The resistor is important to network communications and could create faults.
Part of completing the SIB the technician will check and clear any faults. If there are new software updates for any of the modules then those might be completed at the same time.
Maybe removing the faults or updated software that is changing the feel and sound of the M4...
OR maybe it's just that new car feel of having the service wash before delivery.
