I really just need to get more info than “low boost” so would I need a subscription?

Yeah the subscription sucks, but once the adaptions are done you don’t really need it.

Does VCDS have an app integration?

I replaced the diverter valve, same problem.

The charge pipe was disconnected at first after I replace the turbo - metal clip wasn’t locked - but still low boost after that was fixed.

Had my usual mechanic do a smoke test and no leaks.

And the turbo had a brand new boost control valve and diverter valve.

And the other weird thing is my old turbo seemed to be fine, with no play in the wastegate or friction.
