Looking for an Opel or Vauxhall ABS pump, ABS control module, ESP module or complete ABS hydraulic unit?
Opel and Vauxhall vehicles use ABS together with ESP/ESC (Electronic Stability Control) and traction control systems. A faulty ABS hydraulic pump or electronic control module can cause ABS, ESP and traction control warning lights, pump motor faults, brake pressure sensor problems and communication errors.
At AutoPulse247, we supply genuine used OEM Opel and Vauxhall ABS pumps, ABS control modules and complete ABS/ESP hydraulic units.
Our stock may include ABS pumps and modules for:
Opel / Vauxhall Astra, Corsa, Insignia, Zafira, Mokka, Meriva, Vectra, Signum, Adam, Agila, Antara, Cascada, Combo, Crossland, Grandland, Movano, Vivaro and other models.
This includes popular generations such as Astra H, Astra J, Astra K, Corsa D, Corsa E, Insignia A, Insignia B, Zafira B and Zafira C.
Different ABS units can be fitted to the same model and production year. Always compare the complete part numbers before purchasing.
A faulty ABS pump or ABS control module may cause:
The exact fault-code definition depends on the vehicle and ABS generation, but commonly encountered ABS/ESP codes include:
C0110 – ABS Pump Motor Circuit Malfunction
Can indicate a problem with the ABS pump motor, wiring, electrical supply or internal ABS hydraulic unit.
C0121 – ABS Valve Relay / Valve Circuit Fault
May indicate an electrical problem involving the ABS valve system, relay or internal hydraulic control unit.
C0131 – ABS / Brake Pressure Circuit Fault
Can be associated with brake pressure measurement, sensor circuitry or the ABS hydraulic unit depending on the system.
C0035 – Left Front Wheel Speed Sensor Circuit
Usually relates to a wheel speed sensor, wiring, connector or wheel bearing encoder rather than the ABS pump.
C0040 – Right Front Wheel Speed Sensor Circuit
Can indicate a wheel speed sensor or signal problem.
C0045 – Left Rear Wheel Speed Sensor Circuit
Typically associated with the rear wheel speed sensor, wiring or wheel bearing encoder.
C0050 – Right Rear Wheel Speed Sensor Circuit
Usually indicates a wheel speed sensor or associated electrical/signal problem.
C0550 – Electronic Control Unit / Internal Control Module Fault
An important code on some Opel/Vauxhall systems. It can indicate an internal ABS electronic control module malfunction.
C0561 – System Disabled / Invalid Data Received
Can occur when the ABS/ESP system receives incorrect information from another vehicle control module. It does not automatically mean the ABS unit itself is faulty.
U0121 – Lost Communication With ABS Control Module
Communication with the ABS/ESP control module has been lost. Possible causes include wiring, CAN Bus, power supply, ground or an internal control module failure.
U0415 – Invalid Data Received From ABS Control Module
Another vehicle module has received invalid information from the ABS/ESP control module.
C0110 is an important fault when diagnosing certain Opel/Vauxhall ABS systems.
Possible symptoms include:
Possible causes include the ABS pump motor, electrical supply, wiring, connector or internal ABS hydraulic unit.
The pump should be properly diagnosed before replacing the complete assembly.
C0550 can be particularly relevant when an internal ABS electronic control module problem is suspected.
Depending on the ABS system, symptoms can include:
Power supply, grounds, connectors and CAN communication should still be checked before replacing the control module.
Not necessarily.
Opel and Vauxhall ABS/ESP warnings can also be caused by:
If these external causes have been eliminated and diagnostics confirm an internal ABS module, pump motor, hydraulic unit or integrated sensor failure, repair or replacement may be required.
The ABS assembly normally consists of:
ABS Hydraulic Block – regulates hydraulic brake pressure at individual wheels.
ABS Pump / Motor – generates hydraulic pressure when required by the ABS/ESP system.
ABS Electronic Control Module – processes sensor information and controls ABS, ESP and traction control functions.
Depending on the fault, the electronic module, hydraulic section or complete ABS pump and control module assembly may need replacing.
Do not choose an ABS unit based only on:
Model + engine + production year.
Opel/Vauxhall vehicles can use several ABS versions within the same model range.
The original unit may contain:
Always compare all available numbers on your original ABS unit.
Two ABS pumps can look identical externally while having different electronics, software, coding or hydraulic configurations.
We regularly supply ABS units for popular models including:
Vauxhall / Opel Astra H, Astra J and Astra K
Vauxhall / Opel Corsa D and Corsa E
Vauxhall / Opel Insignia A and Insignia B
These vehicles can have multiple ABS variants depending on the engine, gearbox, production date, braking system and vehicle specification.
Matching the complete OEM and manufacturer numbers is therefore essential.
ABS pumps and modules are also available for vehicles such as:
Opel / Vauxhall Zafira
Opel / Vauxhall Mokka
Opel / Vauxhall Vivaro
Opel / Vauxhall Movano
Opel / Vauxhall Combo
Commercial vehicles in particular may have different ABS configurations according to wheelbase, weight class, drivetrain and production year.
A replacement ABS module may require:
Some modules may require programming to the vehicle before normal operation is restored.
AutoPulse247 supplies genuine used OEM Opel and Vauxhall ABS pumps, ABS control modules and complete ABS/ESP hydraulic units.
Search our store using your:
Opel OEM number, Vauxhall number, GM part number, Bosch number, ATE number, Continental number, ABS pump number or control module number.
Matching the complete numbers from your original unit is the safest way to identify the correct replacement.
Send us:
Your VIN + ABS/ESP fault codes + complete ABS part number + a clear photograph of the label on your original ABS pump/module.
We can use these details to help identify a suitable replacement from our available stock.
Important: ABS and ESP fault codes are provided for general diagnostic information. Exact definitions can vary between Opel/Vauxhall models and ABS generations. A fault code alone does not confirm that the ABS pump or control module is defective. Proper diagnostic testing should always be performed before replacing braking-system components.
