Opel ABS Pumps and ABS Control Units

Opel ABS Pump – Complete Hydraulic Unit with ABS / ESP Controller

A complete Opel ABS pump normally consists of a hydraulic block, pump motor, solenoid valves and an electronic ABS / ESP control unit. The system helps prevent wheel lock during braking and, depending on the vehicle configuration, can also work with ESP, traction control and other stability-related functions.

When replacing an ABS pump in an Opel, the vehicle model alone is not enough to identify the correct unit. Astra, Corsa, Zafira, Combo, Antara, Mokka and other Opel models can use several different ABS systems depending on production year, engine, equipment and electronic configuration.

The most reliable method is therefore to compare the complete set of numbers from the original ABS assembly.

How to choose the correct Opel ABS pump

Before ordering, check all numbers printed or engraved on the original unit.

Important references can include:

• Opel / GM OEM number,
• ABS hydraulic pump number,
• ABS electronic control unit number,
• Bosch or ATE manufacturer reference,
• all final letters and suffixes,
• additional hardware or production codes where present.

Do not select an ABS pump only by vehicle model or appearance. Two units can look almost identical while using different electronic or hydraulic versions.

Opel ABS pump number and ABS ECU number

A complete ABS assembly can carry several different references because the hydraulic section and electronic controller can have separate identification numbers.

For example, an Opel unit may contain:

• one GM / Opel OEM reference,
• one Bosch or ATE hydraulic unit number,
• another Bosch or ATE ABS ECU number.

For accurate identification, it is best to compare all of them rather than relying on only one number.

Opel Astra H / Zafira B – 24447835 / ATE 10.0206-0114.4

A strong example is the Opel Astra H / Zafira B ABS pump 24447835 GP.

The main numbers are:

• GM 24 447 835 GP,
• 24447835 GP,
• ATE 10.0206-0114.4,
• 10020601144,
• ATE 10.0960-0525.3,
• 10096005253.

This is a good example of an ATE assembly carrying separate identification for the hydraulic section and electronic ABS controller.

ATE ABS numbers – 10.02... and 10.09...

ATE supplied many ABS systems used in Opel vehicles.

Depending on the system generation, an ATE assembly may carry numbers from families such as:

• 10.02...,
• 10.09...,
• 25.02...,
• 25.09....

These references can identify different parts or versions of an ABS assembly, so the complete number should always be retained.

Opel Astra J – 13412550 / 10.0206-0449.4 / 10.0960-4584.3

The catalogue also includes the Opel Astra J ABS pump 13412550 / ATE 10.0206-0449.4 / 10.0960-4584.3.

Important references include:

• 13412550,
• 10.0206-0449.4,
• 10020604494,
• 10.0960-4584.3,
• 10096045843.

Searching for both the Opel number and ATE references gives a much more precise result than searching only for “Astra J ABS pump”.

Opel Astra J – 13356789 ACB / ATE 10.0212-0663.4

Another Astra J version in the catalogue carries:

• 13356789 ACB,
• ATE 10.0212-0663.4,
• 10021206634,
• 10.0961-4522.3,
• 10096145223,
• 10.0619-3651.1,
• 28.5611-8103.3.

This clearly shows why an Opel Astra J ABS pump should not be selected only by model name. Different complete number combinations exist within the same vehicle generation.

Bosch ABS pumps for Opel

Bosch is another major ABS supplier used across the Opel range.

Common Bosch references found on Opel ABS assemblies include families such as:

• 026521...,
• 026523...,
• 026525...,
• 026580...,
• 026595...,
• 027300....

A shared prefix does not indicate compatibility. The full Bosch number and the corresponding GM / Opel number should be compared.

Opel Corsa C / Combo / Meriva / Tigra B – 13145396

One example is the Opel Corsa C / Combo / Meriva / Tigra B ABS pump 13145396 / Bosch 0265231443 / 0265800372.

The complete set of references includes:

• GM 13145396,
• Bosch 0 265 231 443,
• 0265231443,
• Bosch 0 265 800 372,
• 0265800372.

This combination is much more useful for identification than the general phrase “Opel Corsa ABS pump”.

Opel Corsa D – several Bosch ABS versions

Opel Corsa D is a good example of a model that can use several visually similar Bosch ABS assemblies.

Catalogue examples include:

• 13350598 / 0265251864 / 0265951752,
• 13350599 / 0265251865 / 0265951753,
• 13277813 / 0265230285 / 0265950402,
• 13282283 FF / 0265230332 / 0265951015,
• 13277812 FB / 0265232238 / 0265800422.

These numbers should not be treated as interchangeable simply because all units are listed for Corsa D.

Opel Corsa D – 13277813 / Bosch 0265230285 / 0265950402

One confirmed product is the Opel Corsa D ABS pump 13277813 / Bosch 0265230285 / 0265950402.

The main identifiers are:

• 13277813,
• 0265230285,
• 0 265 230 285,
• 0265950402,
• 0 265 950 402.

Opel Corsa D – 13350598 and 13350599

Two other Corsa D units demonstrate how even consecutive Opel and Bosch numbers can identify different versions:

• 13350598 / 0265251864 / 0265951752
• 13350599 / 0265251865 / 0265951753 AG6

The difference of a single final digit should not be ignored when selecting the replacement unit.

Opel Antara – 96817720 / ATE 25.0212-0319.4

For selected Opel Antara versions, the catalogue includes the ABS pump 96817720 / ATE 25.0212-0319.4 / 25.0926-4529.3.

Important numbers:

• 96817720,
• ATE 25.0212-0319.4,
• 25021203194,
• ATE 25.0926-4529.3,
• 25092645293.

Opel Mokka ABS pumps

Newer Opel models can use ABS systems from manufacturers other than Bosch or ATE.

For example, the catalogue includes the Opel Mokka ABS pump 42520669 / 688250455, supplied by Mando.

This is another reason to use the exact label information rather than assuming one manufacturer for every Opel model.

Common symptoms of an Opel ABS pump problem

Possible symptoms may include:

• ABS warning light remaining on,
• ESP / ESC or traction-control warning light,
• ABS function unavailable,
• loss of communication with the ABS module,
• intermittent ABS communication,
• pump motor or valve-related fault codes,
• internal ABS controller errors,
• incorrect wheel-speed information reported to other systems.

These symptoms do not automatically mean that the ABS pump is faulty. Proper diagnosis is important before replacing the assembly.

ABS warning light in an Opel – what else should be checked?

An ABS or ESP warning can also be caused by:

• wheel-speed sensors,
• sensor wiring,
• wheel bearing magnetic encoder rings,
• poor power or ground connections,
• fuses and relays,
• damaged connectors,
• CAN communication problems,
• steering-angle or other stability-control sensors.

Diagnostic fault codes and live sensor data should be checked before deciding that the ABS pump or controller requires replacement.

No communication with the Opel ABS module

If diagnostic equipment cannot communicate with the ABS controller, check:

• power supply to the module,
• ground connections,
• fuses,
• connector condition,
• damaged or corroded pins,
• CAN communication wiring.

No communication can be caused by internal electronic failure, but it can also result from a fault in the vehicle wiring.

Does an Opel ABS pump require coding after replacement?

Not every Opel ABS system uses the same replacement procedure.

Depending on the model and ABS / ESP generation, installation may require:

• coding or variant configuration,
• basic settings,
• steering-angle sensor calibration,
• other sensor calibration,
• clearing fault codes after repair,
• diagnostic activation of hydraulic functions.

Some correctly matched units may require fewer procedures. Coding should therefore be confirmed for the exact Opel model and ABS reference instead of assuming that every used pump must be programmed.

Bleeding the brake system after replacing an ABS pump

When replacement of the complete hydraulic ABS assembly requires disconnecting the brake lines, the brake system must be properly bled after installation.

Depending on the Opel model and ABS system, a diagnostic procedure may also be used to activate the internal pump and solenoid valves during bleeding.

This work should be carried out using the correct workshop procedure for the vehicle.

ABS control unit only or complete ABS pump?

If only the electronic section is required, see the ABS / ESP / ASR electronic control units category.

A complete ABS pump normally includes both:

• hydraulic ABS block and pump motor,
• electronic ABS / ESP control module.

Before ordering, determine whether the problem affects only the electronics or whether a complete hydraulic assembly is required.

How to search for an Opel ABS pump by part number

Useful long-tail searches include:

• Opel Astra H ABS pump 24447835 10020601144,
• Opel Zafira B ABS pump 10.0206-0114.4 10.0960-0525.3,
• Opel Astra J ABS pump 13412550 10096045843,
• Opel Corsa C ABS pump 13145396 0265231443,
• Opel Corsa D ABS pump 13277813 0265950402,
• Opel Corsa D ABS 13350598 0265251864,
• Opel Antara ABS pump 96817720 25021203194,
• Opel Mokka ABS pump 42520669 688250455.

Searching by the complete combination of Opel / GM, hydraulic pump and ABS ECU numbers is usually much more precise than searching only by model.
