Misfires, emissions faults and sensor failures identified with live data from the ECU. We find the cause before replacing parts.
Diagnostics
Car Diagnostics in Stonehouse and Stroud
Warning light on? Unusual fault? We plug into your vehicle's ECU properly, read every fault code, and tell you exactly what is wrong before quoting for any repair. No guesswork, no parts replaced unnecessarily.
Diagnostics
We Read the Fault Properly
A warning light does not always mean an expensive repair. Most garages clear the code and hope for the best. We connect to your vehicle's ECU with professional diagnostic equipment and read every stored and pending fault code properly.
We then test the relevant component or sensor to confirm what has actually failed before ordering any parts. You get a plain-English explanation of the fault, what it means for your car, and a written quote before any work begins.
If it does not need fixing yet, we tell you that too.
What We Check
Common Diagnostic Jobs at Bath Road Garage
ABS and Safety Systems
Brake and stability warning lights investigated before any parts are ordered. We test the component, not just clear the code.
Electrical Faults
Battery, charging system and wiring issues on modern and older vehicles. Intermittent faults traced properly.
Air Conditioning Faults
AC not cooling, strange smells or compressor issues diagnosed before re-gas or repair is recommended.
Transmission and Gearbox
Gearbox warning lights, slipping or difficulty selecting gears investigated with diagnostic equipment before assessment.
Suspension and Steering
Electronic suspension faults, power steering warnings and ride height issues traced with the correct equipment.
The Process
How It Works
1
Plug In and Read
We connect to your vehicle's ECU with professional diagnostic equipment and pull every stored and pending fault code.
2
Test the Component
We do not just read the code. We test the relevant sensor, wiring, or component to confirm what has actually failed.
3
Explain in Plain English
We tell you what the fault is, what it means, and whether it is urgent or can wait. No jargon.
4
Quote Before We Touch Anything
You get a written quote before any repair starts. Nothing happens without your agreement.
Why It Matters
Why Dealer-Level Diagnostics Matter
A basic code reader from a parts shop clears the warning light. It does not tell you why it came on. At Bath Road Garage we use the same grade of diagnostic equipment as main dealers. That means we can see live data from every sensor, run component tests, and pinpoint the actual fault.
It saves time and it saves money. You do not pay for parts that do not need replacing. Drivers from Stonehouse, Stroud and across GL10 use us when other garages have been unable to find the fault.
All Makes Accepted
