Exhaust and Emissions Repair

When you start your engine, it makes a lot more noise than you might think. It sounds quieter because of your exhaust system. But the exhaust system doesn’t just help quiet the noise you hear from your engine. It also channels the high-temperature and often harmful exhaust gases through the underside of your vehicle, releasing them safely out the back.

However, the exhaust system doesn’t operate on its own. When the poisonous gases pass through your car, they also travel through a series of filters and other systems that help recycle them into non-hazardous gases. This is your emissions system at work.

At Bosch Auto Service, we use premium, high-quality mufflers and other exhaust vehicle parts to ensure your safety and the continued safety of the environment around you. We’ve watched over 125 years as exhaust and emissions regulations and technologies have changed. You can trust your service technician to fully understand your vehicle’s exhaust needs.

Trouble with Your Exhaust or Emissions?

Your vehicle’s exhaust and emissions systems help keep you safe and the environment clean. If there’s a problem with any part of the system, such as failing your emissions test, it’s important to see a qualified mechanic to rectify the issue as soon as possible.

The Exhaust Emissions System

The emissions system performs three crucial functions in your vehicle. First, it helps ensure that your car is producing low levels of exhaust gases that could otherwise harm both you and the environment. Your emissions system also reduces the amount of noise your vehicle makes, providing a more comfortable ride. A well-working emission system will also help improve your engine’s overall performance and consumption.

Signs of Exhaust Emission Failure

The most common indication of an issue with your vehicle’s exhaust emission system is failing to pass your emissions test. These tests check to confirm that your emissions system is working properly to recycle the harmful gases your engine produces. However, since an emissions test is only required every couple of years, there could be something wrong with your system before you get the test done. Other signs of exhaust emission failure include:

  • The check engine light turning on
  • Decreased gas mileage
  • Unusual noises when operating
  • Scent of fumes inside the car
If you notice any of these symptoms, it’s important you have your car inspected by a qualified exhaust and emissions mechanic.

Causes of Exhaust Emission Failure

The reason most vehicle systems fail is that they are old and worn or not well maintained. Your exhaust and emissions systems need regular maintenance to ensure they are running efficiently. If there’s a problem with one of the parts, your vehicle’s exhaust emissions could contain excessive amounts of hazardous gases, such as carbon monoxide. Causes of exhaust emission failure include:

  • Faulty ignition system
  • Damaged or missing catalytic converter
  • Vacuum system leak
  • Faulty oxygen sensor
While these contribute directly to issues in your exhaust and emissions system, you may also find your vehicle failing to pass your emissions inspection even if there’s not a problem with the system itself. Being overdue for an oil change or having a dirty air filter may also prompt a failure of your test.

Emissions Test Regulations

Getting your emissions test for your vehicle is required every few years. The specific testing regulations and passing metrics vary by state to state. You’ll need to pass the emissions test for the state that your vehicle is registered in, even if you’re not currently driving in that state.

The emissions test puts vehicles under four categories, each with their own, separate rules and regulations. Most standard vehicles will fall under the light-duty category. This category represents any vehicle at or below 14,000 pounds GVWR (Gross Vehicle Weight Rating). For vehicles over 14,000 pounds, they must pass the heavy-duty vehicle emissions test. There’s also a separate category for motorcycles, and a final category for all off-highway motorcycles and all-terrain vehicles.

When you fail an emissions test, you’ll receive a report specifying with regulation your vehicle failed to pass. You can view the specific regulations and their consequences, or bring your failure report to your Bosch Auto Service technician for assistance.

Why You Should Repair Your Exhaust and Emissions Systems

Your exhaust and emissions systems work together to help filter the gases that form in your vehicle’s combustion chamber. If they fail to work, you could be pumping hazardous gas into the environment around you or even into the car itself as you drive. Keeping yourself safe and the environment healthy is the responsibility of every car manufacturer and driver. If you notice something off with your exhaust or emissions system, don’t wait until your next emissions test to get it inspected and repaired.

Why did my car fail its emissions test?
Even if your exhaust and emission system is working perfectly, your vehicle can still fail its emissions test if there’s another issue. When your car fails an emissions test, you’ll get a report indicating the potential problems it picked up on. Your Bosch Auto Service mechanic can use this report to identify any issues in your vehicle and make the necessary repairs.
Can I still drive if I fail an emissions test?
In most states, a vehicle that fails its inspection isn't allowed to be driven because faulty exhaust emission systems negatively impact the environment. There will be a set period of time during which you can still operate your vehicle, but you will need to repair and retest it before that period expires.
