Airbus 320 - Engine Failure with Damage
The new ECAM asks you "if no fuel leak monitor imbalance". There is no requirement to do anything at this stage. you should be landing back in 20 mts. anyway. If there is delay and imbalance developes then fuel advisory will pop up. At that time you apply imbalance procedure if there is no fuel leak. The last line of the procedure states "there is no requirement to correct an imbalance until the ECAM fuel advisory is displayed".
