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: Perform mechanical inspection of component M16/6 (Throttle valve actuator).
Test 1.2: Note : Control unit programming must be performed on control unit variants VC6 to VC8.
Test 1.3: Check component M16/6 (Throttle valve actuator) using actual value.
Test 1.4: Check component M16/6m1 (Actuator motor) by means of actuation.
1.1. 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).
1.2. Note : Control unit programming must be performed on control unit variants VC6 to VC8.
1.2. No further information available.
1.3. Check component M16/6 (Throttle valve actuator) using actual value.
Warning!Communication with ECU required.
1.4. 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°, unmetered air may be present.
Status of relevant actual value:
- Throttle valve angle:Warning! Communication with ECU required.

Temperature of gear oil is too high.
Possible cause:
- Temperature of gear oil is too high.
Affected functions:
- Automatic transmission Function
-------------------------------------------------
Test 1: Remedial action if transmission oil temperature is too high
1. Remedial action if transmission oil temperature is too high
Operation number of operation texts and work units or standard texts and flat rates:27-0641 Error response:- Control unit Y3/8n4 (Fully integrated
transmission control (VGS) control unit) initiates a reduction of the engine torque in relation to the measured transmission oil temperature.- The
reduction of the engine torque necessarily produces a power loss in the engine.POSSIBLE CAUSES
- This fault code may have resulted from the transmission having previously gone into emergency mode, or from stored fault code 2759.
REMEDY
- If fault codes are present, process these.
- Check transmission oil cooling for proper operation and for leakage.
- Perform condition check of the transmission oil.(Continue with button "F6")
