"rattling" sound on acceleration- 2003 E500
My 2003 E500 has a subtle noise on acceleration that I would describe as a subtle "diesel-like" clatter, or "tapping noise". It's most pronounced on mild acceleration, and goes away on full throttle. I just bought this car this week and was wondering if this was a normal sound for this V8; although I've had other M-Bs with V8s, none of them have made this sound (32v 91 SL500 & 97 E420) Even after running 93 octane, the tapping noise has not diminished. Is this the sound of a normal 24-valve V8? The car runs very smoothly, with no vibration or hesitation, and feels very powerful too. Crude stopwatched 0-60 times are in the 5.7 second range, so performance is excellent. Any thoughts?
