The BMW brake booster vacuum line / hose (OEM 7623234) is a used genuine part originally removed from an i3 or i3s. This vacuum hose routes to the brake booster to supply the vacuum needed for power assist. A cracked or leaking line can cause a hard brake pedal or reduced braking assist. It fits both the range-extender (0.6L) and pure EV drivetrains.
