why does my Volkswagen Golf MK7 (2015-2019) have a burning smell

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, multimeter, flashlight, safety glasses
• Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before inspection.

2. Addressing Leaks

• Locate Leaks: If oil or coolant leaks are found, trace the source.
• Repair or Replace: Fix the source of the leak (e.g., replace gaskets, seals, or hoses).

3. Replacing Worn Components

• Inspect Belts and Hoses: If any components are worn or damaged, remove them.
• Replace: Install new belts and hoses with manufacturer-specified parts.
• Torque Specifications: Ensure all components are secured to the manufacturer's torque specifications.

4. Electrical Issues

• Inspect Wiring: Look for melted or frayed wiring. Use a multimeter to check for shorts or open circuits.
• Repair or Replace Wiring: Replace any damaged wiring and ensure proper insulation is restored.

5. Oil Change (if necessary)

• Drain Old Oil: Remove the oil drain plug and drain the old oil into a suitable container.
• Replace Oil Filter: Remove the old oil filter and install a new one.
• Refill Engine Oil: Add new engine oil as specified in the owner's manual.
