Have you ever had your check engine light come on and wondered what could be wrong? Cars today are like complex computer systems that monitor everything from engine performance to emissions. At M.E. Gene Johnson Garage, we provide professional diagnostics services to help identify issues quickly. If you're in Austin, Marble Falls, or surrounding areas, our pro technicians are here and ready to help get you the answers to your questions at fair prices.

A warning light on your dashboard means your vehicle’s computer system has detected an issue. Without diagnostics, small problems can take a turn for the worse. Our diagnostic services pinpoint the problem, whether related to your engine, transmission, brakes, or electrical system.

When Should You Get Diagnostics

While it’s important to run diagnostics when a dashboard warning light appears, there are other times when a diagnostic test can be beneficial:

• Check that the Engine Light is On
• Strange Noises 
• Car Vibrations
• Decreased Fuel Efficiency
• Vehicle Stalling or Hesitating 
• Before a Road Trip
• Buying a Pre-owned Car or Selling a Car

At M.E. Gene Johnson Garage, we specialize in all makes and models and use the latest diagnostic tools to obtain information from your vehicle. We scan your vehicle’s onboard computer to retrieve trouble codes and identify malfunctions. We always try to provide you with the best cost for repairs and only perform work with your approval.

Our certified technicians use industry-leading diagnostic equipment to provide accurate assessments, ensuring you only pay for what you need.
