Burning smell under the bonnet: possible sources
A burning smell from the engine bay does not identify a particular material or component; oil on a hot surface, a belt or electrics are examples requiring safe distinction.

Burning smell from brakes: causes and when it is dangerous
A burning smell near a wheel after driving may indicate excessive heat or friction; touching the hot disc cannot confirm the cause.

Petrol smell inside the vehicle: dangerous or normal?
Fuel smell inside the cabin deserves assessment even without a visible puddle.

Gasoline smell inside the car: what should you do before investigating?
Safe actions when a leak is suspected, and observations that help a specialist without opening the fuel system.
