Parts for the Mazda 2 MZ-CD

Known issues

MAZDA 2;DEMIO MZ-CD owners should be aware of some common issues that can arise, particularly between 80,000 and 150,000 kilometers:
• Diesel Injector Problems: Diesel injectors are prone to coking and eventual failure. Regular fuel additives designed to clean injectors might help prolong their life.
• DPF Clogging: The Diesel Particulate Filter (DPF) can become clogged, especially if the vehicle is primarily used for short trips. Consider occasional longer drives to allow the DPF to regenerate.
• Turbocharger Concerns: Turbocharger failure can occur, often due to oil starvation. Ensure regular oil changes with the correct specification oil and check for any unusual noises or loss of power.

WOF tips

When preparing for a Warrant of Fitness (WOF) inspection, keep the following points in mind:
• Diesel Smoke: Be aware that excessive diesel smoke, particularly during acceleration, is a common WOF failure point.
• Oil Leaks: Inspect the engine for any oil leaks, especially around the turbocharger and injectors.
• Brake Lines: Examine brake lines for corrosion, with a focus on areas near fittings, as corrosion can lead to leaks and WOF failure.
