About exhaust fumes:

A leaking exhaust

Have you noticed a constant smell of exhaust gases inside your car? Leaking exhaust fumes can be dangerous to your health as well as the health of your exhaust system. For this reason, the cause of the exhaust fumes should be diagnosed and fixed as soon as possible. 

Your car’s exhaust system is responsible for processing, filtering and expelling excess fumes from your engine. If the fumes are finding their way into the interior of your car, it is likely that part of your exhaust system has developed a leak, and the fumes are finding their way into your car’s interior cabin. 

Since exhaust fumes contain harmful gases, they can often cause drivers to feel unwell or get headaches. Leaking exhaust fumes are also very flammable and can be a fire hazard. For this reason, it is important that the fault in your exhaust system is serviced quickly. If you absolutely have to drive with a leaking exhaust, we recommend that you:

  • Drive with the windows down.
  • Drive conservatively, avoiding revving the engine to high levels.
  • Stop if the smell is becoming more powerful.

Causes of exhaust fumes in the cabin:

Exhaust fumes entering the interior of a car can be caused by several factors, including:

  1. Cracks or leaks in the exhaust system: Cracks in the exhaust pipes, muffler, or other parts of the exhaust system can allow exhaust fumes to enter the car. This is a common problem in older vehicles with rusting or corroded exhaust systems.
  2. Loose or disconnected exhaust parts: If any parts of the exhaust system are loose or disconnected, it can cause exhaust fumes to leak into the car.
  3. Leaks in the cabin air intake: The cabin air intake system is designed to bring in fresh air from outside the vehicle. If there is a leak in this system, it can allow exhaust fumes to enter the car.
  4. Faulty exhaust gas recirculation (EGR) valve: The EGR valve is designed to recirculate a portion of the exhaust gases back into the engine to reduce emissions. If the valve is defective, it can allow exhaust fumes to enter the car. Problems with the valve are often caused by a faulty sensor.
  5. Faulty catalytic converter: The catalytic converter is designed to reduce harmful emissions from the vehicle. If it fails, it can allow exhaust fumes to enter the car.

If you suspect that your vehicle is suffering from exhaust fumes entering the interior, it is important to have it inspected by a qualified mechanic as soon as possible. Inhaling exhaust fumes can be harmful to your health, and the problem can also indicate a more serious issue with your vehicle.
