Vehicle diagnostics and fault finding in Grantham

Finding the fault before replacing the part.

We inspect and test to find the cause and carry out the repair.

Start with what you have noticed

Tell us what happens and when you notice it. Mention any previous work on the fault when you speak to us.

A warning light has appeared

Tell us what the warning says and whether the vehicle behaves differently. Those details guide the testing and repair.

The vehicle runs differently

Tell us how the behaviour has changed, when it started and when you notice it. We use those details to target the inspection, testing and repair.

It will not start, or the fault comes and goes

Tell us what happens when you try to start the vehicle, or when the fault returns. We diagnose and repair starting and intermittent faults.

Testing follows the symptoms

A fault code can guide testing. It does not automatically mean a named part has failed.

We start with your symptoms, inspect the vehicle, then test and measure to establish the cause. The findings guide the repair.

Understand what is causing the fault

We explain what the tests show and talk through the repair options. We recommend replacement parts when the evidence supports them.

Fix the fault

We carry out the repair identified through the testing, rather than replace parts speculatively.

Check your vehicle with us

We assess cars, vans, light commercial vehicles and motorhomes of all makes and models. Suitability depends on the vehicle, its dimensions and weight, the fault and the work required.

Diagnostics questions

Can you help with a fault that comes and goes?

Yes. Tell us when it happens so we can target the testing and repair.

What happens after diagnosis?

We explain the findings and options, then carry out the repair. The evidence identifies which work or parts are needed.

Yes. We confirm the diagnostic charge when you arrange the appointment.

What should I write in the enquiry?
