Car Diagnostic Testing
Engine warning light on, or something not quite right? Our professional diagnostic equipment reads the fault codes and points us to the exact problem — so you get a proper fix, not guesswork. Right here in Hornsea and across East Yorkshire.
Accurate Fault-Finding
Modern cars throw countless codes. Our job is to read them, interpret what's actually wrong and fix it — the first time.
Engine Warning Lights
Check engine or warning light on? We connect and read the trouble codes, then explain in plain English what's wrong and what's needed.
Full System Scanning
We scan across engine, transmission, ABS, airbag, emissions and more — not just the obvious system — to catch hidden issues early.
Intermittent Faults
Faults that come and go can be the hardest to pin down. We use diagnostic data to catch issues that only appear under load or at certain speeds.
Performance Checks
Loss of power, poor fuel economy or rough running? Diagnostic live data helps us find the cause quickly.
No Guesswork
We don't throw parts at a problem. We diagnose accurately first, so you only pay for what actually needs fixing.
Then We Fix It
Once diagnosed, our workshop can usually carry out the repair in-house — one stop from light to solution.
Stop The Guesswork
A warning light doesn't mean you need to replace half the car — it means your car is signalling a specific problem. With proper diagnostic equipment and experienced technicians in Sigglesthorne near Hornsea, we pinpoint the real cause and carry out the repair.

Car Diagnostics FAQs, Hornsea & East Yorkshire
How much does a car diagnostic test cost?
+
We offer an honest, transparent diagnostic service. Ask when you book and we'll give you the cost upfront — before any repair work is agreed.
Why is my engine warning light on?
+
It can be something minor like a loose fuel cap or a faulty sensor, or something more significant. We read the code to find out what's actually triggering it rather than guessing.
Can you fix the problem after reading the code?
+
Yes — in most cases we can carry out the repair in-house, so you don't need to take the fault elsewhere. You get a clear quote after diagnosis.
Is it safe to keep driving with the light on?
+
It depends. A flashing light or a loss of power should be checked promptly; a solid light can often wait a few days. If in doubt, call us and we'll advise.
