- Fuel leak: A fuel leak is a common cause of petrol smell in cars. Check the fuel lines, fuel tank, and fuel pump for any leaks. If you find a leak, it is important to have it repaired immediately to avoid a fire or other hazards.
- Faulty fuel injection system: A faulty fuel injection system can cause the engine to run rich, which means that it is using more fuel than necessary. This can result in a strong petrol smell from the exhaust.
- Carbon canister: The carbon canister in your car is designed to capture fuel vapours from the fuel tank and prevent them from escaping into the atmosphere. If the carbon canister is damaged or blocked, it can cause a petrol smell in the car.
- Faulty ventilation system: A faulty ventilation system can cause petrol fumes to build up inside the car. Check the air filter and the ventilation ducts to make sure that they are clear and unobstructed.
- Engine overheating: An engine that is running too hot can cause the fuel to vaporize and create a petrol smell. Check the coolant level and the thermostat to make sure that the engine is operating at the correct temperature.
If you smell petrol in your Citroën Xsara Picasso, it is important to take it to a mechanic to have the problem diagnosed and repaired as soon as possible.
