Abs pump and brake bleed using vcds?

[CHRISTOPHÉ]

Hi I know it can be done and I've found how to's for other cars but I can't seem to get to the procedure on mine, I can run the output tests and found the drop down for bleeding but I'm unsure how to start it?
Any help appreciated. Thanks.

This is not helpful, but I was going to recently do this and asked my dealer how to do it. They informed me that when they do a brake bleed it actually bleeds thru the abs module. This is what they told me. I am forced to believe them even after hearing the opposite elsewhere.

IIRC it's in measuring blocks and you switch to basic settings and the pump runs for a few seconds.

If you still can't figure it out I'll revisit it tomorrow and give you better info.

Here's how I did it with VAGS....should be very similar with VCDS.

Example #2:
I want to bleed my ABS/ESP pump (you can find easy to follow instructions on ross-tech.com for this but let's do it the hard way!)

1) find you part#/label file
2) find "bleed" in file
3) you'll see this:
B002,0,Brake System Bleeding
B002,1,Status, ,
B002,2, , ,
B002,3, , ,
B002,4, , ,
4) Bleeding is in "Basic Seetings" (thus the number is prefixed with "B"), in block 002.
5) Fire up VAg401, ABS, Log in (find log in code on ross-tech.com or in workshop manual, C5 ABS takes "40168" code though!), block 002
6) press ENTER and the pump will bleed
7) Repeat as many times as needed.

I hope this is helpful.

Ah I tried the measuring block 002 but hadn't logged in as I was pushed for time and didn't want to re calibrate the steering angle sensor.
I'll hopefully try this over the weekend just waiting on a few more bits to arrive.
Thanks.

The procedure is to bleed all the brakes with a pressure bleeder at 29 psi as follows.

RR, LR, RF, LF

After bleeding the Left Front (last one) you leave the bleeder open and run the procedure to bleed the ABS pump via VCDS.

If you do not have a pressure bleeder I would not bleed the ABS pump. I would only bleed the calipers.
