Have the same issue. I tested several things and think it is produced by the drivetrain.
With my IG it only occurs inbetween 1850 and 2000 rpm and under load. If I go off the gas, it stops immediately.
Sadly the rpm range is reached If I drive something around 103 to 109 km/h in 8 gear, which is very very often in Germany...
