I was thinking also about the fuel thing, but 7 tons of difference due to inaccuracies in the fuel calculations seems excessive on an A320. On the flight we used around 11,5t of fuel, so 7 tons is around 60% of the fuel used on that flight. Today, on the same aircraft we observed a similar behavior but as the difference stayed slightly below the threshold of 7 tons we didn't get the "Check GW" message today. During todays flight we could not engage AP2 during the whole flight (surprisingly, it could be engaged again after landing) and got a "F/CTL Sidestick priority" ECAM after parking, but I am not sure if this is in any way related to the discrepancy in GW at all or not.
Definitely sounds like an aircraft I would like to avoid.......
