Is it not caused by the exposed wire end of a wheel brush, couldn't see how the valves would bend that much

nope i have never used a wheel brush - with the car only being a week old all it needed was hot soapy water. I pushed both valve caps over and it lines up exactly where the scratches were. Not sure if bmw have changed the valves or soemthing they use for longer stem ones recently? Im kind of glad i have found this as now i can go and physically show the dealer. a aimple plastic cap would have resolved but the alloys are marked now. i will update tomorrow after going to BMW.
i cant believe im the only one that has had this.....there were a few other X5's being delivered when i got mine so maybe its a batch thing - or im ultra fussy!!
