Related Tests, Information and Procedures
NOTE:
- The DTC table is organized according to SAE and VAG diagnostic trouble codes.
- "E-Gas"-relevant malfunctions are also indicated by the MIL for electric accelerator mechanism ("EPC warning lamp").
- Further information on the malfunction types (e.g. "Open/Short circuit to Ground) See Scan Tool operating instructions
- If components are designated as faulty: First check wiring and harness connectors for these components as well as Ground (GND) wiring for the system according to wiring diagram. Do not replace component unless there are no malfunctions found here. This is particularly valid when malfunctions are displayed as "sporadically occurring" (SP).
- Erase DTC memory after repairing malfunction. Reading Diagnostic Trouble Codes
Example printout on VAG1551 printer:
16497 P0113 035
Intake Air Temperature (IAT) sensor -G42-
Signal too large
sporadic malfunction
Explanation:
- 16497 = DTC
- See P0113 = additional trouble code (only for USA at present)
- 035 = malfunction type as number
- Intake Air Temperature (IAT) sensor -G42- = faulty circuit or malfunction location
- Signal too large = malfunction type as text
- sporadic malfunction = malfunction not always present, e.g. loose contact
