Bosch – Engine Control Units, ABS Pumps and Automotive Electronics

Bosch is one of the world’s leading manufacturers of automotive electronics and original equipment components fitted at the factory in vehicles from many different brands. At Auto24parts.com, you can find a wide range of Bosch products, including engine control units, complete ABS pumps, electronic control modules, throttle bodies and accelerator pedal potentiometers.

Original Bosch parts are used in vehicles manufactured by BMW, Audi, Volkswagen, Mercedes-Benz, Opel, Peugeot, Citroën, Renault, Fiat, Volvo and Ford, among others. The used components available from our store are tested before sale, while selected engine control units can be prepared as Plug & Play, Virgin, IMMO OFF or ready for programming.

Find a Bosch Part by Part Number

The most accurate way to select a Bosch engine control unit, ABS pump or electronic module is to compare all the numbers shown on the original part label. The Auto24parts.com search engine allows you to find a product using its Bosch part number, the vehicle manufacturer’s OE number or the control unit designation.

Common Bosch part number prefixes include:

• 0 281... – diesel engine control units,
• 0 261... – petrol engine control units,
• 0 265... – ABS and ESP pumps and control modules,
• 0 280... – throttle bodies, sensors and fuel injection system components,
• 0 204... – braking system components,
• 0 212... – electronic modules and control units.

When selecting a replacement part, always compare the complete Bosch number and the vehicle manufacturer’s OE number. A similar housing or a partial number match does not necessarily mean that the component will be compatible with the vehicle.

Bosch Engine Control Units

Bosch engine control units manage the operation of petrol and diesel engines. They control functions including fuel injection, ignition, turbocharger boost pressure, the EGR system, DPF, AdBlue, Start-Stop and CAN communication with other vehicle modules.

Our range regularly includes Bosch ECUs from the following families:

• EDC15, EDC16 and EDC17,
• MD1 and MG1,
• ME7 and ME9,
• MED9 and MED17,
• MEVD and M7.

Each ECU family is available in numerous hardware and software versions. Before purchasing a replacement control unit, all part numbers should therefore be compared with those shown on the original ECU installed in the vehicle.

Our store offers, among others, BMW engine control units, Volkswagen engine control units and Audi engine control units.

Bosch ECU Preparation Options

Depending on the ECU model, memory type and immobiliser system used in the vehicle, a Bosch engine control unit may be available in one of the following configurations:

• Plug & Play – an ECU prepared using data from the original unit and ready for installation without additional programming.
• Virgin – an ECU that has been reset and prepared for adaptation to the vehicle.
• IMMO OFF – a version with the immobiliser function disabled, available only for selected ECU models.
• Ready for programming – an ECU intended for coding or adaptation by a suitably equipped workshop.

The available preparation options depend on the specific ECU part number. More information about available configurations can be found in our engine control unit category and on individual product pages.

Bosch ABS Pumps and ABS Control Modules

Bosch is one of the leading manufacturers of ABS, ESP and traction control systems. At Auto24parts.com, you can find complete ABS pumps, hydraulic units and electronic control modules for passenger cars and commercial vehicles.

A Bosch ABS system may be responsible for:

• preventing the wheels from locking during braking,
• operating the ESP, ESC and ASR systems,
• electronic brakeforce distribution through the EBD system,
• traction control and vehicle stability,
• communication with wheel speed sensors and driver assistance systems.

When selecting an ABS pump, compare the Bosch part number, the vehicle manufacturer’s OE number and the markings on both the electronic control module and hydraulic unit. Depending on the vehicle, coding, adaptation or brake system bleeding may be required after installation.

You can also browse our dedicated categories for Mercedes-Benz ABS pumps, Audi ABS pumps and Volkswagen ABS pumps.

Other Bosch Parts Available from Auto24parts.com

In addition to engine control units and ABS pumps, we also offer automotive control modules, accelerator pedal potentiometers and electronic throttle bodies.

Other Bosch components available from our store include:

• body and comfort control modules,
• transmission control units,
• electronic control modules,
• fuel injection system components,
• braking system components.

Why Choose an Original Bosch Part?

Original Bosch parts are designed to meet vehicle manufacturers’ requirements and work with factory-installed electrical and electronic systems. When choosing an engine control unit, ABS pump or automotive module, however, compatibility depends not only on the manufacturer but, above all, on matching all the relevant part numbers.

Selecting a component using the complete Bosch number and the vehicle manufacturer’s OE number reduces the risk of purchasing an incompatible ECU, an incorrect ABS pump or a module containing a different hardware or software version.

How to Select a Bosch ECU or ABS Pump

Before purchasing, compare the complete Bosch number, the vehicle manufacturer’s OE number, the control unit designation and the connector type. When selecting an ABS pump, also check the markings on the hydraulic unit and electronic control module.

When the numbers are illegible or you are unsure which product is suitable, send us a clear photo of the original part label or provide the vehicle identification number. We will check the available products and determine whether the ECU can be prepared as Plug & Play, Virgin, IMMO OFF or ready for programming.

Frequently Asked Questions About Bosch Parts

1. How can I find the correct Bosch ECU part number?

The Bosch number is usually printed on the ECU label and may begin with 0 281..., 0 261... or another prefix associated with a particular type of component. Copy the complete number without omitting any digits and compare it with the number shown in the product listing.

2. Is a matching Bosch number sufficient to select the correct part?

The complete Bosch number is one of the most important compatibility criteria, but you should also compare the vehicle manufacturer’s OE number, software designation, engine version and vehicle equipment. For ABS pumps, check the numbers on both the electronic and hydraulic parts.

3. What are the common symptoms of a faulty Bosch engine control unit?

Common symptoms include the engine failing to start, stalling while driving, rough running, reduced power, no diagnostic communication and fault codes relating to the injectors, ignition system, throttle body or immobiliser. Before replacing the ECU, the power supply, earth connections and electrical wiring should also be checked.

4. Does a used Bosch ECU require programming?

This depends on the selected configuration. A Plug & Play ECU is prepared for installation without additional programming. A Virgin unit requires adaptation, while an ECU supplied ready for programming must be coded by a suitably equipped workshop.

5. Can every Bosch ECU be prepared as IMMO OFF?

No. The availability of the IMMO OFF option depends on the ECU model, software version and immobiliser system used in the vehicle. The availability of this service must be confirmed for the specific ECU part number before ordering.

6. What are the common symptoms of a faulty Bosch ABS pump?

A faulty ABS pump or control module may cause the ABS and ESP warning lights to remain illuminated, prevent diagnostic communication or generate faults relating to the pump motor, pressure sensor or hydraulic valves. It may also cause incorrect brake pressure at individual wheels or uneven braking.

7. Does a Bosch ABS pump require coding after installation?

In many vehicles, replacing an ABS pump or control module requires coding, sensor adaptation or basic system settings. The exact procedure depends on the vehicle make, model and part number.

8. How can I select a Bosch part if the number is illegible?

Send us clear photographs of the label, connectors and complete component, together with the vehicle identification number. This information may allow us to identify the correct engine control unit, ABS pump or Bosch module and compare the available part numbers.
