Is200t vacuum regulation valve

Genuine replacement at 2.5 years old After 4 visits to my lexus dealership In the end I googled the fault of loosing boost pressure when pulling away or onto a motorway slip the car would purge the power on and off My lexus dealership replaced the part under the warranty but now its faulty again just under 2yrs ago and only 4000 miles The fault this time is a loud buzzing from the valve and the boost fluctuates when you put the turbo up on the f sport screen -
Had a faulty valve replaced just less than 2 years ago Now the valve is faulty again and I have only travelled approx 4000 miles since the last unit was replaced
