The CBS engine-oil interval is at most 10,000 miles or 12 months, whichever comes first; the display may call for it sooner depending on driving conditions (short trips, cold starts, idling, high engine speeds). | 10,000 mi / 12 mo≈ 16,000 km / 12 mo | $120-$180 | |
| Cabin Air FilterReplace the ventilation microfilter at every 2nd engine oil service (approx. 20,000 mi). Not shown in the CBS display; done together with the oil service. | 20,000 mi≈ 32,000 km | $50-$90 | |
| Spark PlugsReplace at every 6th engine oil service (approx. 60,000 mi). Not shown in the CBS display; done together with the oil service. | 60,000 mi≈ 97,000 km | $250-$400 | |
| Brake FluidSafety itemTime-based only (no mileage): replace when the CBS display shows brake fluid due. BMW's CBS brake-fluid interval is 24 months after each change; the first change may be scheduled later, counted from the production date. | 24 mo | $120-$180 | |
| Brake InspectionInspect only. Front and rear brake pads are monitored by CBS (remaining miles shown); replace pads when displayed and check disc surface and thickness at that service. Brake lines and connections are checked at each CBS vehicle check. | As needed | — | |
| Engine CoolantNo scheduled replacement: the engine cooling system is factory-filled with long-term rated fluid; replacement is only necessary when repairs are performed; coolant level and concentration are checked at each CBS vehicle check. | As needed | $180-$280 | |
| Automatic Transmission FluidNo scheduled replacement: the 8-speed automatic transmission is factory-filled with long-term rated fluid; replacement is only necessary when repairs are performed. | As needed | $350-$500 | |
| Transfer Case Fluid (xDrive only)No scheduled replacement: the xDrive transfer case is factory-filled with long-term rated fluid; replacement is only necessary when repairs are performed, unless the vehicle's service system calls for it. | As needed | $180-$280 | |

GarageHub · Free · Your AI MechanicOpenThe 2024 BMW 4 Series (G22/G23/G26) is sold as a Coupe, Convertible and Gran Coupe with a turbocharged four-cylinder in the 430i and a mild-hybrid turbocharged inline-six in the M440i, each with rear-wheel drive or xDrive, all sharing BMW's Condition Based Service (CBS) system, in which the car's service display shows when each item is due. This schedule covers the CBS services and the items done alongside the oil service on the 430i and M440i; the M4 has its own schedule.
What happens if you skip it
- Neglecting oil changes on turbocharged engines accelerates turbo bearing wear, leading to $3,000–$5,000 turbocharger replacement on 430i/M440i models.
- Deferred brake fluid flushes absorb moisture, lowering boiling points and causing spongy pedal feel or complete brake fade during spirited driving.
- Ignoring transmission fluid changes in the ZF 8HP automatic can cause harsh shifting, valve-body clogging, and eventual mechatronic unit failure requiring $4,000–$6,000 transmission replacement.
- Failing to replace 12V AGM batteries on schedule strains the alternator and can trigger limp mode or no-start conditions, with unregistered batteries causing premature failure of the new unit.
- Postponing spark plug replacement on turbocharged engines causes misfires, triggers check-engine lights, and can damage catalytic converters ($2,000+ per cat).
Common issues at higher mileage
- 40,000+ mi
- Carbon buildup on intake valves (all direct-injection engines) causes rough idle and power loss; walnut-blasting service costs $400–$700.
- 50,000+ mi
- Water pump failures on turbocharged I4 and I6 engines can cause overheating; electric pumps are common failure points requiring $600–$1,200 replacement.
- 60,000+ mi
- Turbocharger wastegate rattle on B58 3.0L I6 (M440i) may develop due to actuator wear, sometimes covered under extended warranty if documented early.
- 80,000+ mi
- High-pressure fuel pump failures on direct-injection engines cause rough running and limp mode; replacement runs $1,200–$2,000 including labor.
- 100,000+ mi
- xDrive transfer case actuator motors may fail, causing AWD system faults and defaulting to RWD-only mode; repair costs $1,500–$2,500.
