Unveiled in 2009, the BMW 5 Series Gran Turismo F07 was built not on standard 5 Series underpinnings, but on the extended wheelbase chassis of the F01 7 Series. Providing first-class rear legroom, an elevated driving position and an innovative two-piece bi-modal tailgate, it delivered bespoke luxury touring. Sustaining its supreme comfort relies on diligent BMW 5 Series maintenance, particularly regarding rear pneumatic suspension.
Under the sculpted bonnet, the six-cylinder N55 petrol (535i) and N57 diesel (530d, 535d) pair with the standard eight-speed ZF 8-speed automatic gearbox. Key mechanical watchpoints include electric water pump failures and oil filter housing gasket leaks. The standard self-levelling rear air suspension utilizes rubber air springs that degrade over time, causing the rear end to sag overnight.
