Maintenance with engine oil change (BMW 5 Series E39)

Maintenance with engine oil change is required for petrol-powered vehicles every 15,000 km or at least once a year (in spring if possible). For diesel vehicles, engine oil change is required every 10,000 km, and at least once a year under light vehicle load. Under severe operating conditions, such as city and short-distance driving, frequent mountain trips, trailer towing and dusty road conditions, service intervals should be reduced by half.

• Engine: change oil and filter.
• Diesel engine: Remove water from the fuel filter.
• Engine air filter: check the replaceable air filter element and replace if dirty.
• Perform an exhaust emission test (at idle, check the operation of the catalytic converter, interrogate the memory device of fault codes) — workshop work.
• Heating and air conditioning systems: check the condition of the microfilter, replace if dirty.
• Brake system: check the thickness of the front and rear brake pads. Check the parking brake mechanism (handbrake).
• Chassis and supporting body parts: check for damage and corrosion.
• Monitor the operation of all electricity consumers.
• Cooling and heating system: check the fluid level, top up if necessary. Check the concentration of antifreeze.
