Audi OBD-II (OBD2) port can be used to troubleshoot the vehicle, install tracking, or monitoring device.
In this guide, we explain what an Audi check engine light means and go over the common problems that may trigger an Audi Check Engine Light (CEL).
You will also find step-by-step instructions on reading Audi check engine light codes yourself using an OBD-II scanner.
Here are a few things you may notice when your Audi check engine light turns on.
If the problem is less serious, you may not notice any symptoms except the check engine light. Even if you don't notice any symptoms, diagnose your Audi as soon as possible.
If your Audi check engine light stays on, it means the On-Board Diagnostic (OBD) system has detected a problem. Fault codes, often referred to as Diagnostic Trouble Code or DTC, gets stored in the Engine Control Unit (ECU).
The problem could be emissions-related such as a loose gas cap, but it can also indicate a serious problem such as a faulty transmission valve body.
If your Audi check engine light comes on and there are no other symptoms, the first thing that you should do is tighten the gas cap.
If your Audi check engine light doesn't reset within three to four days, it is time to read the codes. See the instructions below.
This is a list of common problems that will trigger the Audi check engine light to come on.
Follow these steps to read the check engine light on any that's the model year 1996 or newer.
For this procedure, you can use a generic OBD-II scanner, but an Audi OBD-II scanner that will read Audi manufacturer codes is recommended.
We don't recommend clearing the Audi check engine light without fixing the problem.
First, you need to read the codes. Figure out why the CEL turned on and fix the problem.
Once you find what caused your Audi check engine light to come on and fix the problem, you can use the OBD-II scanner to clear the code as long as no other codes are present.
These instructions work on all 1996 and newer Audi vehicles, including the A1, A3, A4, A5, A6, A7, Q3, Q5, Q7, and TT models.
If your Audi check engine light is flashing, it indicates an engine misfire, which means fuel is not getting burnt efficiently in the cylinders.
Engine shaking is often caused by a worn spark plug, bad ignition coil, Ignition Control Module (ICM), or bad catalytic converter.
