Emissions and Smog Testing
At Carolina Auto Repair and Service, we help our Clayton customers' cars run as cleanly and efficiently as they possibly can. We provide a range of emissions testing services to ensure that your car is running and driving its best, as well as complying with all local smog regulations. Should a problem arise with any of your vehicle's emission systems, we provide the parts and expertise to get you back on the road. Carolina Auto Repair and Service can replace mufflers/catalytic converters, refill diesel exhaust fluid, and make sure the full range of filters in your vehicle's exhaust system are working perfectly.
Regulators understand that older cars simply can't meet modern emissions standards without extensive modifications. For newer cars however, passing a smog test is a requirement of road legality. Call us at 919-737-2277 to learn more about the emissions requirements for your vehicle.
Emissions testing (also known as smog testing) is a vital part of the maintenance of your vehicle. E-tests provide your mechanic with important information about your car's engine and exhaust system. If important components, like your car's catalytic converter aren't working properly, the car isn't running as it was intended to by the manufacturer. Inefficiency costs you extra money in fuel and does unnecessary harm to the planet. Emissions testing can also affect the value of a vehicle you're trying to sell; while you can still sell a car without a valid e-test certification, you'll get more money for one that has passed the test.
There are several reasons that a car may fail its emissions test. There may be a problem with the vehicle's fuel system adding too much fuel to the air-fuel ratio required for proper combustion within the cylinders of the car's engine. This is known as "running rich" and results in the smell of gasoline from fuel passing through the engine and exhaust system without being fully burnt. Causes of this issue range from faulty fuel injectors to issues with the engine's control computer. There may also be problems with oxygen sensors or the vehicle's ignition system. At Carolina Auto Repair and Service, we use a complete set of diagnostic equipment to determine the problem and fix it quickly, explaining every step of the process to you, our valued patron. Call us at 919-737-2277 or send us an email to arrange a health check for your car's emissions system today!

What Our Customers Are Saying
Super easy to work with. Got text updates about what they were doing, suggested work, stuff they checked that was all good, and when it was ready. They were polite and efficient. Definitely going back.

I schedule my oil changes here. Call in advance checking for availability bc Clayton is growing and the wait can sometimes take a while. More often than none i seem to be able to drop my car off in the morning and it's completed by the afternoon. Alerts and updates are sent via text which is convenient bc I have meetings throughout the day so one less call is amazing. The staff are always polite and easy to have auto discussions too.
