Salut à tous,
Petit tuto pour la purge du circuit interne abs, quand on le remplace lui ou que l'on remplace le liquide de frein car une purge simple au 4 étriers ne suffit pas pour extraire le liquide du bloc abs.
Dans mon cas remplacement.
[Select]
[03 - ABS Brakes]
[Basic Settings - 04]
Group 001
[Go!]
Once you hit GO! the screen says to depress pedal and hold
You have to press the pedal HARD. Seriously, pound the pedal like you're about to drive over a cliff. Remember to hold the pedal down!
The pedal will drop, the pump runs briefly, then the pedal comes back up.
Take your foot off the pedal.
I think it wants you to click on OK at this point.
The screen says something like FR/FL bleed screw OPEN.
Open both front bleed screws. Obviously, on each bleed screw you'll have some tubing going from the bleeder into a catch jar.
Click on OK (or DONE or something like that).
Pump runs for 10 seconds, pushing fluid out of the bleeders into your catch jars.
Screen says something like: Depr. pedal 10X; bleed screw CLOSED
Depress pedal firmly 10 times, then close both bleed screws.
Click OK.
You'll get sent back to the depress pedal and hold screen and repeat the cycle. It goes on for like 10 or 15 cycles. I never got a finished message, I just did it until the screen said N/A.
It is easier with two people. One in the car pressing the pedal and working Vag-Com, the other outside opening and closing bleeders and making sure the master cylinder doesn't run dry (very important!).
If you're doing this solo, put the laptop on the driver's side roof so you can access it easier. It's also a great workout as you run in and out and around the car.
After the ABS pump is bled, you can then bleed the rest of the system as normal.

Pour résumer (traduit avec Google) une fois appuyer sur Go :
VAGCOM demande via une fenêtre: "depress pedal and hold" = donc il faut appuyer fort sur la pedale et la laisser bouger toute seule tout en continuant d'appuyer
ensuite VAG COM envoie un "OK" a comfirmer = cliquer sur OK et enlever le pied de la pédale
VAGCOM envoie une nouvelle fenetre disant "FR/FL bleed screw OPEN." = Ouvrir les vis de purge avant et cliquer sur OK dans la fenetre = ça pousse le liquide tout seul pendant 10 secondes
VAGCOM envoie un nouvelle fenetre disant "Depr. pedal 10X; bleed screw CLOSED" = Appuyer 10 x sur la pédale de frein et ensuite aller fermer les 2 vis de purge.
Ensuite on peut faire une purge sous pression traditionnelle sur les 4 roues par sécurité.
Voili
A+
