       With engine running (under load), the ECM can 
open or close the throttle valve independently of 
the sensor for accelerator pedal position.  
      This means, for example, that the throttle valve 
could be fully opened even though the 
accelerator pedal has only been depressed half 
way. This has the advantage of preventing 
torque losses at the throttle valve.  
      In addition to this, it results in significantly better 
values relative to emissions and consumption 
under certain load conditions.  
      It would be incorrect to think that "E-Gas" 
consists of only one or two component. E-Gas is 
much more of a system containing all 
components that contribute to recognizing, 
controlling and monitoring the position of the 
throttle valve, e.g. sensor for accelerator pedal 
position, throttle valve control module, EPC 
warning lamp, Engine Control Module (ECM).

When indicated on display:  
After pressing Q-button, throttle valve actuator will be switched on without 
current.  
In this condition, the throttle valve will be drawn into an emergency 
position by a mechanical spring, which is located in the throttle valve 
control module. The values supplied by the two angle sensors in this 
emergency position are stored by the Engine Control Module (ECM).  -  Press buttons -0-, -6- and -0- to select "display group number 060" and 
press -Q- button to confirm input.

Notes:  
 
The abbreviation "ADP" in display field 4 stands for Adaptation.
 "ERROR" can be indicated, for example, if the accelerator pedal is not immediately pressed in response to a request by 
the tester or if the accelerator pedal is released while adaptation is running despite the fact that adaptation is not yet
