My 2007 Volvo S60R, had a Low Boost pressure issue, Everything was OK, no error codes, no Indicator lights, just low Boost.
it came out that the problem is with the TCV! The OEM part got probably stuck and didn't allow to create more boost.
The solution was easy. For that reason, I also bought and installed the ipd Boost Gauge which I like a Lot!
Hope this video will help someone who has a similar problem.

Enjoy.
