Modern Cars Need Modern Diagnostics
WHAT WE DIAGNOSE
Check Engine Light
Why is it on? Emissions issue? Misfire? Bad sensor? We read the codes and tell you what's happening.
Transmission Warning Light
Shift issues, fluid pressure problems, clutch wear?
ABS & Brake Warnings
Sensor faults, brake pad wear, system issues.
Electrical Gremlins
Battery drain, charging problems, module faults.
Suspension & Steering Warnings
Air suspension faults, ride height, steering angle sensor and power steering warnings.
Performance Issues
Hesitation, rough idle, poor fuel economy—diagnostics narrow it down.
PRE-PURCHASE INSPECTIONS
Thinking about buying a used car? Have us inspect it first. We check:
- Engine condition
- Electrical system
- Hidden corrosion or accident damage
- Transmission history
- Suspension & brakes
- Service history verification
NCT PREPARATION
NCT coming up? We can diagnose what's wrong and fix it before the test.
More Than Reading a Fault Code
A fault code tells you which system has reported a problem – it does not tell you which part has failed. Replacing parts based on a code alone is how drivers end up paying for repairs that do not fix the fault. Our diagnostic process goes further. We read the codes, look at live data from the sensors, and test the wiring and components involved using an oscilloscope and multimeter where needed. Many of the faults we find are not failed parts at all, but corroded connectors, damaged wiring or water getting into a control unit. Finding the real cause first means the repair is done once.
Common Reasons Drivers Book a Diagnostic
- Engine management, ABS, airbag or AdBlue warning light on the dash
- Car going into limp mode or losing power
- Battery going flat overnight
- DPF or EGR warnings on diesel cars
- Intermittent faults that another garage could not find
- Checking a used car before buying it
Frequently Asked Questions
How long does a diagnostic take?
A standard scan and initial assessment is usually done within an hour. Intermittent or electrical faults can take longer to trace – we will keep you informed.
Can I keep driving with a warning light on?
It depends on the light. A red warning, a flashing engine light or a coolant or oil warning means stop and get it checked. An amber light usually means the car can be driven carefully, but it should be looked at soon – small faults often become expensive ones.
Another garage already replaced a part and the fault came back. Can you help?
Yes. This is a large part of our work. We test the whole circuit rather than assuming the part is at fault.
Do you carry out pre-purchase inspections?
Yes. Before you buy a used car we can check the engine, gearbox, electrics, suspension, brakes and stored fault codes, and tell you honestly what we find.
