Have a slight constant vibration above about 10mph + on the left hand side, I can feel it through the steering wheel on the left hand side and the floor, had top mounts,wheel balanced and new tyres recently so they are ruled out… anyone else had something similar or know the cause.(BMW m140i 2017)

Suspension bushing? Tie rod for example.

Hello in West Yorkshire. I grew up there a long time ago. Don't rule out a bent wheel. Additionally, even though it's new, the left front tire could still be bad from a uniformity point of view (variation in radial stiffness - not static or dynamic balance). Switch the left front tire and wheel with the right front tire and wheel and see if the vibration follows the wheel and tire assembly. It's also possible a wheel weight might've been thrown off.

Hello from west yorkshire, thanks for the information really helpful, i am going to swap the wheels around and see if it continues, how would i determine if its a bent wheel or the tyre? if its the tyre is a new tyre needed... they where only put on a couple of months ago, and i am guessing if its somehow a bent wheel, either a repair or a new one?
