My 1994 E420 with M119 engine had a full maintenance history from new with no record of water pump replacement, although did have regular coolant changes at dealer. 1st owner drove over 100,000 miles in33 months, sold to 2nd owner who took 17 years to add another 100,000 then came me. Never had any indication of pump failure, fan clutch done several times over life of car. Don't remember mileage when sold, but was around 300,000. Best engine of any car I ever owned. When sold, still did not drip or burn oil and was eerily quiet at idle.
