Keep your Renault safe, reliable and ready for the road with professional servicing from A1 Diagnostics in Cardiff. We service and repair many popular Renault models, including the Clio, Captur, Mégane, Scenic, Kadjar, Austral and electric Renault models.
Whether your Renault requires routine maintenance, an oil and filter change, diagnostic testing or investigation of a dashboard warning, our experienced team can help.
Regular servicing can help:
1. Maintain your Renault’s reliability
2. Identify developing wear before it becomes more serious
3. Support engine performance and fuel efficiency
4. Reduce the risk of unexpected breakdowns
5. Keep brakes, tyres and suspension properly checked
6. Provide a clear record of vehicle maintenance
Before completing any work, we use your registration details to identify the correct engine, parts, fluids and servicing requirements.
Our independent garage is located on Sloper Road near Cardiff City Stadium. We welcome Renault owners from Leckwith, Canton, Grangetown, Riverside, Ely, Fairwater and communities throughout Cardiff and South Wales.
Renault Servicing Frequently Asked Questions
What Is Included in a Renault Service?
Your Renault’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 Renault.
Depending on the service required, our technicians may inspect or replace:
1. Engine oil and oil filter
2. Air filter
3. Cabin or pollen filter
4. Fuel filter where applicable
5. Spark plugs on applicable petrol engines
6. Brake fluid
7. Coolant level and condition
8. Brake pads and discs
9. Tyres and tyre pressures
10. Steering and suspension components
11. Exterior lights
12. Windscreen wipers and washers
13. Battery and charging system
14. Auxiliary drive belts
15. Visible fluid leaks
We can also complete a diagnostic system scan, reset the service indicator and road-test the vehicle where appropriate.
Carrying out the right maintenance for your Renault
Additional maintenance may be required for:
1. Timing belt
2. Timing chain
3. Auxiliary drive belt
4. Manual gearbox
5. Automatic or EDC transmission
6. Spark plugs
7. Fuel filter
8. Brake fluid
9. Coolant
10. Diesel particulate filter
11. AdBlue system
12. Air-conditioning system
13. Hybrid or electric cooling systems
Not every Renault uses the same engine or timing system. The correct maintenance should be checked using the vehicle registration and engine information.
After inspecting your Renault, we will explain any problems we find. We will not carry out additional repairs without discussing the work and cost with you first.

4. Battery and charging-system testing
5. Brake repairs

Renault dashboard warning lights
A dashboard warning means your Renault has detected a problem, but it does not always identify the part that requires replacement.
Contact A1 Diagnostics if your Renault displays:
1. Engine-management warning
2. ABS or brake warning
3. Airbag warning
4. Battery or charging warning
5. DPF warning
6. AdBlue or emissions warning
7. Gearbox warning
8. Key-card or immobiliser message
9. Tyre-pressure warning
10. Driver-assistance system warning
Our technicians use diagnostic equipment alongside further testing to identify the cause. This helps reduce the risk of replacing parts that are not responsible for the problem.
Renault automatic and EDC gearboxes
Renault vehicles have used several automatic and EDC dual-clutch transmissions. 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. Gearbox warning message
7. Reduced performance
The correct fluid, maintenance procedure and repair depend on the transmission fitted. A fluid change will not repair every clutch, electrical or internal gearbox fault, so diagnosis may be needed first.
Renault timing belts and timing chains
Renault has produced engines using timing belts and engines using timing chains. The vehicle should be identified before replacement is recommended.
Do not wait for obvious symptoms if a timing belt is due. A worn timing belt may fail without providing a clear warning. Ask A1 Diagnostics to check the applicable replacement information for your Renault.
