The 1991–1996 BMW 525tds Sedan (E34 generation) is a European diesel variant of BMW's popular midsize luxury car. Enthusiasts have mixed feelings; some appreciate its economy and durability, while others consider the later E39 525tds to be problematic or recommend petrol alternatives. It is known for its reliable turbodiesel engine and classic E34 driving dynamics. Today, this model is suited for enthusiasts seeking a classic BMW diesel with good fuel efficiency for daily driving or as a project car, provided maintenance is kept up, particularly regarding rust and aging components.
The 1991-1996 BMW 525tds can face issues like a failing diesel pump if the fuel tank is less than half full, and broken fuel tank supports. Maintenance is noted as not being cheap, but the E34 platform is generally reliable and has a strong following for self-repair.
