When Do You Need a Diagnostic Check?
If you are experiencing any of these symptoms, a professional diagnostic check can save you time, money, and stress by identifying the root cause.
Engine Management Light
The most common reason for a diagnostic check. This warning can indicate hundreds of different faults — we will tell you exactly which one.
ABS / Traction Warning
ABS, ESP, or traction control lights can be caused by sensor issues, wiring faults, or module problems. A diagnostic pinpoints the cause.
Poor Performance
Loss of power, rough idling, misfires, or hesitation under acceleration. These often stem from faults that store codes in the ECU.
Airbag / SRS Light
An illuminated airbag light means the system has detected a fault. This needs diagnosing to ensure your safety systems will work in an emergency.
Transmission Issues
Harsh gear changes, slipping, or warning lights related to your automatic gearbox can be read and diagnosed with the right equipment.
Intermittent Faults
Problems that come and go can be the hardest to find. Our live data analysis can catch intermittent issues that standard code reads miss.

Professional Car Diagnostics You Can Trust
Modern vehicles rely on dozens of electronic control units to manage everything from engine performance to climate control. When something goes wrong, a warning light on the dashboard is often the first sign. But that light alone does not tell you what the problem is — that requires proper diagnostic equipment and the knowledge to interpret the results.
At Doyen Auto Services in Rutherglen, we use dealer-level diagnostic tools that go far beyond a basic code reader. Our equipment communicates with every module in your vehicle, retrieves detailed fault information, and allows us to run live tests and component actuations. This means we can find faults that cheaper tools simply miss.
Once we have identified the issue, we will explain it to you in plain English and provide a clear, honest quote for any repairs needed. We never carry out work without your approval, and there is never any pressure to get repairs done with us. We serve customers from across Glasgow, Rutherglen, Cambuslang, East Kilbride, Hamilton, and the wider area.
