Solution

1. Oil Change

Sub-steps:
1. Gather necessary tools (oil filter wrench, socket set, oil catch pan).
2. Lift the vehicle and secure it with jack stands.
3. Remove the drain plug and let the old oil drain completely into the catch pan.
4. Replace the oil filter using the oil filter wrench.
5. Reinstall the drain plug with the specified torque (typically 25 Nm).
6. Fill the engine with fresh oil (use BMW-approved oil, typically 5W-30) to the recommended capacity.
7. Run the engine for a few minutes and check for leaks.

2. Replace Air Filters

Sub-steps:
1. Open the hood and locate the engine air filter housing.
2. Remove the clips or screws securing the housing and lift it off.
3. Replace the old air filter with the new one, ensuring a snug fit.
4. For the cabin air filter, locate its compartment (usually behind the glove box).
5. Remove the old filter and insert the new one according to airflow direction.

3. Brake Fluid Change

Sub-steps:
1. Locate the brake fluid reservoir and check fluid level.
2. Use a brake bleeder kit to draw out the old fluid from the reservoir.
3. Refill with new brake fluid (DOT 4) until the proper level is reached.
4. Bleed each brake caliper to remove any air from the lines.

4. Spark Plugs and Ignition Coils

Sub-steps:
1. Locate the ignition coil packs on top of the engine.
2. Disconnect the electrical connectors and remove the coil packs.
3. Use a spark plug socket to remove old spark plugs and replace them with new ones (check gap).
4. Reinstall the ignition coils and reconnect the electrical connectors.

5. Coolant System Maintenance

Sub-steps:
1. Inspect hoses for wear or leaks and replace as necessary.
2. If coolant is low or dirty, drain the system using the drain plug.
3. Flush the system with distilled water to remove debris.
4. Refill with BMW-approved coolant mixture (typically 50/50).

6. Tire Inspection and Rotation

Sub-steps:
1. Check tire tread depth using a tread depth gauge.
2. Inspect for uneven wear and any punctures.
3. Rotate tires according to the pattern recommended in the owner’s manual.
4. Inflate tires to the recommended pressure.
