Boost cut issue, diagnosis help needed

Jun 3, 2020
Preston, UK
Hey everyone,
I have a MK1 Leon cupra (180), and when I put my foot all the way to the floor and hit about 3.5K rpm, the boost cuts out and the engine light comes on for a minute then clears, but if I'm more careful then boost holds all the way through the rev range. Feels like maybe a BOV or bad N75 but I don't know anything about the 1.8t and want some opinions before I take it to a garage as this is my daily car. Cheers!

When it cuts out is there a orange light flashing on the dash?
Also have you done anything to the car prior to this happening?
