ABS hydraulic unit removal A4 B7 2.0 TDI, year 2006

Hello everyone,

I would like to bleed the ABS block, but I cannot find the corresponding function under "03 Brake Electronics / 04 Basic Settings". Could it be that on the Audi A4, the pump can only be controlled via the actuator diagnosis? Does that mean that one can simply bleed the pump without specific instructions while it is in operation?

Thank you in advance for your help!

Greetings
Tobi
