Om 656 low idle
Please help in this i have cls 400d engine om 656 2.9 or 3.0 2xturbo it runs smooth no issues on that.
However in the day when cabin is hot and ac is on it idles at 700 or 750 which is perfect as you don't feel any vibrations in the cabin. However if you swift off the ac or in the night it idles at 500 or 550 rpm here you feel like a war zone everything is vibrating from brake padles to whole cabin.
Can anyone point to the right direction as if we can increase the idle speed or what needs to be done for it.
