175 distinct codes across 196 real Volkswagen diagnostics.
175 distinct codes across 196 real diagnostics on Volkswagen, including the Volkswagen-specific ones no generic code list can decode.
Volkswagen-specific codes
These are manufacturer-specific, which means the same code on another marque is a different fault. That is exactly why they have no page of their own and no entry in any generic code list. Scoped to Volkswagen and ranked by how often we have actually seen them, they are a claim we can stand behind.
