From first symptoms to a documented result.

You should know what is being tested, what it will cost and what happens if the unit is not repairable. This is the route for postal module jobs and workshop enquiries.

Choose the right service

What do you need help with?

Describe the problem

Send the vehicle details, symptoms, fault codes and module label. A code alone is not a confirmed diagnosis.

Approve the scope

We confirm the available service, assessment charge and quotation process before work. Extra work requires approval.

Receive the handover

The final record explains the work completed, checks performed and remaining vehicle-side requirements.

A clear process

How it works

  1. Tell us about the fault

    Send the vehicle details, module label, symptoms and fault codes. Tell us what has already been tested and whether you are contacting us as a driver or a workshop.

  2. Agree the first job

    We confirm supported work, assessment fees, repair price or quotation process, delivery and payment arrangements. There is no fixed turnaround promise before assessment.

  3. Send or arrange collection

    Book the unit before dispatch, include the reference and package it securely. Collection charges depend on the packed parcel and route.

  4. Approve, repair and hand over

    We report findings and seek approval for extra work. After the agreed checks, the unit is returned with tracking and the handover information.

Before you book

Testing has limits

A bench setup can test supported functions under defined conditions. It cannot reproduce every vehicle fault, wiring issue or operating condition. We record the test scope and any limitations.

Repair, no fault found or beyond repair

All are possible outcomes of an assessment. The specific service listing and quotation explain charges and return arrangements. Assessment credits apply only where stated, for the same accepted repair.

Your questions answered

Can you diagnose from a fault code?

A code helps us plan checks, but does not prove a module is defective. Vehicle power, wiring, network and related components may need testing first.

Will you do extra work without asking?

No. Work beyond the approved scope is quoted for your approval.

Where can I check the repair?

Use your job reference when contacting us, or the repair tracking page where available.

Start with your vehicle or module details

Send clear label photos, the vehicle details and a short description of the problem. We confirm the appropriate service, price and next steps.
