Re: bleed valve yes or no
Don't know anything about these personally, but the general view is it''ll live forever if you don't tinker with it, or about 5 minutes if you do.
2002 HDi 2.2 Exec Estate, (2008-12) (wonderful)
2003 HDi 2.2 6-speed Exec Estate (2012-19) (also a gem)
2009 Citroen C5 2.0 HDi VTR+ Estate (godawful heap)
2008 BMW E91 330i touring (great fun - murdered by a reversing SUV)
2007 BMW E91 325i touring (slower smoother quieter)

bleed valves ....
Hate them ! there unreliable, cause more problems than there worth, and self adjust over time as the spring weakens, cause the turbo to over work.
If you cant warrant buying a proper electronic boost controller, then get a grainger type valve.. much more reliable, and not a lot more money than a standard bleed valve.
I cant comment on how a 406 responds to a bleed valve in regards to over boost or safe levels, all i can tell you is my experience from years of tuning highly modified cars the Bleed Valves are sh*t !
Either way providing you can get to the vacumm line that comes off the actuator, there very simple to fit
