Our service

Repair. Test. Return.

Find a listed repair or send an unlisted unit for assessment. Here’s how to prepare the unit, send it safely and understand what happens next.

Find a repair Send your unit

Step 1

Choose the correct service route.

Search by part number, fault code or vehicle. If the correct service is listed, you can order and pay online before sending. If you cannot find it, you can still send the part straight in for assessment without asking first.

Repair my original unit Best when retaining original data and coding matters. Browse repair services Exchange where available A replacement route for selected units where stock is available. View exchange options Send for assessment For an unlisted service, provide the unit, fault and return details before sending. Create assessment form

No online listing or prior enquiry is required. You can send the part directly for assessment. Include clear contact, vehicle, part and fault information inside the parcel so it can be identified and booked in without delay.

Step 2

Package the part securely.

Whether you have paid online or are sending the unit for assessment, use a strong box, adequate cushioning and protect electrical connectors or fragile housings. Place the packing slip or a clear written note with all relevant details inside the parcel.

  • The electronic unit or complete assembly specified on the service

  • Your order or packing-slip reference, or your name, phone number, email and return address

  • Vehicle details, the part number, a clear fault description and any relevant diagnostic codes

Pay upfront or at the end: Payment can be made through the website before sending, or after the unit has been assessed and the service is completed. Whichever route you use, the parcel still needs the full job details inside.

Protect the unit: Drain fluids where applicable. Do not allow contamination, unprotected connectors or a loose heavy unit to move inside the parcel.

Important before sending

Has the unit been worked on before?

We are happy to assess units that have previously been opened, repaired or modified. In most cases there is no additional charge simply because another repair has been attempted, but it is important that we know because previous intervention can change the diagnostic picture.

Previous work can introduce new faults.Components, PCB tracks, connections, software, housings or seals may already have been altered or damaged. Those changes can create symptoms that were not part of the original vehicle fault.

We may repair an induced fault rather than the original cause.An earlier intervention may have created the fault we can see and test. Repairing that fault does not necessarily mean the unit was the original cause of the vehicle's problem if an underlying issue remains elsewhere.

Not every future symptom can be visible during assessment.A unit may test correctly after the reported fault is repaired, but another pre-existing, intermittent or induced issue can appear later if it was not active or detectable at the time.

Please tell us even if the history is uncertain. Include any known previous opening, soldering, component replacement, coding, water ingress or physical damage on the repair request. If we find extensive pre-existing damage, missing or incorrect components, or substantially more work is required, we will contact you before proceeding with any additional charge.

Step 3

Inspection, diagnosis and repair.

When the parcel arrives it is matched to the online order, packing slip or enclosed contact and job details. Units sent without an order are assessed in the same way, and payment can be handled at the end of the service.

ArrivalJob matched

The parcel is linked to the order, packing slip or enclosed customer details.

DiagnosisFault confirmed

The symptoms and fault codes guide inspection and testing.

VerificationChecked before return

The completed repair is verified where the system allows.

Step 4

Return, refit and final vehicle checks.

Once returned, refit the unit correctly and check the vehicle for related wiring, battery, mechanical or calibration issues where applicable. The service listing explains any coding or installation requirements.

Refit correctlyFollow the correct installation procedure and protect plugs, pins and housings.

Complete vehicle checksResolve related power, ground, wiring, coding or calibration issues.

Keep the order referenceUse it for invoices, warranty support and questions after refitting.

Service details

Useful answers before you send.

Practical information to help us identify, receive and process your unit without unnecessary delay.

Do I need to order or ask before sending?

No. If the correct service is listed, ordering online is the quickest route and allows you to pay upfront. If you cannot find it, you can send the unit directly for assessment without asking first. Include a packing slip or a clear note with your contact, vehicle, part and fault details so it can be booked in correctly.

Create packing slip
Do I need to include a packing slip?

Use the packing slip wherever possible and place it inside the parcel. If you cannot print it, include a clear written note with your name or company, phone number, email, return address, vehicle details, part number, fault description and diagnostic codes.

Create packing slip
What if the unit has been opened or repaired before?

Yes. Please tell us if the unit has already been opened, modified or repaired, even if you do not know exactly what was done. Previous intervention does not automatically stop us assessing or repairing the unit and, in most cases, does not add a charge by itself.

Earlier work can introduce additional faults or change the symptoms we are diagnosing. In some cases we may repair a fault created by a previous intervention while the vehicle's original underlying issue remains elsewhere, or another pre-existing or intermittent issue may only become apparent later. If extensive damage, missing or incorrect components, or substantially more work is required, we will contact you before any additional charge.

How should I package the unit?

Use a strong box with enough cushioning to prevent movement. Protect plugs, exposed pins, fragile plastics and mounting points, and do not allow the unit to move freely inside the parcel.

How can I send the unit?

You can use your preferred tracked courier or ask us to arrange a collection. Postage added during checkout covers the return journey only. If you are paying at the end, return postage can be included with the final payment. Consider suitable insurance when sending high-value units.

Arrange collection
When do I pay?

You can pay upfront through the website when ordering, or send the unit for assessment and pay at the end of the service. The parcel must include the same full contact, vehicle, part and fault information whichever payment route you choose.

What happens if no fault is found?

If the reported fault cannot be confirmed during testing, we will advise you. The applicable testing or diagnosis fee and return postage will still be payable.

What if the unit cannot be repaired?

We will advise you if a reliable repair is not possible. Where available, we may offer an exchange or replacement route instead, but we will not continue without discussing it with you.

What is covered by the warranty?

Warranty cover and duration are shown on the relevant repair or exchange service. Water ingress, physical damage, incorrect fitting and faults elsewhere on the vehicle may be excluded; see the Warranty Policy for full details.

Warranty information
Do you remove, refit or code the unit?

Our service covers the component itself. Removal and refitting are not included, and some units may still require vehicle-side coding, calibration or setup after refitting.
