Now you can find out what it means with Mk3Love’s new CEL Search tool. Just click the link in the nav above or visit http://www.mk3love.com/cel and you’ll be well on your way to a smoother running Mk3.

Once you get to the CEL Search form, just punch in the P-code or diagnostic trouble code (DTC) that your car is throwing and Mk3Love will go right to work, searching our database of trouble codes and descriptions.

You can also do a search by keyword, like “catalyst,” shown below. Mk3Love will pull up all trouble codes associated with “catalyst” and display them along with the corresponding P-code and DTC.

Thanks go out to Scott Phillips for doing the code work for the application and to Jonathan Rowny for providing the list of trouble codes and descriptions.

The next time you pull a CEL, turn to Mk3Love to help you decipher the code.
