OBD-II, EOBD and VAG trouble code definitions

What is this?

This is an online library of EOBD, OBD-II and VAG (VW Audi Group) automotive fault code definitions.

We currently have more than 21,000 code definitions within our database, and it is still growing.

Got a fault code on your car? See if we can help find you a definition...

Which makes do we cover?

Our database currently includes both generic definitions and manufacturer-specific definitions.

Generic definitions apply to all manufacturers, i.e. the same code will mean the same whether on a BMW or a Ford car.

Manufacturer-specific definitions are unique to a particular manufacturer (and sometimes to a particular model).

Can't find the diagnostic port?

Paying subscribers can now also access our database of diagnostic port locations - complete with photos for many vehicles.

Our port location database is new, but growing rapidly...
