Engine oil

BMW’s published oil-change quantity is 6.5 l. This is a service quantity, not an amount to pour in as a top-up: check the level after filling. For petrol top-ups the F31 handbook lists BMW Longlife-01, Longlife-01 FE or Longlife-04 and SAE 0W-40, 0W-30, 5W-40 or 5W-30. Match the approval to the engine and market; viscosity alone is insufficient. No additives.

Maintenance and CBS deadlines

CBS calculates deadlines from use; read distance and date under Vehicle information → Vehicle status → Service requirements. Oil, front and rear pads, brake fluid and vehicle check are separate items. This handbook does not set a universal oil mileage or a numeric brake-fluid interval here. The F31 handbook’s service table specifies oil, oil filter and air-conditioning microfilter at every oil service; spark plugs and air filter at every second oil service. Change the air filter sooner in dusty conditions.

Timing drive

Chain-driven timing. The consulted BMW maintenance table contains no periodic chain replacement: do not assign this engine a belt interval. Noise or a timing fault calls for diagnosis, not simply a CBS reset.

Documented faults and recalls

ADAC’s 3 Series list includes starter-relay corrosion with a fire risk (August 2026) and the driver-airbag inflator (September 2024). These campaigns span multiple models and periods: only a VIN check and completed-work history establish applicability.

Prepare the service

Bring the VIN, build month, N55B30A code and 225 kW rating. Record CBS dates and counters, previous oil services and filter changes; bring the key used for the last journey. Have the oil and work itemised on the invoice and the service recorded. Report storage with the battery disconnected so time-based deadlines can be corrected.
