Hi Rab,
Turbo was professionally overhaul and inlet manifold cleaned few years ago without significant increase of power.
I finally had the chance today to do VCDS recordings (my laptop have no battery) : no boost ! 0.2 bar instead of 1 bar.
And now always come back P1556 (before randomly after too much city use).
What can prevent normal boost when turbo/VNT/inlet OK ? There is no air leak noise.
I swear I have not such loss of power when I unplug the VNT on my other car (LUPO 3L) !
Thank you
