my Volkswagen Golf MK7 (2015-2019) has low oil pressure warning, what should I do?

Solution

1. Preparation

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

2. Change Engine Oil

• Sub-steps:
  1. Remove the oil drain plug using a socket wrench and allow the old oil to drain completely into a pan.
  2. Replace the oil drain plug and torque it to the manufacturer’s specification (typically around 20-25 Nm).
  3. Remove the old oil filter using an oil filter wrench.
  4. Apply a thin layer of new oil to the rubber gasket of the new filter.
  5. Install the new oil filter and tighten it according to the manufacturer’s specifications (usually hand-tight plus ¾ turn).

3. Replace Oil Pressure Sending Unit (if faulty)

• Sub-steps:
  1. Locate the oil pressure sending unit, typically found near the oil filter.
  2. Disconnect the electrical connector from the sending unit.
  3. Remove the sending unit using a socket or wrench.
  4. Install the new oil pressure sending unit and torque it to the manufacturer's specifications.
  5. Reconnect the electrical connector.

4. Add New Oil

• Sub-steps:
  1. Pour the recommended type and amount of new oil into the engine through the oil filler cap (consult the owner's manual for specifications).
  2. Start the engine and let it run for a minute to circulate the oil.
  3. Check the oil level again with the dipstick and add more oil if necessary.
