ABS Pump Bleed Cycle

[Tallpaul]

Need to check the operation of the ABS pump on my A3 1.8T.

Can the 10 second ABS pump cycle that VAG-COM initiates be performed with the wheels on the ground, bleed valve shut ie car as normal?

Might help if you told us what year A3 and the specifics of the control module. These cars were made for a number of years and the ABS changed over time.

How does the year of the car affect whether it's safe/possible to run the pump when you're not actually bleeding it?

Anyway:

Control Module Part Number: 1J0 907 379 E
Component and/or Version: ABS/EDS 20 IE CAN 0001
Software Coding: 13504
Work Shop Code: WSC 06435

It's a non-dbw 1998 Audi A3 1.8T Sport.

Cheers.

The year of the car affects it because they have different control modules / ABS systems and I want to look at the correct documentation.

You've got a Teves 20, almost identical to the one I had in my 1997 Golf VR6. I don't think there's any harm in starting the Output Test sequence or the Bleeding Sequence (Basic Settings Group 001) and then aborting it after you've verified that the pump runs. I've done both in the distant past on the VR6 (which I sold in 2002) but neither of these is an "approved" procedure in the repair manual so I'm not going to give you any iron-clad guarantees.
