Why proper diagnosis saves money later
We look past the code
Stored fault codes point us in a direction, but testing confirms the cause.
Intermittent faults get real tests
Live data, waveforms and heat patterns help us catch faults that come and go.
You approve extra time
If a fault needs deeper investigation, we agree the next cost before carrying on.
More than a quick code read
A warning light and a cheap scan result do not always tell the full story. Proper car fault diagnosis means checking the systems involved, reading live data, testing likely causes, and confirming what has actually failed before parts are fitted. We use professional equipment, including Autel MaxiSys and Launch X431 Pro3S tools to investigate warning lights, ECU faults, running issues, and electrical problems, so you get a clear answer instead of a list of guesses.
How we trace the fault before repairs
We start by asking when the problem happens, what changed before it started, and whether there have been recent repairs, noises, or warning messages. From there we scan the relevant systems, compare live readings, carry out electrical or mechanical checks, and use deeper tools such as oscilloscope testing, thermal imaging, and remote dealer-level access where needed. The first stage costs £104.99, including VAT, for up to one hour, and if a fault needs more time, we agree with you before carrying on.
Frequently asked questions
What does the diagnostic charge include?
The £104.99 including VAT charge covers up to one hour of investigation with no separate call-out fee. In that time we discuss the symptoms, scan the relevant systems, test likely causes and explain what we have found and what should happen next.
Can you diagnose a fault if no warning light is on?
Yes, many faults never put a light on the dash. Poor running, intermittent starting, odd noises, flat spots and electrical glitches can still be traced through live data, hands-on checks and targeted testing of the systems involved.
How should I prepare for a diagnostic visit?
It helps if you note when the fault happens, any warning messages, unusual noises, recent repairs and whether the vehicle is still driveable. That background can narrow the test path quickly and make the first hour of diagnosis far more useful.
