Clutch Mechanism, Bleeding
Special Tools And Workshop Equipment Required
- Brake Charger/Bleeder Unit :VAS5234 or
- Brake Charger/Bleeder Unit :VAG1869
The system must be bled after working on the hydraulic clutch mechanism.
Make sure no brake fluid gets on the transmission when performing the following work.
It is not necessary to pre-fill the system.
Before bleeding, fill the brake fluid reservoir to the "Max" marking with brake fluid.
The clutch pedal is in the neutral position and is not pressed.
Brake fluid: allocation.
-- Remove the complete air filter housing if the bleeder valve -arrow- is not accessible. Refer to AIR FILTER (CVCA, CUUA, CUUB, DELA, DEBA, DEJA, DGMA) or AIR FILTER (CNLA, CRJA) , AIR FILTER (CZCA, CZDA, CZTA) , AIR FILTER (CBPA, CKJA) and AIR FILTER (CPLA, CPPA, CPKA, CPRA) .
-- Connect the Brake Charger/Bleeder Unit :VAS5234 or :VAG1869 .
It is necessary to use the Bleeder Hose (670 mm) : VAG1238/B3 to bleed.
-- Connect the bleed hose to the brake bleeder unit collector bottle.
-- Connect bleeder hose -A- to bleeder -arrow-.
-- Apply 2 bar (29 psi) pressure to the system.
-- Open the bleed valve.
-- Move the clutch pedal manually 15 to 20 time very quickly from stop to stop.
-- Close the bleeder valve and switch the Brake Charger/Bleeder Unit off.
- Bleeder valve with hex fitting: Tightening specification, 4.5 Nm
- Bleeder valve flattened on both sides: seal off all the way
-- After completing the bleeding procedure, and the pressure has dropped from 2 bar (29 psi), operate the clutch pedal an additional 10 times by foot.
-- If removed, install the complete air filter housing. Refer to AIR FILTER (CVCA, CUUA, CUUB, DELA, DEBA, DEJA, DGMA) or AIR FILTER (CNLA, CRJA) , AIR FILTER (CZCA, CZDA, CZTA) , AIR FILTER (CBPA, CKJA) and AIR FILTER (CPLA, CPPA, CPKA, CPRA) .
