Launched in 2003 under Chris Bangle's daring design direction, the BMW 5 Series Saloon E60 introduced an aluminium front body structure bonded to a steel passenger cell for perfect 50:50 weight distribution. Packed with revolutionary technology, enjoying this futuristic executive saloon demands structured BMW 5 Series maintenance, addressing complex electronic modules alongside engine servicing.
Engine options range from the bulletproof M54 and magnesium-block N52 petrols to the mighty M57 straight-six diesel. Diesel variants require immediate removal or blanking of plastic intake manifold swirl flaps to prevent engine ingestion, while petrols rely on electric water pumps in the cooling system. The ZF 6HP automatic gearbox is durable but prone to mechatronic bridge seal leaks and electrical connector weeping.
