2019 Levorg
I have a 2019 2.0 l Levorg and recently it developed a noticeable power flat spot from around 1200 to 1600 RPM under low speed and load.

The car has been hooked up to the diagnostics and is showing no fault. Lines are cleared, fuel filter is clean and there is nothing obvious that is at fault

My mechanic is suggesting that there is a Map file issue and to take to Subaru (which I have booked in)

Any suggestions before I go down the rabbit hole of Subaru service?
