Vehicle Diagnostics in Wrexham
Dealer level diagnostics in Wrexham, at your home, your work or on the Industrial Estate.
A warning light does not tell you much on its own. We bring dealer level diagnostic equipment to you in Wrexham, read what the car is actually reporting across all its modules, and explain what it means in plain terms before anyone spends money on parts.
Why a code read on its own is not a diagnosis
A cheap code reader gives you a number and a generic description, and that description names a circuit, not a culprit. The same code can be a failed sensor, a wiring fault, a connector that has taken water, or a genuine mechanical problem somewhere else that the sensor is honestly reporting. We read live data alongside the codes, check the freeze frame from when the fault was stored, and where it helps, run the vehicle to see the fault happen rather than guessing at it afterwards.

What the equipment actually reaches
We use dealer level equipment rather than a basic code reader, which means manufacturer specific codes across all the modules, not just the generic engine ones. Alongside the stored codes we look at live data and at the freeze frame the car saved at the moment the fault occurred, because that tells us the conditions it happened in. Then we explain what it means in plain terms and tell you whether it needs repair, further investigation, or simply clearing.
Before you book the car into a garage
It is worth knowing what is wrong before you agree to work. Plenty of people come to us after being quoted for a part on the strength of a single code, and sometimes that part is right, but not always. Because we come to you in Wrexham there is no recovery to arrange and no waiting on a courtesy car, and if the answer is that you need a mechanical repair we will say so rather than sell you something else.

Frequently asked questions
My car is at home in Wrexham and not driveable. Can you still come?
Usually yes, as long as it is somewhere we can work safely and get access to the OBD port. Being able to read a car where it sits is one of the main reasons a mobile service is useful. Tell us what it is doing when you get in touch.
Can you come to a unit on Wrexham Industrial Estate during the working day?
Yes. Fault finding on site is often easier than sending a vehicle away, particularly for a van that is needed the same week. Let us know where on the estate you are and what the vehicle is doing.
Do you charge for the diagnostic if I then have the work done?
Talk to us about it when you book rather than assuming either way. What we will not do is carry out work before we know what the fault actually is.
What does a vehicle diagnostic check involve?
We connect to your vehicle's ECU and read stored fault codes and live data, along with the freeze frame saved when the fault occurred. We then explain what the codes mean and advise on whether the issue needs repair, clearing, or further investigation.
My engine management light is on. Can you help?
Yes. We read the codes that triggered the light and, more importantly, work out whether they point at the cause or at a consequence of something else. Get in touch and we will arrange a visit.
If something has come up on the dash and you are in or around Wrexham, get in touch and we will take a proper look.
