Parts for the Mazda CX-5 D

Known issues

CX-5 D owners should be aware of some common issues that may arise, typically between 80,000 and 150,000 km:
• Carbon Buildup: The intake manifold is prone to carbon buildup, which can affect engine performance. Periodic cleaning or intake manifold replacement might be required.
• DPF Problems: Diesel Particulate Filter (DPF) regeneration issues can occur, particularly with frequent short trips that don't allow the DPF to reach its optimal cleaning temperature. Consider longer drives periodically or DPF cleaning treatments.
• EGR Valve Failure: EGR (Exhaust Gas Recirculation) valve failure is another known issue. A faulty valve can lead to poor engine performance and increased emissions.

WOF tips

When preparing your CX-5 D for its Warrant of Fitness (WoF), be mindful of these common check points:
• Tyre Condition: Pay close attention to tyre condition and watch for uneven wear patterns, which could indicate alignment issues.
• Brake Pad Thickness: Ensure brake pad thickness meets the required safety standards.
• Diesel Particulate Filter (DPF): The function of the DPF will be assessed to ensure it's operating correctly.

About the Mazda CX-5 D

The CX-5 diesel has proven a practical and economical option for many Kiwi families and commuters. To keep your CX-5 D running smoothly, consider these maintenance points:
• Cooling System: Regular checks of the radiator cap and coolant are essential. Consider the long-term condition of components that manage engine temperature, such as the thermostat and water pump.
• Drivetrain: Routine servicing of the automatic transmission, including replacing the automatic transmission filter and fluid, helps ensure smooth shifting and reliable performance.
• Braking System: Inspecting the front disc brake rotors regularly contributes to safe and effective braking.
• Engine Management: Monitor the condition of sensors like the crank angle sensor and pressure switch for the EGR valve. These components play a vital role in engine performance and emissions control. Replacing the EGR valve preventatively may be a good option.
• Suspension: Consider replacing the strut boot kit on the rear shock absorbers to protect them from damage. Also, camber bolt kits on the front suspension may require replacement with age.
• Wheel Hubs/Bearings: Inspect rear wheel hub/bearing condition, including related wheel bearing kits.
• Other: Cylinder head bolts should be checked or replaced, as advised by the vehicle's service schedule.

Addressing these areas proactively can help prevent more costly repairs down the road. When replacing parts, consider the suitability of various aftermarket options to optimize value and performance.
