📖BMW 4 Series Coupé G22: a striking modern sports coupé where onboard technology equals mechanical stamina

BMW 4 Series Coupé G22 (2020-Présent)

Arriving in 2020 with its distinctive vertical kidney grille, the BMW 4 Series Coupé G22 backed up its bold exterior with exceptional structural rigidity, wider tracks and bespoke chassis tuning on the CLAR platform. A fast, refined modern coupe, enjoying its full dynamic envelope requires structured BMW 4 Series maintenance that balances mechanical servicing with comprehensive digital vehicle checks.

The powertrain lineup is dominated by modular B48 four-cylinder (420i, 430i) and sensational B58 straight-six (M440i) engines, paired seamlessly with the ZF 8-speed automatic gearbox. This mechanical package is remarkably robust, but the cooling system requires inspection around plastic cylinder head hose flanges and coolant expansion tank caps.

Modern onboard systems - including digital instrument displays, driver assistance radars, cameras and the 12V AGM auxiliary battery - must be thoroughly verified on a proper road test. Ensure gear shifts remain imperceptible and check wide performance tyres for even wear across their tread width.

Owner notes

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

Reassuring points

Reliability
  • Modular B48 and B58 turbocharged engines offering outstanding stamina, refined power and tuning potential.
  • Stiff CLAR chassis architecture providing clinical cornering precision and superb motorway refinement.
  • Intuitive iDrive infotainment system combined with high-grade interior fit and finish.

Chronic weak spots

Keep an eye on
  • 12V auxiliary battery and electronic driver assistance: weak batteries cause spurious warning chimes.
  • Plastic cooling hose flanges: check cylinder head coolant vent pipe for brittleness and white fluid crusting.
  • ZF 8-speed automatic gearbox: verify silky shift quality and confirm fluid servicing on higher-mileage cars.
  • Brakes and performance tyres: M Sport compound brake pads and staggered tyres wear rapidly under hard driving.
  • Particulate filter (GPF) on petrol models: short urban journeys can lead to soot accumulation and warning lights.

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: replace fluid and integrated filter pan between 80,000 and 100,000 km.
  • Engine oil and filter change: every 15,000 km or 12 months using BMW LL-04 or LL-17 FE+ synthetic oil.
  • Spark plug renewal: replace every 50,000 km on B48 four-cylinder and B58 six-cylinder engines.
