Full Service Diagnostic Testing for Lakeway Drivers

When your check engine light comes on, you need more than a quick code read. At Christian Brothers Automotive Lakeway, our ASE-certified technicians use Full Service Diagnostic Testing and manufacturer-quality equipment to go beyond basic ODB scanner codes and pinpoint what’s actually triggering your vehicle’s malfunction indicator lamp. We’ve spent more than 34 years building a reputation for honest, thorough service, and we’ve been ranked #1 in Customer Satisfaction Among Aftermarket Full-Service Maintenance and Repair Providers in the J.D. Power 2025 Aftermarket Survey Index (ASI) Study for the sixth consecutive time. For J.D. Power’s 2025 award information, visit jdpower.com/awards.

That light could signal anything from a loose gas cap to a more serious engine or emissions issue. Knowing the code isn’t the same as knowing what’s wrong. Our Check Engine Light Services are built around giving you the full picture, so you can make confident decisions about your vehicle.

What Sets Christian Brothers Automotive Lakeway Apart

Every vehicle that comes through our doors gets a complimentary Digital Vehicle Inspection (DVI): real photos and videos of your vehicle’s condition and our recommendations, sent directly to your phone as a text. You see what our technicians see. No surprises, no jargon.

Before any repair begins, a service advisor walks you through the DVI report, answers your questions, and talks through your options. You approve the work. Nothing happens without your sign-off.

We also include a complimentary Courtesy Inspection covering lights, brakes, suspension, tires, and battery with every visit. And when the repair is complete, it’s backed by our Nice difference.® Warranty: 3-year/36,000-mile coverage, whichever occurs last, honored at any Christian Brothers Automotive location nationwide.

How Check Engine Light Services Work at Christian Brothers Automotive Lakeway

Your vehicle’s onboard diagnostic system (OBD-II) monitors the engine, transmission, emissions controls, and other key systems. When something falls outside normal parameters, the system stores a diagnostic trouble code (DTC) and turns on the light. Reading that code tells you where to look. Full Service Diagnostic Testing tells you what’s actually wrong.

Here’s how the process works at our Lakeway location:

  • Schedule Your Appointment: Call us or book online at your convenience
  • Diagnostics and Inspections: Our ASE-certified technicians use manufacturer-quality equipment to diagnose the issue and determine the right next steps
  • Digital Vehicle Inspection Report and Estimate: We text you a DVI report with photos and videos of our findings and recommendations
  • Review and Approval: A service advisor walks you through everything; no work is performed until you approve it
  • Work Performed or Scheduled: Many repairs can be completed during the same visit; if parts or timing require otherwise, we’ll schedule a time that works for you

We also work with all major extended warranty providers. If your vehicle is covered, confirm eligibility when you schedule, and we’ll coordinate the rest.

Flashing vs. Solid Check Engine Light

Not all check engine lights carry the same urgency. A steady light means your vehicle’s onboard diagnostic system has detected a problem. In many cases, it’s still safe to drive to the shop, but prompt service is important. Delaying can affect fuel economy and performance, and minor issues can turn into larger ones.

A flashing check engine light is a different situation. It typically indicates an active engine misfire, which can damage the catalytic converter and create a safety risk. If your light is flashing, don’t ignore it. Bring the vehicle in as soon as possible.

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.
  • Q. "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. We offer this warranty at every Christian Brothers Automotive nationwide, and it will be honored at any location, regardless of which branch did the initial work.
  • Q. "Can you provide service under my extended warranty?"
    Yes. At Christian Brothers Automotive, we work with all major extended warranty providers to make needed repairs for our customers. If you have an extended warranty, you can discuss your carrier with our team when scheduling an appointment and confirm that the work will be covered. You can find a partial list of the extended warranty companies we work with here.
  • 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.
