   During the road test the following operating 

conditions must be fulfilled: 

  

  

 

 The coolant temperature must exceed 85 

C. 

  

  

 

 When the temperature is reached, the 

operating conditions Idling, Part throttle, 
Wide open throttle, Overrun must be 
attained several times. 

  

  

 

 At wide open throttle the speed must exceed 

3500 rpm. 

  

  

-  Again check DTC memories of all control 

modules using "automatic test sequence". 

  

  

If no DTC is stored: 

  

  

-  Press 

 -button.

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). 

 Erase DTC memory after repairing malfunction

 DTC code 

 P0113 

 Additional DTC code 

 035 = Malfunction type as a number  

 Intake Air Temperature (IAT) Sensor -G42-- = faulty circuit or malfunction location  

 Signal too high = Malfunction type as text 

 Sporadic Diagnostic Trouble Codes (DTCs) = Diagnostic Trouble Codes (DTCs) that 

are not always present e.g. loose terminal
