Err. I take that back, metered air is missing, so pressure side, post turbo. Pressure test either way.

Brake servo pipes split, recommend you check them from inlet all the way back to the servo

I checked the vac line to the brake booster, the silly pump and the other vac lines i have removed!
I got a vac line from the intake manifold over a check valve directly to the break booster

Is it a wideband car? If so, post logs. If not, get a wideband.

Which values could be helpful to find out more about the problem?

Sorry guys for doubleposting, but could the rear o2 removing cause the problem with the negative fuel trim?

no, if you coded them out correctly.
and even if you didn't, I am unsure how you'd end up with a double digit trim.

it is my understanding that if you hear air rush when you pump the brakes along with idle changes and vacuum changes, the brake booster itself/lines/checkvalves has a leak. The brake booster should hold a vacuum during its test. I guess you could plug up the port on the intake manifold used for the brake booster and see if trims change. It might be hard to stop though.
