📖BMW 6 Series Gran Coupé F06: an exquisite four-door luxury coupé demanding grand tourer mechanical care

BMW 6 Series Gran Coupé F06 (2012-2018)

Introduced in 2012, the BMW 6 Series Gran Coupé F06 transferred the low-slung elegance of the F13 coupe into a breathtaking four-door body with an extended wheelbase and genuine rear passenger luxury. Standing wider, lower and more dramatic than a BMW 5 Series, it delivers genuine grand tourer charisma. Enjoying this rolling sculpture requires rigorous BMW 6 Series maintenance matching its heavyweight executive pedigree.

The model lineup centres around the 640i (N55 turbo petrol), the immensely popular 640d (N57 twin-turbo diesel) and the potent 650i (N63 twin-turbo V8), all paired with the brilliant eight-speed ZF 8-speed automatic gearbox. Six-cylinder models offer bulletproof endurance, whereas the twin-turbo V8 demands close monitoring of hot-vee turbo cooling system lines, valve stem seals and engine oil consumption.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability
  • Breathtaking four-door coupe styling with an imposing road stance and luxurious leather-lined cabin.
  • 640i and 640d six-cylinder variants provide exceptional long-distance stamina, refinement and sensible running costs.
  • Superb eight-speed ZF automatic gearbox delivering seamless, rapid shifts and motorway cruising economy.

Chronic weak spots

Keep an eye on
  • N63 twin-turbo V8: inspect for heavy oil consumption, blue smoke after idle and brittle plastic turbo coolant lines.
  • N55 640i cooling and oil leaks: check electric water pump, thermostat and oil filter housing gasket.
  • Front suspension lower wishbones: heavy front kerb weight wears out hydro-bushes, causing braking flutter.
  • ZF 8-speed automatic gearbox: verify smooth gear shifting and plan fluid replacement around 80,000 to 100,000 km.
  • Frameless door glass and window seals: inspect automatic drop mechanism and check seals for motorway wind roar.

Critical deadlines

Do not miss
  • Brake fluid service: flush and replace every 24 months according to manufacturer intervals.
  • ZF 8-speed automatic gearbox fluid service: renew fluid and integrated pan filter between 80,000 and 100,000 km.
  • Engine oil and filter change: every 15,000 km or 12 months with BMW Longlife-04 approved synthetic oil.
  • Front control arm hydro-bushes and geometry: inspect every 40,000 km and replace bushes as matched pairs.
