E-mail: contact@auto24parts.com

How can I check whether a product is available?

The current availability status is shown on the product page. If a part is unavailable or you cannot find the required reference, contact us with the complete part number. We may be able to locate another compatible unit or inform you when the product becomes available again.

How do I select the correct electronic part for my vehicle?

The most important information is the complete part number shown on the original unit. The vehicle make and model alone are often not sufficient to confirm compatibility.

Send us a clear photo of the label and, when possible, the vehicle model, year, engine type and transmission version. We will compare the available references before you order.

Can two parts that look identical have different functions?

Yes. Control units with similar housings may contain different hardware, software, coding or vehicle configuration. Always compare all Bosch, ATE, Continental, Siemens, Delphi, Magneti Marelli, Denso and original vehicle manufacturer numbers.

Are engine control units tested before dispatch?

Engine control units are checked when they enter our warehouse and verified again before dispatch. The scope of testing depends on the ECU design and the diagnostic or data-reading methods available for that unit.

Can an ECU be prepared as Plug & Play?

For selected models, an ECU can be prepared as Plug & Play, Virgin, IMMO OFF, automatically programming or cloned from the original controller. Availability depends on the exact ECU number, vehicle system and software version.

What is a Virgin ECU?

A Virgin ECU has been cleared of the previous vehicle data and prepared for new programming. After installation, it must normally be programmed and adapted to the vehicle using suitable diagnostic equipment.

What does IMMO OFF mean?

IMMO OFF means that the immobiliser function has been disabled in the engine control unit. This option is available only for selected ECU models and vehicle systems.

Do I need to send my original ECU for cloning?

Yes. To clone an ECU, we normally need the original controller so that the immobiliser data, coding and vehicle configuration can be read and transferred to the replacement unit.

Before ordering, read our guide to ECU preparation options or browse available engine control units .

Do you sell complete ABS pumps?

Yes. We supply complete ABS pumps consisting of an electronic control module and hydraulic unit. Before ordering, compare all numbers shown on the pump, controller and hydraulic block.

Does an ABS pump require coding after installation?

It depends on the vehicle and ABS system. Some units may require coding, calibration, adaptation or transfer of the original configuration after installation. The workshop should verify the procedure using suitable diagnostic equipment.

Do you also sell transmission controllers and vehicle modules?

Yes. Our range includes automatic transmission control units, BSI, BSM and BCM modules, fuse boxes, comfort controllers, instrument clusters, accelerator pedals and other automotive electronic parts.

How can I check the status of my order?

Order status information is sent to the e-mail address used during checkout. Registered customers can also sign in to their account to view current and previous orders.

Can I change my order after placing it?

Changes may be possible before the order has been prepared or dispatched. Contact us as quickly as possible if you need to change the delivery address, product, payment method or shipping details.

Can I cancel an order?

An order can normally be cancelled only before preparation or dispatch. Specially prepared, programmed or cloned products may already be undergoing an individual service, so contact us immediately if cancellation is required.

Which courier companies do you use?

How long does delivery take?

Express delivery within Europe usually takes approximately 1–2 business days after dispatch. Delivery to worldwide destinations usually takes approximately 4–5 business days. Customs clearance and remote locations may extend these times.

Does a prepared ECU take longer to dispatch?

Yes. If the engine ECU requires unlocking, Virgin preparation, IMMO OFF, programming or cloning, allow approximately 1–2 additional business days before dispatch.

Will I receive a tracking number?

Yes. After dispatch, the DHL or FedEx tracking number is sent to the e-mail address provided with the order.

How much does delivery cost?

The exact shipping cost is displayed during checkout and depends on the destination country, parcel weight, dimensions and courier service. Large or unusually heavy products may have a higher shipping charge.

Depending on the case, we may ask you to return the complete product for verification, repair or replacement.

Can I return a product purchased online?

A standard product may be returned in accordance with the conditions stated on our returns page, provided it has not been used, damaged or modified and the security seal remains intact. Services such as programming, cloning and individual ECU preparation are not refundable once completed.

What should I do if the parcel is damaged?

Inspect the parcel before accepting it. If the packaging is visibly damaged, report it to the courier and document the condition with photographs. Contact us as soon as possible with the order and tracking numbers.
