Bosch BMW F10 DSC ABS Pump 34516799515 - Used Original Parts

Quick Answer

This is the right fix when the F10 shows DSC and ABS warnings and diagnosis points to the hydraulic unit or pump motor itself, not to a wheel speed sensor, wiring or the brake fluid level. A tested Genuine used unit makes sense in Malaysia because the new dealer part is costly, and the original Bosch hardware in a donor car was built to the same tolerances as the one it replaces. Confirm that the fault is inside the unit before buying, because a pump swap will not cure a sensor or harness problem.

Diagnosis and Common Symptoms

The DSC hydraulic unit on the F10 combines the pump motor, solenoid valves and control module in one assembly. When it ages, the car usually warns you before braking is affected. The base hydraulic brake still works, but the safety systems that depend on the pump drop out.

Typical dashboard and driving symptoms:

• DSC warning light and yellow ABS light on together, often after a cold start or a short drive.
• Red brake warning with a "DSC failure" or ABS check message in the iDrive or cluster.
• Loss of related functions: Dynamic Cruise Control, Auto Hold, hill start assist and brake-related electronic parking brake functions may become unavailable.
• Pump motor running with no braking demand, or a buzzing or grinding noise from the engine bay near the brake booster.
• ABS not intervening on a slippery surface, or a pulsing, unpredictable pedal feel.
• Faults that appear or disappear with temperature or battery voltage.

Fault memory (read with ISTA or a BMW-capable scanner): Typical entries in the DSC module include pump motor circuit or plausibility faults, valve relay faults, internal control unit faults, and pressure sensor signal faults. Exact code numbers differ by software version, so read the full description and freeze-frame data rather than relying on the number alone.

Rule out these first:

• Low brake fluid or a failing brake light switch.
• Weak battery or low voltage, which causes false DSC errors on the F10.
• Wheel speed sensor or tone ring faults, which are far more common than a pump failure.
• Corroded connector pins or moisture at the DSC module plug.
• Brake fluid leaking into the module connector, which damages the electronics.

If the pump motor or valve block faults persist after these checks, the hydraulic unit is the cause and replacement is justified.

Introduction

This is a Genuine used Bosch DSC ABS pump unit removed from a BMW F10 and tested before listing. We handle F10 brake electronics in the workshop regularly, so we only sell units that have passed a functional check and show no signs of fluid ingress or connector damage. A Genuine used unit keeps the original Bosch internals and fit, without the dealer-new price. Photos of the actual unit are available on request.

Product Details

• Brand: Bosch (BMW Genuine)
• Model Compatibility: BMW F10 5 Series (verify by part number 34516799515 and VIN before ordering)
• Part Name: DSC ABS Pump / Hydraulic Unit with Control Module
• Condition: Genuine Used (Tested Working)
• Notes: Match the part number on the unit label exactly. After installation the DSC module normally needs to be coded to the vehicle with ISTA, and the brake system must be bled using the ISTA ABS/DSC service function. Check the brake lines and connector for corrosion or leaks before fitting, and clean the connector pins.
