Have you tried working the mark 3,what a load of shite it is,after all the years they bring out noisy piece of shite, I know u can mute it but it is useless, only problem with the mark 1 was the wheel were always loosen,the mark 3 is like a little ambulance noise and lights,had mark 3 but sold it,know a lot of people don't like mark 3,so when is mark 4 coming out hopefully mark 1 with better whee.l
