1.1.3. 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).
