A1 Diagnostics provides professional Ford servicing, diagnostics and repairs from our independent garage in Cardiff. From routine oil and filter changes to EcoBoost engine maintenance, wet-belt work, PowerShift diagnostics and suitable Ford van servicing, our technicians can help maintain your vehicle’s performance, reliability and safety.
Ford vehicles use a wide range of petrol, diesel, hybrid and electric powertrains. Servicing should therefore follow the requirements of the precise model and engine rather than a generic schedule.
Before completing any work, we identify the vehicle using its registration and check the applicable maintenance requirements, oil specification and replacement parts.
Our workshop is located on Sloper Road near Cardiff City Stadium, serving Ford owners from Leckwith, Canton, Grangetown, Riverside, Ely, Fairwater and communities throughout Cardiff and South Wales.
The correct interval depends on the model, engine, age, mileage and operating conditions. The applicable maintenance schedule should be checked using the vehicle’s registration and engine information.
A service may include engine oil and filter replacement, additional filters, fluid checks, safety inspections, diagnostic scanning and resetting the service indicator. The precise work depends on what is due.
A suitably equipped independent garage can complete many Ford servicing and repair procedures. The applicable schedule should be followed and suitable parts and correctly specified fluids used. Check the conditions of any manufacturer or third-party warranty.
Certain Ford petrol and diesel engines use oil-immersed belts, but the design varies by engine and year. The registration and engine code should be checked rather than assuming every EcoBoost or EcoBlue engine has the same timing system.
The applicable replacement requirement depends on the exact engine, vehicle age, mileage and current technical schedule. Oil condition and service history should also be considered.
Possible signs include belt deterioration, low oil pressure, debris within the lubrication system, unusual noises or timing-related faults. A deteriorating belt may not always produce an obvious warning.
A1 Diagnostics can service supported PowerShift transmissions. The required fluid, filter and procedure depend on the exact gearbox. Existing gearbox problems should be diagnosed rather than assuming fluid replacement will resolve them.
Yes. A1 Diagnostics can investigate many engine, transmission, ABS, airbag, battery, emissions and driver-assistance warnings. Further testing may be required after the stored fault codes are read.
A1 Diagnostics can service and repair many suitable Ford Transit and Transit-based light commercial vehicles. Provide the registration and vehicle details so workshop compatibility can be confirmed.
The cost depends on the model, engine and maintenance items due. Provide the registration number, mileage and service information so A1 Diagnostics can prepare an accurate quotation.

The work included in a Ford service depends on the model, engine, age, mileage, maintenance schedule and previous servicing history. A1 Diagnostics follows the relevant vehicle information rather than applying one checklist to every Ford.
Depending on what is due, servicing may include:
1. Engine oil and oil-filter replacement
2. Air-filter inspection or replacement
3. Cabin or pollen-filter replacement
4. Fuel-filter replacement where applicable
5. Spark-plug replacement on applicable petrol engines
6. Brake-fluid replacement
7. Coolant checks
8. Brake pad and disc inspection
9. Tyre condition and pressure checks
10. Steering and suspension inspection
11. Exterior lighting checks
12. Drive-belt inspection
13. Battery and charging-system checks
14. Diagnostic system scan
15. Inspection for visible fluid leaks
16. Service-indicator reset
17. Road test where appropriate
The correct engine oil should be selected according to the precise Ford engine and required manufacturer specification. We ensure we have the correct quality oil needed for your vehicle.
Ford vehicles may display additional maintenance requirements or workshop codes relating to:
1. Timing belt or wet belt
2. Timing chain
3. Auxiliary drive belt
4. Manual gearbox
5. Automatic or PowerShift transmission
6. Spark plugs
7. Fuel filter
8. Brake fluid
9. Coolant
10. Four-wheel-drive system
11. Air-conditioning system
12. Hybrid or electric cooling systems

Certain Ford engines use a timing belt that operates within the engine oil. This is commonly called a wet belt or belt-in-oil system.
The exact belt arrangement and replacement requirements vary by engine. Some engines can also contain a separate oil-pump belt, so the complete engine specification must be checked.
Potential signs of deterioration or a related problem can include:
1. Low oil-pressure warning
2. Visible belt deterioration where inspection is possible
3. Belt material or debris within the lubrication system
4. Unusual engine noise
5. Engine warning light
6. Poor engine performance
7. Oil-pickup or lubrication restrictions
8. Timing-related diagnostic trouble codes
A wet belt may deteriorate without producing an obvious warning symptom. A diagnostic will determine the exact problem and work needing to be carried out.
Ford has used different PowerShift transmissions with differing clutch systems, fluids, filters and maintenance requirements.
A PowerShift service may involve:
1. Identifying the exact transmission
2. Reading stored gearbox faults
3. Inspecting for fluid leaks
4. Draining the applicable transmission fluid
5. Replacing the filter where specified
6. Refilling with the correct fluid
7. Completing diagnostic checks
8. Performing adaptations where required
Fluid servicing will not repair every PowerShift problem. Clutch, mechatronic, electrical or internal mechanical faults may require separate diagnosis and repair.

We can service your Ford vehicle. Get in touch if you have any queries we are happy to help.
