My stock 240D idles quite smoothly, while my turbo 240 idles like a bulldozer rattling in the interior. When revved slightly it seems to smooth out. I have yet to install the engine shocks, which I am hoping will reduce the vibrations. Should I try any other fixes such as the rack damper pin, or is this normal for a 617 with a 240D flywheel?
