Known issues

Owners of the diesel Mazda 2/Demio have reported issues that can arise between 80,000 and 150,000 km. Keep an eye out for:
• Diesel Particulate Filter (DPF) problems: Clogging can lead to reduced performance and increased fuel consumption. Regular longer drives can help mitigate this.

WOF tips

When taking your Mazda 2/Demio MZR-CD for a Warrant of Fitness (WOF) inspection, be aware that inspectors often pay close attention to:
• Diesel injector seals: Leaks can lead to reduced engine efficiency and potential fire hazards.
• EGR valve clogging: This can affect emissions and engine performance.

Keeping the *steering rack* in good condition is essential for safe and responsive steering. When servicing, ensure the *wheel bearing kit/hub* is inspected.
