2. Inspect and Replace Engine Oil

• Sub-steps:
  1. Check the engine oil level using the dipstick.
  2. If oil is low, add the appropriate type (BMW Longlife-01 or Longlife-04).
  3. If the oil is dirty or has not been changed per the maintenance schedule, perform an oil change:
     • Drain old oil and replace with new oil.
     • Replace the oil filter.

  4. Remove the old solenoid and install the new one.
  5. Reconnect the electrical connector and secure the solenoid with bolts.
• Tools Required: Socket set, torque wrench.
• Torque Values: Typically around 10-15 Nm, check specific service manual for exact values.

4. Inspect Timing Chain/Belt

• Sub-steps:
  1. Remove any components obstructing access to the timing chain/belt cover.
  2. Inspect chain/belt for wear, tension, and alignment.
  3. If wear is evident, replace the timing chain/belt and tensioners.
• Tools Required: Torque wrench, socket set, timing tool kit.
