Diagnostic Trouble Code (DTC) table: VAG codes and SAE P0 codes

WARNING: This page is about a different car, the 2002 Volkswagen Cabrio, 2001 Volkswagen Cabrio, and 2000 Volkswagen Cabrio. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The DTC overview is listed according to SAE or VAG code.
Explanation of the malfunction types (e.g. "open circuit/short circuit to Ground"):
Scan tool operating instructions
If components are indicated as malfunctioning: First check the wiring and connectors to these components as well as the system Ground connections according to wiring diagram. This is particularly relevant if malfunctions are output as "occurring sporadically" (SP).
Erase DTC Memory after rectifying malfunction (see Diagnostic Trouble Code (DTC) memory ) and generate readiness code again. See READINESS CODE, GENERATING .

VAG 1551 print out (Example)

16497 P0113 035

Intake air temperature sensor -G42

Signal too large

Sporadic malfunction

Explanation:

16497 = DTC
P0113 - Additional DTC (only for USA at present and disregard)
035 = Malfunction type as a number
Intake air temperature sensor -G42- = Faulty current path or incorrect location
Signal too large = Malfunction type as text
Sporadic malfunctions = Malfunctions that are not always present e.g. loose contact

NOTE: Not all VW (VAG) DTCs have an SAE "P" code associated with it.
