Site Instructions:

  1. Please note the list of automobile manufacturers at the left edge of the screen. The currently selected ODB code is for the Audi family of autos. The codes for any particular vehicle make and model will be found under the manufacturer family, i.e. Dodge and Plymouth are part of the Chrysler family of cars and trucks.

  2. Also notice that just to the right of the manufacturer family list is a short group of OBD II codes. The highlighted Audi OBDII code P1504 in this list is the currently selected code, and the information on this page pertains to trouble code P1504. The other codes in the list above and below this code are OBD II codes some of which may be related to the current fault code and can be navigated to directly.

  3. Need to look up additional OBD II Trouble Codes, use the search box. Enter the 5 character trouble codes in the search box and submit the search. You can repeat the search as many times as you need, one diagnostics code per search.

  4. Don't assume a particular OBD2 code means the same for other auto manufacturers as there are many manufacturer specific codes in use.

  5. If your trouble codes are for a different auto family, select that vehicle series before searching for the diagnostics codes because not all OBD II codes used by one manufacture are used by the other manufactures. The search only looks at OBD codes valid for the currently selected manufacturer family.

  6. If your automotive family is grayed out, the current OBD code, P1504, is not among those used by the current manufacturer. You can click un-gray at the bottom of the auto family list and then select the manufacturer for your vehicle before searching for your fault codes.
