Bentley manual and vag com
Trying to check my electric vacuum pump but the bentley manual is different from the vag com program. Sort of confusing. Can someone clarify the procedure for checking the vacuum pump? Thanks in advance.

is this what you are talking about?
P1479 17887
Brake vacuum system
Mechanical malfunction
- Perform a short trip in Engine Control Module (ECM) (basic setting; display group 8 with ignition on and selector lever in "P" or "N")
- Check hose setup to pump or from the pump to brake booster
- Perform output Diagnostic Test Mode (DTM) in Engine Control Module (ECM) to check whether the vacuum pump runs or is activated

Yes, but I got confused with the vag com software...
it seemed different from what the manual. Got to the basic setting, display group 8. Then I got lost.
What exactly does that fault code mean.

I dont think you can change anything on basic settings for grp 8
displays data only.
If you turn the key off and back on, you'll see it retest the vacuum pump
(at least it tries on mine) and then mine shows "failed".
There is another option you can use to cycle thru all the switches and motors. Shows things like "grounding N75" etc and you can hear the relay click. When I get to the vacuum pump option, (as you can see a couple posts down) it doesn't seem to work for me. But I'm not getting any terminal voltages at the device,either.
I don't know what to do about this problem.
I've got another issue with either MAF or broken vac line someplace I think, I cant find it for anything...
