This stems from another post I have, in thinking about the replies however I am boiling it down to one, perhaps simpler, question.

 

Why is my requested boost so high at idle?

 

Requested boost 1091.4 mbar

Actual boost 999.6 mbar.

 

I now understand that both figures should be very close and also be close to atmospheric.

 

Obviously atmospheric will vary with conditions and height - I am close to sea level

New MAF Valve

New MAP Valve

New Turbo

New Solenoid valve block

New EGR valve

Vacuum lines checked with vacuum pump

 

 

Thanks

So that's 1 bar, sounds about right to me.

^{Yes, not perhaps massively over atmospheric but still a difference of 91.8 mbar between actual and specified.}

^{I have been told that cars which are fine show a very close match between actual and specified boost.}

91.8mbar (0.091bar) is tiny and just fine.
