As per factory manual.

1. Loosen and remove control line to WG.
2. Run engine at idle speed. There must be noticable vacuum in control line. With increasing engine speed, vacuum changes to pressure (charging pressure).
3. Insert a plug in disconnected control line, so that engine will not stall while checking WG operation.
4. Carefully blow compressed air into control line opening of WG. Listen for sound of WG opening.

Caution
Do not use more than 1.5 bar (21 psi) air pressure.

Check bypass line warms up (cold engine).
