how to fix low oil pressure warning in my Volkswagen Golf MK7 (2015-2019)

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a flat surface and that the engine is cool.
• Disconnect the battery to ensure safety while working on electrical components.

2. Change Engine Oil and Filter

1. Place a drain pan beneath the oil pan.
2. Remove the oil drain plug using a socket wrench and allow the old oil to completely drain.
3. Replace the oil drain plug and tighten it to the manufacturer’s specified torque (typically 25-30 Nm).
4. Remove the old oil filter using an oil filter wrench.
5. Clean the mounting surface on the engine where the filter attaches.
6. Apply a small amount of fresh oil to the rubber seal of the new oil filter and install it by hand until snug, then tighten it further according to specifications (usually 3/4 turn after contact).
7. Fill the engine with new oil through the oil filler cap, using the recommended oil type (usually 5W-30 or 0W-30 for the MK7).
8. Start the engine and allow it to run for a few minutes, checking for leaks around the filter and drain plug.

3. Replace Oil Pressure Sending Unit (if necessary)

1. Locate the oil pressure sending unit, typically found near the oil filter or on the engine block.
2. Disconnect the electrical connector from the sending unit.
3. Remove the sending unit using a socket or wrench, being careful not to damage surrounding components.
4. Install the new oil pressure sending unit and tighten to the manufacturer’s specifications (usually around 20 Nm).
5. Reconnect the electrical connector.
