'03 ML55 loud rattling ,clicking sound from engine
We have an '03 ML55, and when the engine is cold, there's a loud clicking and rattling sound from the engine. If I put it in first gear, rev to about 2500 RPM then ease off the throttle, as the revs are dropping through the 1400-1700 rev range, the engine produces the sound. It happens in normal driving too, but that's the easiest way to get it to make the noise. It does it until the engine temperature is about 70 Degrees C, as indicated on the gauge(or is that oil temp.?). thanks in advance for advice on what it could be.

The Starmark warranty on that car paid for itself on that service call.
