I was having this problem too. I just bought my ST a little over a week ago and it bothered me that my Dad's ST speedometer always centers, but mine seemed stuck left. I played with the settings today until I found the combination. With the engine running, go into Driver Assistance Settings. Go to Pre-Collision Assist and then turn off Distance indication. It will only stay centered until I turn cruise control on, but so long as cruise is off, speedometer is centered with Distance indication off. I'll play with it more tomorrow, but it has worked for me so far.
