Audi Check Engine Light – Service Engine Light

What is a check engine light?

Have you ever started up your vehicle or been simply driving down the road and suddenly you see a colorful glowing object staring back at you from your dash? What is that thing? Yes, it’s an icon that says “Check Engine Light”, but what exactly do you need to check? It’s never a good time to receive this message from your vehicle. Suddenly your mind begins to race and you wonder if it’s safe to drive your vehicle? Or if your vehicle might break down? And, how much might this cost me?

Don’t panic, It’s your Check Engine Light – Service Engine Light. Your Audi’s way of alerting you to a potential needed repair. This icon is notably the most misunderstood indicator on your dashboard. It can be illuminated by something as simple as a loose gas cap or as serious as a misfiring or overheating engine. It does not mean you should cancel your dentist appointment or miss little your sons basketball game. However, you should get it checked as soon as possible. As long as the icon is not flashing, or on some models, turned from yellow/orange to red and your gauges read normal, it is generally fine to drive your vehicle. Be sure to check your gauges first. Good news, you can still make that dental appointment!

Today’s vehicles have numerous modules and hundreds of sensors that monitor systems throughout your vehicle. It is said that the vehicle you drive today has more onboard computers than the Apollo 11. Yikes! When the On-Board Diagnostics (OBD) system finds a concern, it monitors and corrects it when possible. It can do this by adjusting timing, fuel mix, engine speed, and it may even adjust transmission shift patterns and engine power. The Electronic Control Module, the vehicle’s “brain” (ECU or ECM as it is called) can put your vehicle into “Limp” mode if the readings it is gathering from the OBD indicate potential harm to major components such as the engine or the transmission. Very impressive!

WHAT SHOULD I DO IF THIS ICON POPS UP ON MY DASH? 

Steps to possibly solve the Check Engine Light -Service Engine Light

  • Check your gauges: Oil pressure and engine temperature (Coolant). DO NOT drive your vehicle is these gauges are showing abnormal readings
  • Check your gas cap: A loose or defective cap can cause your check engine light -service engine light to turn on. Tighten it at least three clinks. Keep in mind if your cap was loose, your check engine light may not immediately reset. Sometimes not even until the next day. It takes several “clear of code” trips in order to reset.
  • Reduce engine speed or load: If illumination occurs while driving reduce your speed, and you may want to pull over to check things out for peace of mind.
  • Have your vehicle scanned for trouble codes: There are several places that you can have your vehicle scanned for trouble codes. Most auto parts stores will scan for free. Keep in mind they are using a very basic scanner and do not employ factory trained technicians. Your vehicle will need to be assessed by a professional.
