Fault Finding & Vehicle Diagnostics
When something doesn’t feel right with your vehicle, the hardest part is often working out exactly what is causing the problem.

Fantastic service, resulting in an outstanding job! Shaun is excellent value for money. Will always take the car to him.
At 1st Call, we provide professional fault finding and vehicle diagnostics for cars and light commercial vehicles from our workshop in Chawston, near St Neots. With more than 25 years’ experience in the motor trade, we combine practical mechanical knowledge with modern diagnostic equipment to identify faults accurately and recommend the right repair.
Whether your vehicle has a warning light on the dashboard, is difficult to start, has lost power, is running unevenly or has developed an intermittent fault, we can investigate the problem and help get to the root cause.
Engine Management Lights & Warning Lights
If your Engine Management Light (EML) or another warning light appears on the dashboard, it is important not to ignore it. A warning light can indicate anything from a relatively minor sensor issue to a fault that could affect vehicle performance, emissions or reliability.
We can carry out a diagnostic check to read stored fault information from the vehicle and use this as the starting point for further investigation.
A fault code does not always tell you exactly which part needs replacing. It identifies where the vehicle has detected a problem, which is why experience and proper fault finding are so important.
More Than Just Reading Fault Codes
Modern diagnostic equipment is an extremely useful tool, but effective diagnosis involves more than simply connecting a computer to the vehicle.
A fault code may be caused by a failed component, damaged wiring, a poor electrical connection, a sensor giving incorrect readings or another underlying mechanical problem.
Our approach is to use diagnostic information alongside physical testing and inspection to determine what is actually causing the issue.
This helps avoid unnecessary replacement of parts and gives you a clearer understanding of what work your vehicle really needs.
Experienced Vehicle Diagnostics Near St Neots
Based in Chawston, Cambridgeshire, close to St Neots and the A1, we provide diagnostic and fault-finding services for customers throughout Cambridgeshire and Bedfordshire.
With more than 25 years in the motor trade, we have developed the practical experience needed to investigate difficult faults and understand how the mechanical and electrical systems of a vehicle work together.
Our aim is straightforward: identify the real problem, explain what we have found and recommend the most appropriate repair.
Common Problems We Can Investigate
We can diagnose a wide range of vehicle faults, including:
Our work includes:
- Engine management warning lights
- Vehicles that are difficult or slow to start
- Complete non-starting vehicles
- Loss of engine power
- Poor or uneven running
- Intermittent faults
- Battery and charging problems
- Starter motor and alternator faults
- Sensor faults
- Electrical and wiring problems
- Unusual engine behaviour
- Increased fuel consumption
- Dashboard warning messages
- Lighting and electrical system faults
- Problems that keep returning
Even if you cannot describe the fault technically, that is not a problem. Tell us what you have noticed, when it happens and how the vehicle behaves, and we can begin the investigation from there.
Diagnosing Intermittent Vehicle Faults
Some of the most frustrating vehicle problems are those that do not happen all the time.
You may have a warning light that appears and disappears, a vehicle that only struggles to start occasionally or an electrical component that works one day and fails the next.
Intermittent faults can require more detailed investigation because the problem may not be present when the vehicle first arrives at the workshop.
With extensive experience in both mechanical and auto electrical fault finding, we can investigate these types of problems and look for the underlying cause rather than simply treating the immediate symptom.
Mechanical & Electrical Diagnostics
One of the advantages of bringing your vehicle to 1st Call is that our experience covers both mechanical repairs and auto electrics.
Many faults do not fall neatly into one category. A problem that initially appears electrical may ultimately be caused by a mechanical component, while a mechanical symptom may be the result of an electrical or sensor fault.
Being able to investigate both sides of the vehicle allows us to take a broader view of the problem and helps reduce the guesswork involved in diagnosis.
Non-Starting Vehicles
If your car or van will not start, there can be many possible causes.
The problem could relate to the battery, starter motor, alternator, ignition system, wiring, sensors, fuel delivery or another mechanical or electrical component.
Rather than assuming the obvious part is responsible, we can carry out the necessary checks to determine why the vehicle is not starting.
If the vehicle cannot be driven to our workshop, we can also arrange collection from your home or workplace.
Have You Got a Warning Light or Vehicle Fault?
If your vehicle has developed a warning light, starting problem, electrical fault or unexplained change in performance, get in touch.
Tell us what vehicle you have and what symptoms you have noticed, and we can advise you on the next step and arrange a diagnostic inspection.
