Exclamation boost solenoid

I was recently driving on the freeway and got the drive train malfunction message. i got home and plugged in and the code says i need to change the boost solenoids. Can anyone shed some light on where the boost solenoid is on the 2013 M5?

Functional description
The blow-off valve prevents ”pumping” against the closed throttle valve, thus improving engine acoustics. In addition, the blow-off valve protects the exhaust turbocharger against damage. Another effect: the exhaust turbocharger reacts quickly when the throttle valve is opened again. Without the blow-off valve, the exhaust turbocharger would work against the ram pressure of the closed throttle valve and become slower. On opening the throttle valve, the exhaust turbocharger would react with a delay.
The engine control activates the blow-off valve. The blow-off valve has the positions: open and closed (no intermediate positions).
