My car has been updated by the local dealer here at BA, Argentina to the i level F20 18-07-531 from 15-11-505.
After this upgrade the engine is hesitating at low rpm ( between 1000 and 1500 rpm ) as well as not having the same response it used to have with the previous i level. Looks like the performance has been reduced, like if the car were running very lean, with not enough fuel. There are no codes showed at ista D, no misfires, no nothing indicating a fault.
Is anybody aware of issues at DME with this i level?
Car is BMW F30 330 LCI Sport Line 8AT, year model 2016.

Thanks for your help

PS: am planning to come back to the dealer, but before listening " everything is normal" I wanted to have your opinion / feedback.
