Whether your Hyundai needs routine maintenance, an oil and filter change, diagnostic testing or investigation of a dashboard warning, our experienced technicians can help.
Regular servicing can help:
1. Maintain your Hyundai’s reliability
2. Identify wear before it becomes a larger problem
3. Support engine performance and fuel efficiency
4. Reduce the risk of unexpected breakdowns
5. Keep important safety components properly checked
6. Provide a clear record of vehicle maintenance
Before completing any work, we use your registration details to identify the correct engine, transmission, parts, fluids and servicing requirements.
Our independent garage is located on Sloper Road near Cardiff City Stadium. We welcome Hyundai owners from Leckwith, Canton, Grangetown, Riverside, Ely, Fairwater and communities throughout Cardiff and South Wales.

What Is Included in a Hyundai Service?
Your Hyundai’s servicing requirements depend on its model, engine, age, mileage and maintenance history. We check what is due rather than applying the same service package to every Hyundai.

3. Cabin or pollen filter
4. Fuel filter where applicable
5. Spark plugs on applicable petrol engines
6. Brake fluid
7. Engine coolant
8. Hybrid-system coolant where applicable
9. Brake pads and discs
10. Tyres and tyre pressures
11. Steering and suspension components
12. Exterior lights

After inspecting your Hyundai, we will explain any problems we find. We will not complete additional repairs without discussing the work and cost with you first.

Hyundai dashboard warning lights
A warning light means the vehicle has detected a problem, but it does not always identify the component that needs replacing.
A1 Diagnostics can investigate warnings involving:
1. Engine management
2. Hybrid or electric systems
3. ABS and brakes
4. Airbags
5. Battery and charging
6. DPF or AdBlue systems
7. Tyre-pressure monitoring
8. Automatic transmission
9. Key and immobiliser system
10. Driver-assistance systems
Our technicians combine diagnostic equipment with further testing to identify the underlying cause. This helps reduce the risk of replacing parts unnecessarily.
Hyundai automatic and dual-clutch gearboxes
Hyundai has used conventional automatic, continuously variable and dual-clutch transmissions across its vehicle range.
Possible signs of a gearbox problem include:
1. Juddering
2. Hesitation
3. Delayed drive engagement
4. Harsh or irregular gear changes
5. Unusual gearbox noise
6. Transmission warning light
7. Reduced performance
8. Fluid leaks
The correct fluid and maintenance procedure depend on the exact transmission fitted. A fluid service will not repair every clutch, electrical, hydraulic or internal mechanical fault.
Hyundai hybrid and electric vehicles
Hybrid and electric Hyundai vehicles still require regular inspections of components such as:
1. Brakes
2. Tyres
3. Steering and suspension
4. Cooling systems
5. Air conditioning
6. Windscreen wipers and washers
7. Exterior lighting
8. 12-volt battery
