If i dont own a boost gauge, how can i diagnose if i have a vacuum/boost leak or a broken wastegate?

Will vag-com detect any of these things? Does the dealer have any tests it can aside from opening up the engine and looking?

Thanks.

the third column is requested, 4th is actual. You want these numbers to be pretty close to each other. (within 20-30 mbars i'd say) - if they aren't, you might have a leak somewhere.

Sorry, Im new at this and do not currently own a vag-com, although i will in the near future.

I suppose my real question is can i assess the condition of my turbo/vacuum hoses and whether it is running properly simply by pluging in a vag-com and running a test?

Thanks again.

My local shop didn't find anything wrong by using the VAG, but they certainly found a torn hose on visual inspection.
