What to Expect at Your Appointment
Bringing your vehicle in for a check engine light concern is straightforward. Here’s how a visit to Christian Brothers Automotive Fischer Crossings works.
Drop Off Without Disrupting Your Day
We offer a complimentary shuttle service so you can get to work, run errands, or head home while we get to work on your vehicle. Your schedule doesn’t need to stop because your car needs attention.
Diagnosis First, Repairs Only With Your Approval
Our technicians connect a scan tool to retrieve stored trouble codes, then inspect the related components to confirm what actually failed before recommending anything. Every vehicle also receives a complimentary Courtesy Inspection during your visit. We explain our findings in plain language, not technical jargon, and nothing is repaired without your permission.
Clear Communication Through Completion
Once you approve the work, we complete the repair and help you understand what was done and why. No surprises on the invoice.
1. Schedule Your Appointment
Whether scheduling online or over the phone be sure and let us know what you're experiencing so we can provide fast and accurate service advice.
2. Diagnostics and Inspections
Drop off your vehicle and the shop will get to work with inspections and diagnostics using the same equipment as the manufacturers to determine issues and next steps.
3. Digital Vehicle Inspection Report and Estimate
Following the diagnosis we will text you a digital vehicle inspection report, containing pictures and videos of our findings and recommendations.
4. Review and Approval
A service advisor will reach out to walk you through the findings and recommendations to determine how you would like to proceed, or you can approve work directly in your DVI.
5. Work Performed or Scheduled
Most work can be completed immediately, or scheduled based on parts and customer availability.
Our Warranty Has You Covered
Most repairs performed at this location are backed by a 3-year/36,000-mile warranty, reflecting our confidence in the quality of our workmanship. When we repair the cause of your check engine light, you can drive away knowing the work is covered.
What’s Really Behind Your Check Engine Light
Not every shop goes beyond the code. Our Full Service Diagnostic Testing is designed to close that gap. When your vehicle comes in, our technicians use OBD-II data as a starting point, then inspect the actual components tied to that circuit before drawing any conclusions. A diagnostic trouble code identifies the system involved, such as an oxygen sensor circuit or a mass airflow sensor fault, but confirming the exact failed component requires hands-on inspection. Replacing a part based only on a trouble code, without verifying the actual failure, can lead to unnecessary repair bills. We verify before we recommend.
For European vehicles, we offer more support. This location has a dedicated Euro technician on site for diagnostic, repair, and maintenance needs on Mercedes, Audi, Volkswagen, and BMW models. These vehicles have manufacturer-specific fault architectures that a generic scanner doesn’t fully interpret, and having someone trained on that complexity on staff means you get an accurate diagnosis instead of a parts-swap guess.
If your check engine light is on, don’t wait to find out why. Call Christian Brothers Automotive Fischer Crossings at (678) 671-3853 and let our team give you a clear answer.
Common Reasons a Check Engine Light Comes On
Several faults show up frequently in check engine light diagnostics. Knowing what to expect can help you understand the repair conversation when you come in.
Common triggers include:
- Loose or faulty gas cap: A missing or damaged cap allows fuel vapor to escape, triggering an evaporative emissions fault and illuminating the light
- Failing oxygen sensor: Oxygen sensors monitor exhaust gases to help the engine run efficiently; a worn sensor skews fuel delivery and can damage the catalytic converter over time
- Mass airflow sensor fault: This sensor measures incoming air volume so the engine can calculate the correct fuel mixture; contamination or failure causes rough running and poor fuel economy
- Ignition coil misfire or worn spark plugs: A weak ignition coil or fouled spark plug can cause an active engine misfire, which may trigger a flashing check engine light rather than a steady one
- Catalytic converter or emissions-system fault: A converter that isn’t reducing emissions efficiently will set a code and, in most cases, fail an emissions test
A steady check engine light generally points to a non-emergency issue to address soon. A flashing light signals something more urgent, like an active misfire, and warrants prompt attention to help avoid engine damage.
Check Engine Light & Coweta County Emissions Testing
Sharpsburg sits in Coweta County, one of 13 Georgia counties where the state requires annual OBD-II emissions testing for eligible gasoline-powered vehicles. If your vehicle has a stored code that triggers the check engine light, it will fail the emissions test automatically until that fault is diagnosed and repaired. Clearing the light with a code reset won’t get you through inspection; the underlying cause has to be fixed. Our check engine light diagnostics address exactly that, so your vehicle is properly prepared for testing, not just temporarily clear.

FAQs
-
Q. "What is the difference between a steadily lit and a flashing check engine light?"A steadily lit light means that a sensor is sending a signal to your vehicle's computer that something is wrong or it could simply mean that the sensor is out. If your check engine light is flashing, however, that means there is a serious issue and you should stop driving immediately.
-
Q. "Why is my check engine light on but nothing seems to be wrong with my vehicle?"If nothing within your vehicle stands out, then it is possible that it is just a minor issue such as a loose gas cap or a bad O2 sensor. It is still recommended to see a mechanic if the light doesn't disappear to check for any larger issues.
-

"Do you offer a warranty?"As part of our Nice difference.® commitment to providing our customers the best auto service experience possible, we also offer a3-year/36,000-mile warranty on all the work that we do.

-
Q. "What to do if your check engine light turns on?"We recommend heading to your local auto shop as soon as you are able. This is typically a sign that there is an abnormality within your engine.
-
Q. "Is it safe to drive your car when the check engine light is on?"It depends. If you are experiencing other noticeable issues with your vehicle, it may be best to pull over. Otherwise, it is typically okay to drive to your local auto shop. You will want to get this checked sooner rather than later to avoid being stranded with a broken-down car.
