What this part does
The ABS Control Module, referred to as the DSC module by BMW, manages the anti-lock braking and dynamic stability control systems. Mounted directly to the hydraulic pump block in the engine compartment, it continuously monitors data from the wheel speed sensors, steering angle sensor, and yaw rate sensors. It modulates brake fluid pressure to individual calipers to prevent wheel lockup during hard braking and corrects oversteer or understeer in low-traction situations. A failure in this unit typically disables the ABS, traction control, and stability control systems, triggering multiple warning lights on the instrument cluster.

Before you order
This BMW DSC module requires professional coding and initialization to the vehicle it is being installed into. Because it stores the VIN and vehicle-specific calibration data, simply plugging it in will result in system faults; programming via ISTA or a high-level bidirectional scan tool is mandatory.
Installation requires opening the hydraulic braking system. A pressurized brake fluid bleed, followed by an electronic ABS pump automated bleed procedure, must be performed to remove trapped air from the internal valve block.
Match the part number 3451688293301 exactly to the sticker on your original unit. Modules differ significantly depending on whether the vehicle is rear-wheel drive or equipped with the xDrive all-wheel-drive system.
