I have a 2005 C240 4matic sedan with 76k miles
I am getting a loud engine whining noise at start up that slightly dies down when engine is warm. But when in "park" and any amount of gas pressure is applied engine whine gets louder, even when in drive there is loud whine all through the gears... Just replaced the power steering pump two days ago and noise didnt go away... any one else experience this annoyance or have any suggestions to try? any ideas Please!!
