🔧 DIAGNOSTICS — What we actually do
When we “run diagnostics”, it’s not just plugging a car into a machine and waiting for magic. Here’s what really happens behind the scenes:
• Live data checks
We read the vehicle’s real‑time information — temperatures, pressures, fuel trims, boost levels, sensor activity — to see what’s happening right now while the engine is running.
• Fault code analysis
If the car has stored fault codes, we don’t just read them. We check when they appeared, how often, and what conditions triggered them. A fault code is a clue, not a diagnosis.
• Component testing
We test individual parts: injectors, EGR valves, DPF pressure sensors, turbo control, airflow meters, thermostats, and more. This shows whether a part is responding correctly or failing under load.
• System behaviour under load
We run the vehicle under different conditions — idle, acceleration, cruising — to see how systems behave when stressed. Many faults only appear when the car is actually working hard.
• Mechanical checks
Not everything is electronic. We inspect hoses, wiring, vacuum lines, boost pipes, leaks, blockages, and physical wear that a computer can’t see.
• Root‑cause reporting
Once we’ve gathered the evidence, we explain why the fault is happening — not just what the code says — and outline the most cost‑effective repair path.
Diagnostics = evidence‑based fault finding, not guesswork, not parts‑swapping, and not just “plugging it in”.
If your car isn’t running right, this is how we get to the bottom of it — properly, thoroughly, and with the data to back it up.
