Work Procedure
-- Remove the engine cover. Refer to ENGINE COVER, REMOVING AND INSTALLING .
-- Connect Hand Vacuum Pump: VAS6213 to vacuum diaphragm -arrow-.
-- Set the slide ring -1- on Hand Vacuum Pump: VAS6213 to position -B- for "vacuum".
The pressure must not exceed 750 mbar (11 psi) If the pressure is exceeded, the vacuum diaphragm can be damaged.
-- Operate : VAS6213 several times and observe rods.
The linkage -A- must move approximately 300 mbar (4.4 psi) and be at approximately 700 mbar (11 psi) at end position.
The linkage stroke is approximately 10 mm.
If pressure cannot be raised using the : VAS6213 or pressure drops immediately, check the : VAS6213 and connecting hoses for leaks. If no fault is detected: replace the vacuum diaphragm. Refer to TURBOCHARGER VACUUM DIAPHRAGM, REPLACING, 1.8L ENGINE ONLY .
