Potential Causes:
  1. Oil Leak: Oil leaking onto hot engine components can cause a burning smell.
  2. Coolant Leak: Coolant may leak onto hot engine parts, leading to a sweet burning smell.
  3. Worn Brake Components: If the smell is more pronounced when driving, it could be overheated brake pads.
  4. Electrical Issues: Burnt wiring or electrical components can produce a burning smell.
  5. Clutch or Transmission Issues: If a manual transmission or hybrid system is involved, the clutch may be slipping, causing burning smells.
Repair Instructions:

If Oil Leak is Found:
