I don’t think it’s the trim because if you notice on the top right of the MCU, you have a gap as well. My guess is you didn’t screw in or snap in a piece completely.
Hmm I am going to pop that right hand side up again and try to align the clips from center of dash outward again to see if it improves but it does not seem to wanna go down any further no matter how much i beat on the top of the dash. Inserting another close up pic anyways. There is no actual visible gap between the aluminum liner bit and the top(maybe its not as flush as it could be though? But the CF and to rhe right at the air vent can def se a small gap, maybe a clip close to that region never snapped in well and is now preventing it to hold as flush as it should.
