Hi Marco, no but I hardly drive her ever...
At the APK (MoT) I always say it to the people at the station and only when they got an extra check then I have to remove it. But that hasnt happened yet.

You only can see the X when you are very close to the car and it can hardly be noticed when you drive it. Hope I never get police behind me when standing still at the traffic light....
And as you know I cant say its a 'crushed fly' because I usually mask up the front of the car when driving it..Hahaha.
