my Volkswagen Golf MK7 (2015-2019) oil light is on, what does it mean?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Allow the engine to cool down before starting work.

2. Check and Top Off Engine Oil

• Remove the dipstick and wipe it clean.
• Reinsert the dipstick fully, then remove it to check the oil level.
  • If the level is low, proceed to the next steps.
• If necessary, add the correct type of engine oil (check owner's manual for specifications).

3. Inspect for Leaks

• Visually inspect the engine and surrounding area for oil leaks.
• If leaks are found, identify the source (e.g., oil filter, oil pan, gaskets).

4. Replace Engine Oil and Oil Filter (if necessary)

• Tools Required: Socket set, oil filter wrench, drain pan, funnel, torque wrench.
• Place a drain pan under the oil pan and remove the oil drain plug.
• Allow the old oil to drain completely.
• Replace the oil filter using an oil filter wrench.
• Reinstall the drain plug and torque it to manufacturer's specifications (usually around 20-25 Nm).
• Fill with new oil using a funnel.

5. Check Oil Pressure

• Install the oil pressure gauge in place of the oil pressure sending unit.
• Start the engine and monitor the oil pressure reading.
  • It should be within the specified range (consult the service manual).
• If readings are low, the oil pump may need to be replaced.
