1. Learning of the throttle valve stop



Warning!Communication with ECU required.



0217



M16/6 (Throttle valve actuator) : The throttle valve is jamming or is stiff. (P2176)



Possible cause:



- M16/6 (Throttle valve actuator)



Affected functions:



- Engine diagnosis



- Engine running



-------------------------------------------------



Test 1: Check component M16/6 (Throttle valve actuator).



1. Check component M16/6 (Throttle valve actuator).



Test 1.1: Check component M16/6 (Throttle valve actuator) using actual value.



Test 1.2: Check component M16/6m1 (Actuator motor) by means of actuation.



Test 1.3: Perform mechanical inspection of component M16/6 (Throttle valve actuator).



Test 1.4: Note : Control unit programming must be performed on control unit variants VC6 to VC8.



1.1. Check component M16/6 (Throttle valve actuator) using actual value.



Warning!Communication with ECU required.



1.2. Check component M16/6m1 (Actuator motor) by means of actuation.



Test prerequisite



- Operate engine at idling speed.



Note



- If the throttle valve angle is< 1,1锟斤拷, unmetered air may be present.



Status of relevant actual value:



- Throttle valve angle:Warning! Communication with ECU required.



Move on to actuation with button F2



1.3. Perform mechanical inspection of component M16/6 (Throttle valve actuator).



Test sequence



- Switch off ignition.



- Expose component M16/6 (Throttle valve actuator).



- Slowly operate throttle flap by hand up to full load.



Specified value



- The throttle valve must not stick and must close by internal spring force.



Question



- Is the test o.k?



YES



The test is o.k..End of test



NO



The test is not o.k..Possible cause and remedy



- Check intake tract for residue and clean if necessary.If no residue is present, replace component M16/6 (Throttle valve actuator).
