📖BMW 6 Series Gran Turismo G32: an ultra-refined luxury crossover where air suspension and transmission care rule

BMW 6 Series Gran Turismo G32 (2017-2023)

Launched in late 2017 to succeed the 5 GT, the BMW 6 Series Gran Turismo G32 adopted a significantly sleeker, lighter and more elegant silhouette on the rigid CLAR architecture. Bridging the gap between an executive estate and a luxury limousine, it offers an elevated seating position, a massive 610-litre liftback boot and standard automatic rear pneumatic suspension. Maintaining its silken touring manners requires structured BMW 6 Series maintenance across running gear and electronics.

Under the bonnet, modular B48 four-cylinder petrol and refined B57 straight-six diesels (630d, 640d) pair with the buttery eight-speed ZF 8-speed automatic gearbox. The standard self-levelling rear air suspension delivers cloud-like comfort, but rubber air springs must be checked for slow leaks that overwork the onboard compressor.

The powered liftback tailgate, deployable active rear spoiler and 12V AGM auxiliary battery require routine inspection. Sourced with verified service records, a G32 Gran Turismo provides peerless long-distance travel comfort and versatility.

Owner notes

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

Reassuring points

Reliability
  • Much sleeker and better-proportioned design than the F07, featuring a huge 610-litre electric hatchback cargo bay.
  • Lightweight CLAR chassis platform combined with standard rear air suspension delivering supreme ride comfort.
  • Exceptional long-distance endurance, refined torque and economy from the B57 3.0-litre straight-six diesel.

Chronic weak spots

Keep an eye on
  • Rear air suspension bellows: inspect rubber airbags for cracks, slow overnight leaks and compressor running time.
  • 12V auxiliary battery and onboard electronics: weak batteries cause spurious camera and driver assist faults.
  • ZF 8-speed automatic gearbox: verify silky gear changes and plan fluid renewal on higher-mileage examples.
  • Active rear spoiler mechanism: inspect motorized spoiler drive gears for dirt accumulation and smooth deployment.
  • B48/B57 cooling connections: inspect plastic coolant hose flanges and expansion tank caps for white residue.

Critical deadlines

Do not miss
  • Brake fluid service: flush and replace every 24 months according to manufacturer schedule.
  • ZF 8-speed automatic gearbox fluid service: change fluid and integrated pan filter between 80,000 and 100,000 km.
  • Rear air suspension bellows inspection: check airbags for perished rubber every 60,000 km or 5 years.
  • Engine oil and filter change: every 15,000 km or 12 months with BMW Longlife-04 approved synthetic oil.
