Notes:

  • ◆ The fault code overview is listed according to SAE or V.A.G code.
  • ◆ Explanation of the fault types (e.g. "open circuit/short circuit to earth"):

=> Fault reader operating instructions

  • ◆ If components are indicated as faulty:
    First check the wiring and connectors to these components as well as the system earth connections according to current flow diagram. This is particularly relevant if faults are output as "occurring sporadically" (SP).
  • ◆ Erase fault memory after rectifying fault .

V.A.G 1551 print out, e.g.:

16497 P0113 035

Intake air temperature sender -G42

Signal too large

Sporadic fault

Explanation:

  • ◆ 16497 = Fault code
  • ◆ P0113 = Additional fault code (only for USA at present and disregard)
  • ◆ 035 = Fault type as a number
  • ◆ Intake air temperature sender -G42 = Faulty current path or incorrect location
  • ◆ Signal too large = Fault type as text
  • ◆ Sporadic faults = Faults that are not always present e.g. loose contact
