenance to confirm there was not a 'left/G system disagree' caution message present; prior to each departure. Just before takeoff from [departure airport]; a bscu system 2 fault ECAM annunciated. We delayed take off to resolve this issue. First officer was the pilot flying. On final approach to runway xxc; pilot flying called for 'gear down'. I moved the landing gear handle to the down position…three red gear unlocked lights indicated on the forward panel...gear indicated up on the wheels ECAM page with an amber left/G control message. There were no other ECAM's or warnings. Cycled the gear handle up; then back down; same indications. All hydraulic systems indicated normal. [We advised ATC and that] we wanted to be vectored out to downwind again to work a 'landing gear issue'. Designated the first officer as pilot flying and ATC communicator while I advised the flight attendants and passengers. Fuel on board was approximately 6;000 lbs at this point. I referenced the left/G gear not down QRH. Completion of this checklist sent us to the left/G gravity extension QRH. At some point here; gave the flight attendants the briefing. Discussion with first officer resulted in consulting [maintenance control] (through dispatch) to see if there were any other options prior to manual gear extension. [Maintenance control] did not have any other actions to recommendwe reviewed the gravity extension checklist which stated nose wheel steering would not be available on landing. ATC; arff; and the [company] station were all advised of this. Approximately 25 miles from the airfield; we were cleared for the visual approach to runway xxr. The landing gear was manually extended per the QRH. Flap extension and remainder of the approach and landing were normal; with the exception of nose wheel steering. The aircraft was brought to a stop on the runway centerline...brakes set...APU started; and then engines shut down. ZZZ arff examined the aircraft and advised there were no obvious issues. We were eventually towed to the gate with an arff escort. Fuel on board at the gate was 3;500 lbs.
