D4 2011. GRAPH.Secondary turbocharger, shut off valve issue?
Hello everyone.
I have powerstep - turbo lag on 2500rpm on My D4 2011 tdv6 3.0. Graph shows manifold pressure on full throttle on manual 4 gear, from 1300 to 4000 rpm. There is no errors on dash or diagnostic but lag of power is big.
Any ideas?
Thanks a lot.

That looks very much like a sticking actuator, the dip in the middle is the ECM trying the 'unstick' procedure to measure current draw and response.
