Mercedes-Benz W176 (A-Class) ABS Pump & Module | Genuine Replacement

Description

The ABS (Anti-lock Braking System) pump—often coupled with the Electronic Stability Program (ESP) module—is the brain and muscle of your W176’s safety system. If you are seeing persistent “ABS/ESP Inoperative” warnings, “Traction Control” errors, or if you feel the pedal “pulsing” when it shouldn’t, the pump or its electronic control unit (ECU) may be malfunctioning.

Because these units are VIN-coded to your vehicle’s central gateway, replacing them with a workshop-vetted original component is the most reliable way to restore factory-perfect braking safety.

• System Integrity: Our units are tested for valve-block responsiveness and electronic communication with the vehicle’s CAN bus system.

• Safety Critical: Each unit is verified to ensure it can successfully modulate brake pressure to each wheel independently during an emergency braking event.

• Condition: Premium workshop-vetted original component; inspected for electronic fault-code integrity and clean, corrosion-free hydraulic ports.

Signs Your ABS Pump/Module is Failing:

• Dashboard Warning Lights: Persistent “ABS,” “ESP,” and “Run-Flat Indicator” warnings on your instrument cluster.

• Lack of ABS Function: The brakes lock up during hard braking because the pump is not activating to modulate pressure.

• Communication Errors: Diagnostic scanners return “ECU Communication Fault” or “ABS Pump Motor Circuit” error codes.

• Speed Sensor Issues: Sometimes, an ABS pump error is triggered by a failure in one of the wheel-speed sensor circuits within the module itself.

Workshop Pro-Tip: Do not assume the pump is dead immediately. The W176 ABS system is highly sensitive to voltage. A weak battery or a corroded ground strap can cause “ghost” ABS errors. Always check your battery voltage and system fuses before committing to a replacement. Furthermore, if you do replace the unit, you must perform an “ABS Bleed” procedure using a diagnostic tool to remove air from the valve block, and the new module may require “SCN Coding” to your vehicle’s VIN to function correctly.

Key Features:

• Vehicle-Specific: Engineered to match the exact braking requirements and chassis configuration of the W176 A-Class.

• System Ready: Tested for electronic compatibility with your car’s existing safety network.

• Quality Assured: Vetted for hydraulic performance and internal solenoid health.
