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.
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
