Vehicle Warranty Repairs in Wrexham - Martin Motor Group

Martin Motor Group is an independent Bosch Car Service garage experienced in carrying out repairs for customers with third-party vehicle warranty policies.

If your vehicle develops a fault and you have a warranty in place, dealing with the warranty company, arranging diagnostics, obtaining authorisation and organising the repair can sometimes become complicated.

We can manage the process for you from start to finish.

Rather than the customer having to coordinate between the garage and warranty provider, our team can handle the administration and technical side of the claim while carrying out the necessary diagnosis and repairs.

How Our Warranty Repair Service Works

1. Bring Your Vehicle to Us

Contact Martin Motor Group and let us know that your vehicle has developed a fault and that you have a warranty policy.

We will need the details of your warranty provider and policy so that we can establish the claim requirements.

2. Professional Diagnostics

Our technicians will diagnose the vehicle to establish the cause of the fault.

As a Bosch Car Service garage with specialist diagnostic and auto-electrical capabilities, we can investigate everything from mechanical faults to more complex electrical and electronic problems.

A proper diagnosis is essential because warranty companies will normally require evidence of the fault before they will authorise a repair.

3. We Deal With the Warranty Company

Once the fault has been identified, we can contact the warranty provider on your behalf and supply the information required to support the claim.

Depending on the warranty company, this may include:

  • Diagnostic reports
  • Fault codes and test results
  • Technician findings
  • Photographs or supporting evidence
  • Repair estimates
  • Parts and labour information
  • Service history or other documentation requested by the warranty provider

We can liaise directly with the warranty company while the claim is being assessed.

4. Warranty Authorisation

Where the repair is covered by the customer’s policy, we will work with the warranty company to obtain the necessary authorisation before proceeding.

Warranty coverage and the amount authorised will depend on the individual policy, its terms and conditions, labour-rate limits, parts allowances and any applicable excess.

We will explain the outcome to the customer before carrying out chargeable work.

5. Repair

Once authorised, our technicians can carry out the agreed repair.

Being able to diagnose and repair the vehicle in the same workshop means the customer doesn’t need to move the vehicle between different garages, diagnostic specialists and repair centres.

6. Completion & Warranty Administration

Following the repair, we can complete the relevant paperwork and provide the warranty company with the documentation required to conclude the claim.

Our aim is to make the process as straightforward as possible for the customer:

One garage. One point of contact. From initial diagnosis through to completed repair.

Important Information

Warranty policies vary considerably between providers.

Martin Motor Group cannot guarantee that a repair will be accepted or paid for by a warranty company.

All claims remain subject to the individual warranty provider’s terms, conditions, exclusions and authorisation.

Diagnostic charges and our warranty administration fee may be payable by the customer where these costs are not covered by their warranty policy.

Any contribution, excess, labour-rate shortfall or non-covered repair cost will be discussed with the customer where applicable.

Martin Motor Group is proud to be part of the Bosch Car Service network, and as such we are 100% committed to upholding and surpassing the high standards that both Bosch and our customers rightly expect of us. We are accredited by the IMI, and pleased to also be affiliated with 1link, the leading UK network for providers of fleet management services.
