01
Full System ECU Scan
We scan all available control modules - engine, transmission, ABS, airbag, and more - to build a complete picture of your vehicle's fault status.
ECU & Sensor Diagnostics
Warning lights and unexplained faults need more than a code reader - we use OEM-level tools and real expertise to find what is actually wrong.
What We Do
Deep diagnostic capability for modern vehicles.
Modern vehicles are complex, interconnected systems - and a warning light rarely tells the whole story. At Tune It Scotland, we go beyond basic fault code reading to carry out thorough ECU and sensor diagnostics using professional, OEM-level equipment.
Whether you have got a persistent warning light, an intermittent fault, a failed MOT, or an unexplained performance issue, we dig into the live data and system behaviour to find the actual root cause. Our performance-focused approach means we understand how engine systems interact - giving us an edge when diagnosing faults that other garages struggle to trace.
Services Offered
Comprehensive ECU and sensor diagnostics across all major systems
From engine management to transmission and emissions, we cover the full scope of modern vehicle diagnostics with the tools and expertise to match.
02
Live Data Analysis
We capture and interpret live sensor data to identify faults that do not always trigger stored codes - including intermittent and performance-related issues.
03
Sensor Testing & Fault Tracing
We test individual sensors - MAF, MAP, O2, temperature, pressure, and more - to confirm whether they are operating within correct parameters.
04
Injector & Fuelling Diagnostics
We assess injector performance and fuelling system behaviour through live data, identifying issues affecting power, economy, or emissions.
05
Advanced Fault Tracing for Persistent Issues
For difficult or recurring faults, we carry out in-depth system analysis - going beyond fault codes to trace the underlying cause.
How We Work
Methodical, data-driven fault finding from start to finish.
Good diagnostics are about interpretation, not just scanning. Our process combines professional tooling with genuine expertise to get to the real answer.
01
Connect
Full vehicle scan across all control modules - capturing every stored and pending fault code along with live system data.
02
Analyse
We interpret fault codes in the context of live data readings, cross-referencing symptoms with system behaviour to identify the true fault source.
03
Test
Where needed, we carry out targeted sensor or system tests to confirm the diagnosis before any repair work is recommended.
04
Report & Advise
We provide a clear explanation of what we have found - honest, jargon-free advice on what needs to be done and why.
