Our Diagnostic Guarantee

If you’ve ever been victim of a garage fitting parts to your vehicle  that ultimately did not fix the fault then look no further. If we replace a part and it does not rectify the issue you were experiencing we will not charge you for that part.

You will never hear us saying things like “the computer said it was the…”

Plugging in a diagnostic computer and viewing fault codes is not a diagnosis, it’s only one part of out industry leading Eight step diagnostic process


By the time we replace a part you can be assured we have evaluated it, tested it & proved it was faulty using tools and equipment to bypass test the part so we can be 100% sure it requires replacement.

How can we offer this guarantee? Because we apply our industry leading Eight Step Diagnostic Process to every fault we’re presented with.

1. Diagnosis

Diagnosis starts with a consultation with you the vehicle owner, at this point we’ll gather relevant information about your vehicle and the issue you're experiencing.

2. understanding

We’ll take a look at the vehicle with you to ensure our understanding of the fault is in line with yours.

3. TESTing

Tests will now be performed in a logical order. We’ll use serial data tools, oscilloscopes, and gauges to lead us towards the root cause of your fault.

4. faults

Technical bulletins are consulted. This often outlines known faults for your vehicle, as well as software updates.

5. data

System data will be analysed and recorded. Once anomalies are witnessed we’ll formulate the test plans required to confirm the cause.

6. information

Technical information is consulted to ensure that the test plan will be accurate. Wiring diagrams are often used at this point.

7. testing

Using only the best test equipment, we’ll interrogate relevant systems for permanent and intermittent faults.

8. findings

Finally, we’ll document all of our initial findings and call you, explain our analysis and offer our recommendations.

Don't you just plug a computer in? 

Using computers is an essential part of our diagnostic evaluation and some faults can be found here. More often than not a single fault code can have many causes which is why tests are essential to finding the exact cause. Testing is a critical part of the process and ensures your vehicle is fixed the first time at the lowest possible cost to you the owner.

How much does an evaluation cost?

Every fault is different so the final cost depends on the type and number of defects on your vehicle. 

Our initial evaluation cost is £96 inc VAT and typically includes points one through to eight.

 Should the number of tests needed exceed the initial evaluation, then we’ll call with our recommendations and an estimate of costs going forward.
