my Volkswagen Tiguan First Generation (2007-2018) has a burning smell

Solution

1. Preparation

• Gather necessary tools and parts before starting.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fluids

• Engine Oil:
  • Remove the oil drain plug and allow oil to drain into a pan.
  • Replace with manufacturer-recommended oil; torque the drain plug to specified value.
• Coolant:
  • Drain the coolant from the radiator and engine block.
  • Refill with a 50/50 mix of manufacturer-recommended coolant and water.

3. Replace Damaged Components

• Belts and Hoses:
  • Remove any damaged belts or hoses by loosening tensioners and clamps.
  • Install new belts and hoses, ensuring they are properly tensioned and secured.
• Wiring:
  • Inspect wiring for any burnt sections; repair or replace as necessary.
  • Use heat-shrink tubing to insulate repaired wires.

4. Reassemble and Test

• Reconnect the negative battery terminal.
• Start the engine and monitor for any further burning smells or abnormal sounds.
• Allow the vehicle to reach operating temperature while checking for leaks.
