Why is the Check Engine Light On in My Audi?

We've all been there. Cruising the city lights, highways, and back roads of Riverside County, a warning light appears on your Audi dashboard. It reads: Check Engine. Don't panic. The cause of its illumination could be something as mundane as a gas cap that's come loose. First off, check your gas cap. If it needs tightening, do so. After two to three days of regular driving, your check engine light should turn off. However, this isn't always true; if it doesn't, something else is up.

If you've noticed lately, for instance, that your fuel economy isn't what it used to be, that your car or SUV doesn't seem as powerful, that your engine shakes, or that your transmission just won't change gears, you could have a more serious engine or transmission problem on your hands. It's even more unnerving that many operational problems can present with no symptoms at all. There are some common causes for a check engine light coming on, though.

  •  Oxygen sensor malfunction or failure
  • Worn-out spark plugs
  • Ignition coil and coil pack problems
  • An air intake system leak
  • A faulty catalytic converter
  • The use of low-quality gas
  • A turbocharging issue
  • A problematic ignition control module
