If you’re actively looking for a car diagnostics test in Cardiff, it’s more than likely you’re experiencing some type of issue with your vehicle. Whether a warning light has appeared on your dashboard or whether you’ve noticed a difference in how your car feels or performs, these are signs that should not be ignored.
Our car diagnostic testing service regularly identifies the root cause behind common vehicle issues, such as:
Dashboard lights flashing
ABS warning light faults
Poor fuel economy
Airbag system errors
Electrical system failures
Battery drain or charging faults
Misfires and rough idling
When you bring your car to Lawfix Automotive, we thoroughly diagnose the fault and break down the root cause of your issues in plain English. No work is undertaken without your consent. Our car diagnostic check typically includes the following types of checks:
We use specialist diagnostic equipment to check for stored fault codes. These codes help us identify where the fault may be coming from.
If a warning light has come on, we can check what has triggered it. This includes engine management, ABS, airbag, battery, DPF, and other dashboard warning lights.
Many vehicle faults we see are linked to sensors, wiring, air leaks, fuel issues, or engine running problems. No matter the root cause, we can narrow down what is likely causing the issue.
Some warning lights and starting problems are caused by weak batteries, alternator faults, or charging issues. If there is a warning light appearing on your dash, this makes it easier for us to identify the root cause of the issue.
Some faults are caused by small leaks that are hard to spot by eye. If we suspect an air, boost, vacuum, or intake leak, we can carry out further checks to help identify the source of the problem.
Smoke testing can be useful when a car has poor running, loss of power, rough idle, hissing noises, turbo issues, or warning lights related to airflow and emissions. It helps us trace leaks in pipes, hoses, joints, and intake areas that may not be easy to see during a normal visual check.
We can also check for signs of fluid leaks, such as coolant leaks, oil leaks, and other visible leaks around the engine bay where needed.
Some faults only show when the car is moving. If needed, we may road-test the car to identify the problem and check how it behaves under normal driving conditions.
Not every fault manifests itself as a sudden breakdown. Most of the time, your car will give you subtle signs that something’s gone wrong under the hood. The issue is that most people ignore these signs and hope they go away.
In our experience, ignoring these signs only makes the outcome worse when you inevitably have to face the issue. Booking a car diagnostics test right away can save you a lot of frustration and constant repair costs down the line.
Here are just a few reliable warning indicators that you need an urgent diagnostic test:
Dashboard warning lights are typically the most common indication that you need to book a diagnostic test. Whether the engine, ABS, emissions, or battery light flashes, these are strong signs that it’s time to book a diagnostic car test.
Even if your car appears to be performing as it usually does, the onboard system is telling you something’s going wrong within your vehicle. We highly advise against clearing the lights without actually diagnosing the issue. Proper car diagnostic testing ensures the fault is correctly identified and resolved.
Sometimes, when there’s a fault with your vehicle, you’ll notice a decrease in performance. This typically manifests itself as:
Reduced power
Increased fuel consumption
Unusual noises
Difficulty starting the vehicle
Difficulty shifting gears
If you are experiencing any of these issues, be sure to give us a ring to book a quick diagnostic check to identify the root cause.
When you bring your car to Lawfix Automotive for a diagnostic test, we follow a tried-and-tested process to accurately diagnose the issues you are experiencing. Here’s what you can expect:
First things first, we’ll have a quick call to chat about the issues you are experiencing. This allows us to ensure that it is, in fact, a diagnostic check you require. If you don’t require the service or we think it’s a separate service you need, we’ll advise you.
Should you need car diagnostic testing, we’ll book a date and perform a comprehensive diagnostic across all applicable control units. We leave no stone unturned and ensure the work isn’t finished until we have found the root cause for you.
Once we have confirmed the underlying factors causing your issue, we’ll provide you with a clear breakdown of the problem and advise you on the next ebay steps. If repair work is required, we won’t undertake any work until we have confirmed a price with you, so you’re not left with any nasty, unexpected bills when you come to collect your vehicle.
Although diagnostic tests always feel like an inconvenience and unnecessary expense, in the long term, they’re usually the cheapest option on the table. Here’s why:
Without a proper diagnostic test, problems can be misdiagnosed and incorrect repair work undertaken. For example, a sensor code may actually be caused by wiring damage, vacuum leaks, or even software issues. By getting an advanced diagnostic test, you can be sure the work being undertaken is the right fix and that you won’t need to return to the garage for further work.
What appear to be minor surface faults can actually cause major problems if left untreated. An undiagnosed misfire, for instance, can damage catalytic converters. A battery charging fault can affect multiple electronic modules. Getting a professional car diagnostic shortly after identifying an issue completely removes the risk of an inexpensive issue becoming a big bill down the line.
Vehicles with undiagnosed faults tend to consume more fuel, reducing your fuel efficiency and increasing your monthly fuel costs. A proper diagnosis identifies the issue so it can be resolved, restoring your fuel efficiency to where it should be.
Breakdowns are annoying and expensive. Oftentimes, these breakdowns are caused by undiagnosed issues within your vehicle. A diagnostic specialist helps you get ahead of the curve and ensures you’re not the one stuck on the side of the motorway on a cold, windy British day!
