Proper Fault Finding
More Than Just Reading Codes.
A fault code can tell us where the vehicle has detected a problem, but it does not always tell us what actually caused it.
The aim is to use diagnostic information alongside live vehicle data and testing to understand the fault before unnecessary parts are replaced.
That gives you a clearer idea of what needs attention and what the sensible next step should be.
When To Book Diagnostics
What Can We Investigate?
Poor Running
Rough running, hesitation, misfires, inconsistent idle or unusual engine behaviour.
Loss Of Power
Reduced performance, limp mode or unexpected loss of engine power.
Sensor Faults
Investigating suspicious sensor readings and sensor-related vehicle issues.
Electrical Issues
Selected vehicle electrical and electronic faults where diagnostic testing may help.
Unknown Problems
When something clearly is not right, but you are unsure where to start.
Our Process
Diagnose Before Replacing.
01 / LISTEN
Understand The Issue
We start with the symptoms and what you have noticed from the vehicle.
02 / SCAN
Vehicle Scan
We check relevant vehicle control modules and available stored diagnostic information.
03 / ANALYSE
Live Data & Testing
Where appropriate, live data and further testing can help narrow down the likely cause.
04 / ADVISE
Explain The Findings
We explain what has been found and what the sensible next step should be.
Live Vehicle Data
See What The Vehicle Is Actually Doing.
Where appropriate, live data can help us look beyond stored fault codes and see how sensors and vehicle systems are behaving while the issue is present.

Diagnostics FAQ
Common Questions.
Can you diagnose an engine management light?
Yes. Diagnostic equipment can be used to check stored fault information and investigate the reason the warning light has appeared.
Can diagnostics be carried out at my home?
Many diagnostic jobs can be carried out as a mobile service, provided the vehicle is in a suitable and safe location.
Do you offer live data and datalogging?
Yes. Live vehicle data can be useful for both diagnostic work and performance-related investigation. Relevant datalogging can also form part of ECU remapping and tuning verification where supported.
Does a fault code tell you exactly which part is faulty?
Not always. A fault code normally identifies the system or condition where a problem has been detected. Further checks may be required to identify the actual cause.
Can you diagnose loss of power or limp mode?
These symptoms can often be investigated using fault information, live data and additional testing where appropriate.
What information should I send when booking?
Your registration, make and model, the warning lights or symptoms you are experiencing, and any recent repair work can all help when discussing the job.
