Check Engine Light

Get Answers You Can Trust at Complete Automotive Services

Seeing your check engine light turn on can be stressful — especially when your car still seems to be driving fine. At Complete Automotive Services, we provide accurate, reliable check engine light service in Austin, MN, helping local drivers understand what’s going on and what needs to be done next.

Whether the light just came on or has been glowing for a while, our technicians can diagnose the issue and explain your options clearly.

Why Is My Check Engine Light On?

Your check engine light is your vehicle’s way of telling you something isn’t operating as expected. Sometimes it’s a minor issue, and other times it’s a warning that needs immediate attention.

Common reasons your check engine light may turn on include:

• Loose or faulty gas cap

• Failing oxygen sensor

• Worn spark plugs or ignition coils

• Emissions system problems

• Mass airflow sensor issues

• Engine or transmission performance concerns

Even if your vehicle seems to be running normally, it’s important not to ignore the warning.

What to Do When the Check Engine Light Comes On

Not all check engine lights mean the same thing.

• Solid check engine light:
  The vehicle likely needs attention soon, but it’s usually safe to drive for a short time.

• Flashing check engine light:
  This indicates a more serious issue that could cause engine damage. You should have your vehicle checked as soon as possible.

If you’re unsure what your vehicle is telling you, we’re here to help.

Complete Check Engine Light Diagnostics

At Complete Automotive Services, we service all makes and models, including cars, trucks, SUVs, and light-duty diesel vehicles. We don’t guess — we diagnose.

Computer Diagnostics

We connect professional diagnostic equipment to your vehicle to read trouble codes and analyze system data. This gives us a starting point for identifying the problem.

In-Depth System Testing

A code alone doesn’t tell the full story. We perform additional testing to determine the actual cause of the issue, not just the symptom.

Clear Repair Recommendations

Once we identify the problem, we explain what’s happening, what needs to be fixed, and what can wait — so you can make an informed decision.

Why Prompt Diagnosis Matters

Ignoring a check engine light can lead to reduced fuel economy, poor performance, and more expensive repairs down the road. What starts as a small sensor issue can turn into engine or emissions system damage if left unresolved.

Timely check engine diagnostics help:

• Prevent further engine damage

• Improve fuel efficiency

• Reduce emissions

• Restore proper performance

• Give you peace of mind
