Reliability snapshot
The E39 5 Series is widely regarded as a high point for the model. It is mechanically robust; common age-related items are the plastic cooling system (radiator, expansion tank, water pump), front suspension thrust-arm bushings, VANOS on six-cylinders, pixel failure in the instrument/on-board displays, and — on V8 M62 cars — timing-chain guides and cooling. Kept on top of cooling and suspension wear, the E39 remains a durable and satisfying car.
