Idle Log 2019 X3M40i

This is a 2019 X3 M40i with 36400 miles. Plugs and Coil has been replaced 500 miles ago. NGK94201 Spark Plugs with stock gap. OEM coil pack. It has long been a issue with idle vibration before I changed my plugs and coil. Engine mount has been replaced by dealer under warranty, but new engine mount doesn't help the rough idle.
