Modern vehicles have hundreds of complex electronic components. When a warning light appears, the root cause isn't always obvious. Our Bosch diagnostic equipment interfaces directly with your vehicle's ECU to read error codes accurately.
Modern vehicles are extraordinarily complex machines. Today’s cars contain dozens of electronic control units (ECUs) managing everything from the engine and transmission to the brakes, airbags, emissions systems, climate control, and driver assistance features. When a warning light appears on your dashboard — whether it is the engine management light, the ABS warning, the tyre pressure monitor, or any other indicator — the root cause may not be immediately obvious, even to an experienced technician working without the right equipment.
At Windsor Garage Coventry, we use state-of-the-art Bosch diagnostic equipment to interface directly with your vehicle’s electronic systems and read the fault codes stored by each ECU. This gives our technicians a full, accurate picture of what is happening inside your vehicle — not a guess, not a rough estimate, but a precise, data-driven diagnosis. This means we can identify faults quickly and accurately, saving you time and money compared with the trial-and-error approach that less well-equipped garages may resort to.
Crucially, our professional-grade diagnostic equipment means you do not need to pay main-dealership prices for a dealership-quality diagnosis. Many Coventry drivers assume that a warning light means a trip to the manufacturer’s franchised dealer — but that is simply not the case. Windsor Garage has the same diagnostic capability as a main dealer, at a fraction of the cost. We cover all major vehicle makes and models, including European, Asian, and American vehicles.
Our vehicle diagnostic service checks for faults across a comprehensive range of systems, including engine management, fuel injection, ignition, transmission, ABS and traction control, airbag and SRS systems, tyre pressure monitoring (TPMS), emissions and exhaust systems, lighting, climate control, and comfort systems. Once the diagnostic scan is complete, we will explain the findings to you in plain English, give you a clear, itemised quote for any work required, and proceed only with your approval.
It is important to understand that simply clearing a fault code does not fix the underlying problem. The warning light will return if the root cause is not addressed. At Windsor Garage Coventry, we always diagnose and repair the cause — not just the symptom. Our goal is to get your vehicle running correctly and keep it that way.

A vehicle diagnostic check involves connecting specialist equipment to your car’s OBD (On-Board Diagnostics) port to read fault codes stored by the vehicle’s electronic control units (ECUs). This covers the engine, transmission, ABS, airbags, emissions system, and more. The results help our Coventry technicians pinpoint the root cause of a warning light or performance issue quickly and accurately.
The engine management light (EML) can illuminate for a wide range of reasons, from a loose fuel cap or a faulty sensor to a more serious issue with the catalytic converter, fuel injectors, or ignition system. The only way to know for certain is a diagnostic scan. We will read the fault codes, explain what they mean in plain English, and give you a clear quote for any work required.

A proper diagnostic check identifies the root cause so it can be repaired correctly. At Windsor Garage Coventry, we always address the cause, not just the symptom.
Yes. Modern vehicles are highly complex electronic systems, and many faults are electrical in nature — from faulty sensors and wiring issues to ECU faults.
