Hi That's what thought. Although the guy I spoke to from online turbo refurb place sounded like he knew what he was talking about (and he did say a lot of things that I knew to be correct) the fact that he said both turbos were VVT made me think twice. He was very keen to tell me fitting the shut off valve would not solve my issue and only a complete refurb of my existing turbo would. this is in contradiction of my local independent LR specialist who had my car for a week, did extensive testing a diagnostics (including testing the variable veins on the primary turbo) had told me I don't need a complete new turbo but only the shut off valve. Also the online guy went into great detail on how the VVT turbo worked both electrically and mechanically but when I said it was secondary turbo I was having problem with he still wanted me to remove entire turbo for him to refurb.

Hi thanks for getting back to me. My symptoms were a restricted performance warning every time i took car above 2800RPM. This is when secondary turbo should kick in but as the valve is faulty it was triggering a fault resulting in restricted performance mode. This was confirmed by a reputable independent LR specialist. The first garage I went to wanted £8100 to replace both turbos needless to say I wanted a second opinion and they told me after much investigation it was the "Turbine Valve" on the secondary turbo. This was confirmed in March 22 and as of today I am still waiting for them to get in touch when they receive the new valve. I contacted LR myself re the valve and they said I could order (and pay) for one but could not give me a delivery date.
