how to fix low oil pressure in my Volkswagen Golf Eighth Generation (2020-present)

Solution

1. Preparation

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

2. Oil Change

1. Drain the Old Oil:

   • Remove the drain plug using a socket set.
   • Allow the oil to drain completely into a suitable container.
   • Replace the drain plug and torque it to the manufacturer’s specifications (usually around 25 Nm).

2. Replace Oil Filter:

   • Locate the oil filter; use an oil filter wrench to remove it.
   • Lubricate the rubber O-ring of the new oil filter with fresh oil.
   • Install the new filter and tighten it according to specifications (usually hand-tight plus a 3/4 turn).

3. Add New Oil:

   • Use the manufacturer-recommended oil (consult the owner’s manual for specifications).
   • Pour new oil through the oil filler cap and check the level with the dipstick.
   • Start the engine and let it idle for a few minutes, then recheck the oil level, adding more oil if necessary.

3. Replace Oil Pressure Sending Unit

1. Locate the Sending Unit:

   • Identify the oil pressure sending unit, usually near the oil filter or on the engine block.

2. Remove the Old Sending Unit:

   • Disconnect the electrical connector.
   • Use a socket or wrench to unscrew the old sending unit.

3. Install the New Sending Unit:

   • Apply thread sealant to the new sending unit’s threads.
   • Screw in the new sending unit and tighten to specifications.
   • Reconnect the electrical connector.

4. Test and Monitor

• Reconnect the battery and start the engine.
• Monitor the oil pressure gauge and check for leaks around the new filter and sending unit.
