X4 CBS Reset
- CBS covers same items as X3 — ISTA reset recommended
- Include drivetrain fluids in service schedule — CBS does NOT monitor transfer case or diff oil
CBS Covers Less Than You Think
BMW's CBS monitors engine oil, brake pads, brake fluid, coolant age, and spark plugs. It does NOT monitor: automatic transmission fluid, transfer case fluid, differential fluid, or air suspension fluid. Many X4 owners discover overdue drivetrain fluids only at 20,000+ km when symptoms appear. At 4M Car Care we maintain a separate service calendar for drivetrain fluids alongside CBS items — ask us for a full fluid audit at your next visit. A simple ISTA CBS reset at 4M costs .
