Why is My Check Engine Light On?

  • Loose or Faulty Gas Cap: A common and simple issue that can cause the light to appear.
  • Oxygen Sensor Failure: A malfunctioning sensor can impact fuel efficiency and emissions.
  • Faulty Catalytic Converter: A critical component that helps reduce harmful emissions.
  • Mass Airflow Sensor Issues: Affects air intake and engine performance.
  • Worn or Faulty Spark Plugs and Ignition Coils: Can cause misfires and reduced engine performance.
  • Battery or Alternator Problems: Electrical system issues may trigger the warning light.
  • Engine or Transmission Issues: More severe problems requiring immediate attention.

What Our Customers Are Saying

From Michael Enshaie: “01 BMW 330ci, Check engine light came on. Took it to the shop and Rick had it checked out. I was told it’s just a warning and no repairs were needed. I was not even charged the diagnostic fee. They even gave me a ride back home while the car was in the shop. Several days later, the light reset itself and everything is back to normal. I call this honesty and outstanding service that is very hard to find elsewhere.

Michael’s experience highlights our honest and transparent approach. If your check engine light comes on, we’ll give you a clear diagnosis—no unnecessary repairs, just expert guidance.

From Mark Teixeira: “I’ve been taking my 6 Series there for about four years. Anyone who owns one of these knows they are expensive to maintain. AGA really knows how to deal with these cars. Let me put it this way—before taking it to AGA, my check engine light was mostly on, no matter who worked on it. It would stay off for at most two months. In four years taking it to AGA, it hasn’t been on once. They are thorough the first time.

Mark’s story showcases our expertise in diagnosing and repairing check engine light issues the right way—ensuring long-term solutions instead of temporary fixes.
