This procedure details how to bleed the ABS pump when replacing brake fluid.
This procedure is NOT necessary unless your ABS pump has gone completely dry.
For normal brake work including fluid replacement, hose replacement, pad replacement, etc. this procedure is NOT necessary.
Also, this procedure does not take the place of good ol' fashioned brake bleeding with one person operating the pedal while the other person opens the bleeder valves one by one and collects the discharged fluid.

There are certain test conditions that must be met before doing this procedure:

Vehicle must on a lift or safe jack stands with no wheels touching the ground

Ignition should be in the "On" position.


Procedure for Bleeding the ABS Brake Pump in many older VW Golf, GTI, Jetta, and Audi TT:

[Select]
[03 - ABS Brakes]
[Basic Settings - 04]

[Go!]

This will trigger the ABS pump to turn on for about 10 seconds. You should hear the fairly loud pump clicking during this time.

Click the [Done, Go Back] button and you're all set.
