Turbo charger solenoid failure

I have just received a call from my LR dealer, for a new
bulletin ( after I will post the exact code).
I have to go there for a turbo solenoid replacement and minor software updates.
Turbo solenoid failure could cause reduced performance evenif not signaled by computer with the "reduced performance" warning.
Infact, it' s some tome I notice my disco has a löss of performance when accelerating, particularly at about 2000/2500 rpm.
They say solenoid is responsible for the 2 turbos working together (sorry I don' t know how t translate exactly).

I'm wondering if my engine's current fluffyness for 1-2 seconds during manual upshift between 2000 & 3000 rpm is caused by this solenoid. Too far away from the dealers to warrant having it checked out just yet.

New software for KVM (Keyless Vehicle Module). There has been issues with the vehicle non-starting due to bad software.
