didn't think this warranted the tech but here goes

[[IX]]

With A/C on
Rough idle
12 Hg of vac.
Speratic boost
All vent options work

With A/C off
20 Hg of vac
Steady idle
Consistant boost spikes at 22 and holds 12-13 lbs

Where could the leak be? I sprayed every connection w/ soapy water and no
results.

TIA

Since things are normal with your A/C off, I don't think you would have a boost leak. You might want to re-align your throttle body could be a start.

I was thinking more of a vacuum leak somewhere

This is an update question.

Does anybody know where a HVAC vacuum leak would be, that disappears when I push the ECON button?

Honestly, i don't think there are many vac. systems in our B6's. Thats why I'm saying do a throttle body alignment and see if that works. B/C when you turn your A/C on, your DBW throttle body starts listening to your HVAC b/c there's an additional load on your engine now.

[[IX]]

Maybe I did the Throttle Body Alignment wrong I followed this as posted above

Procedure for performing a Throttle Body Alignment on DBW Cars using KWP-2089:
(Check to see if the engine speaks KWP- 2089 by looking in the top left of the Open Controller Screen Some examples of KWP-2089 engine controllers are 2002+ Audi A4, 2002+ VW Passat, and Touareg)

Turn the key on but do not start the car.

[Select]
[01 - Engine]
[Basic Settings - 04]
Group 060
[Go!]
It should say "Basic Settings: OFF" on the top of your screen.
Click [ON/OFF/Next] to turn on Basic Settings.
It should now say "Basic Settings: ON" on the top of your screen.
Once you do this you will see the top right display say ADP RUN. The TB adaptation is being done as soon as you switched basic settings on. You will see the values change and hear the TB cycle for the first few seconds then it will stop. Leave it in Basic Settings for about 30 seconds.
Click [ON/OFF/Next] to turn off Basic Settings.
It should now say "Basic Settings: OFF" on the top of your screen
Click the [Done, Go Back] button and you're all set.

Be sure not to touch the accelerator and make sure the engine is NOT running when

Your HVAC system doesnt use engine vacuum. Its all electronic. Pushing the "ECON" button will not allow the a/c compressor to engage. IS your A/C cold?

yes

Problem solved. One clamp loose on the oulet side of the FMIC.
