A319 crew reported left wing leak ECAM during cruise portion of a ferry flight. Flight crew elected to divert and landed safely.

Narrative

Diverted enroute due to a L WING LEAK ECAM. We had ferried this aircraft the day prior; after the crew had reported the same ECAM. They MEL'd the L bleed and we flew the flight to ZZZ. Maintenance fixed the problem and we ferried the flight from ZZZ to ZZZ1 for reposition.About 1.5 hours into the flight; near ZZZ2; we got the same L WING LEAK ECAM. I gave Person A the radios and flight controls; and ran the ECAM. After I completed the ECAM; I went into the FM to see if anything else needed to be done. We read through that and then accessed the situation. We were now single bleed; single pack; the MEL from the day prior had a max altitude for this situation of 310. Although this MEL was not controlling; we felt it prudent to descend to at or below 310. Due to the L WING LEAK; being prohibited to fly in icing conditions; poor weather in ZZZ2; and with the lower altitude/lower landing fuel in ZZZ2 being significantly decreased; we decided to divert. We had fuel and time so we talked to dispatch and decided to divert to ZZZ3. We obtained NOTAMS; landing data; and went through the diversion guide. Once this was completed we had an uneventful approach and landing into ZZZ3.
