Update: The MB dealer replaced the harmonic balancer, did the steering pump upgrade (clamp & hose), fixed a split weatherstrip on the pass rear door, and replaced a sticky accelerator cable.

They declined to do the aux fan upgrade (unless evidence of blown fuses), informed me any cat converter problems were covered for 7/70, said oil consumption in excess of 1qt per 600mi would warrant a concern i.e. trigger the MB 10 year/150K mi warranty consideration, and stated the fuel filter upgrade is a 60K mi service visit item. I have 36K on my 2000 ML320.

I have till September 04 on the warranty yet so I expect I will return before then to ask again for the aux fan harness upgrade.
