why does my BMW 5 Series F10/F11 (2010-2017) have low oil pressure

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and the engine is cool.
• Disconnect the battery to prevent any electrical issues.

2. Change Oil and Filter

• Tools Required: Socket set, oil filter wrench, oil catch pan.

1. Place the oil catch pan under the oil pan.
2. Remove the oil drain plug using a socket and allow the old oil to completely drain.
3. Replace the oil drain plug and tighten to the manufacturer's torque specification.
4. Use the oil filter wrench to remove the old oil filter.
5. Apply a thin layer of oil on the rubber gasket of the new oil filter, then install it hand-tight.
6. Fill the engine with the appropriate type and amount of oil as specified in the owner's manual.

3. Inspect and Replace Oil Pump (if necessary)

• Tools Required: Socket set, torque wrench, engine hoist (if applicable).

1. Remove any components obstructing access to the oil pump (e.g., timing cover).
2. Disconnect the oil pump from the oil pickup and remove it.
3. Inspect the oil pump for wear; replace if damaged or malfunctioning.
4. Install the new oil pump and tighten to the manufacturer's torque specifications.
5. Reassemble any components removed during access.

4. Clean Oil Passages

• Tools Required: Cleaning solvent, brushes.

1. Disconnect the oil passages from the engine block.
2. Clean each passage thoroughly using cleaning solvent and brushes to remove sludge or blockages.
3. Reconnect the oil passages securely.
