Solution

1. Preparation

Tools Required: Jack and jack stands, tire iron, OBD-II scanner, flashlight, gloves.
Ensure the vehicle is parked on a flat surface and the engine is turned off. Allow the engine to cool if it has been running.

2. Inspect and Replace Engine Belts

Sub-steps:
- Visual Inspection: Check the serpentine belt and timing belt for cracks, fraying, and proper tension.
- Tension Adjustment: If the belt is loose, adjust the tensioner according to the manufacturer's specifications.
- Replacement: If damage is found, remove the old belt by loosening the tensioner and install a new belt, ensuring proper alignment.

3. Inspect and Replace Tires

Sub-steps:
- Tire Inspection: Check for uneven wear or damage on all tires.
- Pressure Check: Ensure tires are inflated to the recommended pressure.
- Replacement: If tires are damaged or excessively worn, replace them with new tires of the appropriate size and type for the Tiguan.

4. Examine Under-hood Components

Sub-steps:
- Visual Inspection: Check all hoses and wires for signs of melting, damage, or excessive heat.
- Replacement: If any components show signs of damage, replace them with OEM or equivalent parts.

5. Clean Up and Test

Sub-steps:
- Clean Residue: If any rubber or oil residue is found on hot components, clean it off with a suitable degreaser.
- Test Drive: After repairs, test drive the vehicle to ensure the smell has dissipated and no performance issues are present.
