Returns, Warranty Claims and Shipping Damage

Auto24Parts supplies tested automotive electronic parts for passenger cars, vans and commercial vehicles. Our range includes replacement engine control units, complete ABS hydraulic assemblies, transmission controllers, instrument clusters, vehicle modules and accelerator components.

Customers looking for a tested replacement ECU can browse dedicated categories for Peugeot engine control units, Opel ECUs, Alfa Romeo engine computers, Lancia engine controllers, Jaguar ECU modules and Mazda ECM and ECU units.

Use the buttons below to go directly to the section that matches your case.

Before sending a product back: contact Auto24Parts and include your order number, complete product reference, a description of the issue, diagnostic fault codes and photographs where available. This helps us identify whether the case concerns a return, a technical complaint or transport damage.

Eligible consumers may withdraw from a distance purchase within 14 days of receiving the product, subject to the applicable legal rules and the condition of the returned item.

Connector Seal and Housing Security Seal

Engine ECUs, ABS control modules, BCM, BSI and TCU units may carry two different seals:

• Connector seal – this may be broken when the part is connected to the vehicle. It confirms that the unit has been installed or tested, but does not automatically cancel the warranty.
• Housing security seal – this protects the controller against opening, disassembly and unauthorised internal modification. Damage to this seal may affect a return or commercial warranty claim.

Returning an ECU After Installation

A replacement engine computer may record vehicle-specific information during installation. This can occur with an Alfa Romeo ECU module, a Lancia engine controller or a Jaguar engine management unit. A returned controller may therefore require memory cleaning, removal of immobiliser data or additional diagnostic verification.

Where a restoration service is necessary and legally applicable, the standard service cost may be 50 EUR. The exact treatment of the return depends on the condition of the product and the applicable consumer rules.

How to Prepare a Return

• Contact Auto24Parts before dispatching the parcel.
• Include the order number and the reason for the return.
• Return the complete product with all supplied components.
• Protect connectors, pins, housings and hydraulic elements carefully.
• Use a tracked shipping service and retain the shipping receipt.

Return Address

A refund is normally processed using the original payment method. Before placing another order, customers can also review the store’s payment, delivery and product-selection information.

Auto24Parts provides a written commercial warranty for products sold through the store. Unless another period is stated in the product offer, used parts are covered for 6 months.

The commercial warranty concerns faults caused by the product itself. It does not replace or reduce statutory consumer rights.

What Is Checked Before Dispatch?

• manufacturer and OEM reference comparison;
• inspection of the housing, sockets, pins and labels;
• communication or data-reading checks where technically possible;
• verification of the selected preparation service;
• final order and product control before packaging.

Warranty verification may also depend on the type of product. A BMW ABS pump and control module, a Jeep ABS hydraulic unit or a Fiat ABS pump assembly may require correct hydraulic bleeding, coding, calibration or sensor learning after installation.

Likewise, an ECU for Peugeot, Opel, Alfa Romeo, Lancia, Jaguar or Mazda may require immobiliser adaptation or programming unless it has been prepared as a compatible Plug & Play unit.

If a purchased product does not operate correctly, contact Auto24Parts before returning it. A complete technical description helps us distinguish a product fault from an installation, coding or vehicle-system problem.

Information Required for a Technical Claim

• order number;
• complete product and manufacturer numbers;
• vehicle make, model, engine and year;
• all diagnostic fault codes;
• description of the vehicle symptoms;
• information about coding, programming or adaptation;
• photographs of the unit, connectors and installation;
• confirmation that the part was installed by a qualified workshop.

Complaint Procedure

1. Contact Auto24Parts and describe the issue.
2. Provide diagnostic information and photographs.
3. Wait for return instructions before sending the product.
4. Return the complete unit to Auto24Parts.
5. Our technicians inspect the part and perform communication or functional checks where possible.
6. A third-party workshop report may support the case, but final verification is carried out after the product arrives at Auto24Parts.
7. If the fault is confirmed, the unit may be repaired or replaced with a compatible product.
8. If repair or replacement is not possible, another remedy may be offered according to the applicable rules.

ABS Pump and Hydraulic Unit Complaints

For an ABS complaint, send all numbers from the electronic module, pump motor and hydraulic block. This is especially important for Chrysler ABS pump modules, SsangYong ABS hydraulic units and Jeep, BMW or Fiat ABS systems, where similar-looking units may use different coding or valve configurations.

When May a Commercial Warranty Claim Be Rejected?

• The housing has been opened or disassembled.
• The housing security seal has been damaged or removed.
• Unauthorised repair, soldering or software modification has been carried out.
• The unit was damaged through incorrect installation or polarity.
• There is evidence of water, fire, impact or mechanical damage.
• The fault was caused by wiring, voltage supply, CAN communication or another vehicle system.
• The product number, serial number or identification label has been removed or altered.

Can I return a used Peugeot or Opel ECU after installation?

A return may still be possible, but installation can affect the unit’s condition and stored data. Additional cleaning, restoration or diagnostic testing may be required.

Can I return a cloned Alfa Romeo, Lancia, Jaguar or Mazda ECU?

The physical controller and the completed individual service may be treated differently. Contact Auto24Parts before returning a unit prepared as Clone, IMMO OFF, Virgin or Plug & Play.

Does an ABS pump require coding after replacement?

Many BMW, Jeep, Chrysler, Fiat and SsangYong ABS systems require coding, calibration, sensor learning or correct hydraulic bleeding after installation.

How long is the warranty on used automotive electronics?

Used parts normally include a 6-month commercial warranty unless another period is stated in the product offer.

Do I need diagnostic fault codes for an ECU or ABS claim?

Fault codes are strongly recommended because they help identify whether the issue concerns the supplied component, coding, wiring or another vehicle system.

Does a broken connector seal void the warranty?

No. The connector seal may be broken during normal installation. The housing security seal should remain intact.

Who pays for return shipping?

The customer normally pays the cost of sending the product to Auto24Parts. If an accepted claim results in repair or replacement, Auto24Parts normally covers delivery of the resolved product back to the customer.

What happens after the product reaches Auto24Parts?

The unit is inspected and tested according to its type. We compare the reported fault with the condition, communication and available diagnostic results.

What should I do if the parcel arrives damaged?

Photograph the parcel, ask the courier for a damage report, keep all packaging and contact Auto24Parts immediately.
