    I had problem with fuel starvation above 3000 rpm, but not as severe as you describe. The only error I had was "Fuel range exceeded", Intermittent.

    My assumption was the sensor but I replaced both the valve and the pressure sensor while the intake manifold removed. The fault disappeared.

    It does sound like the N276 is passing, if it has an intermittent problem and is being lifted at 120bar, it would not surprise me if this has damaged the seat of the valve if this has happened repeatedly. I wouldn't expect the valve to be passing when it is showing as shut, but I don't know for sure. May be worth trying a 2nd hand unit instead of new to see if this helps without spending the

    I would recommend you to replace both units with new ones! You don't want to dismantle the intake manifold a second time.
