DTC table: SAE P0 codes

Note:

The DTC code overview is listed according to SAE or VAG code.

Electronic Power Control "EPC" relevant Diagnostic Trouble Codes (DTCs) are

indicated additionally by the Electronic Power Control (EPC) Warning Light -K132- in
the instrument cluster.

Explanation of the Malfunction types (e.g. "open circuit/short to Ground"):

scan tool operating instructions

If components are indicated as faulty: First check the wiring and connectors to these

components as well as the system Ground (GND) connections referring to Electrical
Wiring Diagrams. If no malfunction can be located, replace component. This is
particularly relevant if Diagnostic Trouble Codes (DTCs) are output as "occurring
sporadically" (SP).
