WHINING NOISE
Whats up guys,
Bought a 2004 E500 4Matic a few months ago, has 99k on it. For some reason since i bought it, there is constant annoying whining noise coming from the engine. I replaced my power steering pump, filled it with the Mercedes hydraulic oil. Also replaced my idler pulley. Can't seem to figure out whats wrong with it. Drives fine and everything just very annoying. I've seen posts where members say that its the AC compressor, but the noise is still on even when i have the heat or air conditioning turned off.
