NOTE
Bleeding the brake system on vehicles with ABS is the same as for vehicles with a conventional brake system, with the exception of using function 04 to bleed systems that have been completely empty.

  1. On vehicles with a brake pressure regulator, move the regulator lever when bleeding rear brakes.
  2.  
  3. Connect brake filling and bleeding unit.
  4.  
  5. Open bleeder valves in specified sequence and bleed brake calipers in the following sequence:
    1. 1 - Right rear caliper
    2.  
    3. 2 - Left rear caliper
    4.  
    5. 3 - Right front caliper
    6.  
    7. 4 - Left front caliper
    8.

  7. On vehicles with ABS or ABS/EDL, test drive the vehicle and perform at least one brake application sufficient to engage ABS regulation.

NOTE
Please note the following important points about vehicles with ABS/EDL, ABS/EDL/ASR and ABS/EDL/ASR/ESP:



When at least one chamber in the brake fluid reservoir is completely empty (e.g. leaks in braking system) the hydraulic unit must be bled with scan tool VAG 1551 in function "basic setting".
 
Brakes must be bled in the proper sequence
 
Then the hydraulic unit must be bled with scan tool VAG 1551 in function "basic setting".
 
After bleeding the brake system, perform a zero compensation of the brake pressure sender.
 
Once the bleeding sequence is completed. Carry out a test drive and perform at least one ABS application when doing this.
 


WARNING
Make sure that a filling pressure of 1 bar (14.5 psi) is not exceeded, when filling brake fluid using brake filler and bleeder unit VAS 5234. The brake fluid pressure must be reduced to 1 bar (14.5 psi) on brake filler and bleeder unit VAS 5234. Refer to the equipment operating instructions


WARNING
Brake fluid is poisonous. Brake fluid must not come into contact with paintwork as it is very corrosive. Brake fluid is hygroscopic, which means it absorbs moisture from the ambient air and should always be stored in air tight containers. Rinse off any spilled brake fluid using plenty of water.

  1. Connect brake filler and bleeder unit VAS 5234.
  2.  
  3. Open bleeder screws in the following sequence and bleed brake caliper/wheel cylinder:
    1. 1 - Left front brake caliper
    2.  
    3. 2 - Right front brake caliper
    4.  
    5. 3 - Left rear wheel cylinder/brake caliper
    6.  
    7. 4 - Right rear wheel cylinder/brake caliper
    8.  

  4.  
  5. With hose still connected, leave the respective bleeder screw open until brake fluid is free from air bubbles out of the bleeder screw.
  6.  
  7. A test drive must be carried out after bleeding brakes. When doing this an ABS application must be performed at least once!
  8.  
  9. Pre-bleed the brake system when at least one chamber in the brake fluid reservoir is completely empty (e.g. leaks in braking system). Pre-bleeding sequence
    1. 1 - Bleed left front and right front brake calipers simultaneously
    2.  
    3. 2 - Bleed left rear and right rear brake calipers simultaneously
    4.  
    5. With hose still connected, leave the respective bleeder screw open until brake fluid is free from air bubbles flows out of the bleeder screw.
