Depth:
Expert/Dealer-Level. Covers all aspects from basic maintenance to complex diagnostics and complete overhauls, mirroring the information used by BMW factory-trained technicians.
Oil Change:
Typically every 10,000 - 15,000 miles or 12-24 months, as indicated by the vehicle's Condition Based Service (CBS) system. Manual will detail how to reset CBS.
Spark Plugs:
Intervals vary by engine, but commonly around 60,000 - 100,000 miles.
Brake Fluid:
Recommended every 2 years, regardless of mileage.
Engine Oil:
Requires specific synthetic engine oil meeting BMW Longlife specifications (e.g., BMW LL-01 or LL-04, depending on region and engine). Viscosity typically 0W-30 or 5W-30.
Coolant:
BMW Blue Antifreeze/Coolant (G48 ethylene glycol based) or equivalent, mixed 50/50 with distilled water.
Power Steering Fluid:
Typically Pentosin CHF 11S or equivalent hydraulic fluid for hydraulic power steering systems. Specific models may differ.
Common Problems:
Coolant leaks (water pump, hoses, valley pan), oil leaks (valve cover gaskets, oil pan gasket), VANOS system issues, ABS/DSC sensor failures, iDrive system glitches, suspension component wear (control arms, bushings), electronic module failures (e.g., LCM, DME), fuel pump issues.
Troubleshooting Guides:
The manual will provide detailed diagnostic procedures for these and other common issues.
