If you search for a link 'Where to start on a 930", that is me trying to sort my way thru these issues. Goran gives a good link there how to remove plenum - I can do it with eyes shut now (50 times at least) - but need to make sure you have the right hoses disconnected etc.
To strip down to intake manifold (removing plenum) really is no more than half hour.
Gives you plenty of working room. The trick then is to pressurise system to some useful degree to check the lower seals. This of course does not test integrity of plenum/intercooler seals - but easy working room to work on anything else.
If you want to test all seals - then you need to work something like my pic. But sounds like your leak is at lower end anyway. So, easier to remove all top stuff. Need large bung to block intake hole for pressure - about 90mm dia from memory.
