This is Koji
Kato of 11G.
In regard to NV [Noise and Vibration], at the moment there is no function change for
the function of concern. In the future, I will ask about the 250L status and check it carefully.

Actually, abnormal phenomena
also seem to be happening in the 250L during sudden steering (EPS) and when the ABS
operates. Additionally, the large variations of electrical load in the new
250L V8s seem to be causing problems of large idling vibrations.

phenomena are present. Recently, such unexpected phenomena have also appeared
in the 120L, 130L and 045L, which have only a small amount of equipment,
which worries me.
