my Volkswagen Golf MK5 (2004-2008) smells like burning rubber, what could it be?

Solution

1. Preparation

• Tools Required: Safety glasses, gloves, flashlight, OBD-II scanner.
• Ensure the vehicle is parked on a flat surface and the engine is cool. Disconnect the battery for safety before starting any repairs.

2. Inspect and Replace Serpentine Belt

1. Remove the Engine Cover (if applicable):
   • Unscrew any fasteners holding the cover in place.
   • Carefully lift the cover off and set it aside.
2. Inspect the Serpentine Belt:
   • Look for cracks, fraying, or signs of burning.
   • Check for proper tension and alignment on the pulleys.
3. Remove the Old Serpentine Belt:
   • Use a wrench to relieve tension on the belt tensioner.
   • Slide the belt off the pulleys and remove it.
4. Install New Serpentine Belt:
   • Route the new belt according to the belt routing diagram located near the engine bay.
   • Ensure it is properly seated on all pulleys and adjust the tensioner as needed.

3. Brake System Inspection and Service

1. Inspect Brake Components:
   • Remove the wheel to access the brake assembly.
   • Check brake pads for wear; replace if they are thin or worn unevenly.
   • Inspect calipers for any signs of sticking or overheating.
2. Replace Brake Pads (if necessary):
   • Remove the caliper bolts and lift the caliper off the rotor.
   • Remove the old brake pads and clean the caliper bracket.
   • Install new brake pads and reattach the caliper securely.
3. Reassemble Wheel and Test:
   • Reinstall the wheel and lower the vehicle.
   • Repeat with the other wheels if necessary.
