In this article, we will explain how to read these codes using specific software, describe what an OBD socket is, and help you perform OBD diagnosis of your car on your own.

This can be done easily with the inclusion of this port in most new vehicles.<\/p><p>Then, you must open the specific software for your vehicle. For example, if your car is an Audi A3, the software is called \u201c<strong>ECODIS<\/strong>&#8220;.<\/p><p>When you have opened the ECODIS software, go to \u201c<strong>Diagnostic tools<\/strong>\u201c. In this section, there are two tabs: the first is called \u201cError Codes\u201d and the second is called \u201cMiscellaneous\u201d. You need to scroll down until you find the \u201cError Codes\u201d tab and press OK.<\/p><p>Finally, you must enter a series of specific codes on your keyboard.
