What changes compared with the 2003 Mazda 2
The same engines and the same documented faults as in 2003.
1.4 HDi engine in the 2004 Mazda 2
Names: 1.4 CD (MZ-CD)
- With caution
1.4 HDi/TDCi 54/68/70 8V (DV4TD, 2001-2009)
54–70 hp · DV4TD, 8HT, 8HX, 8HZ
It shares the injector fragility of the rest of the family, documented in both the 68 and 70 hp versions, along with occasional turbo and EGR valve failures. It is worth buying with a maintenance history and no noticeable diesel leaks.[3][4]
Faults that affect 2004 cars
- Medium severityFrequency: Very frequentInjectionInjectors that lose their seal and let diesel escapeThe most cited weak point of the 1.4 HDi is its injectors: over time they can lose their seal and let diesel escape, which is usually noticed as a smell of diesel in the car. It appears in the two most common outputs (68 and 70 hp) and in both cases it is identified as the engine's main weakness.
- High severityFrequency: OccasionalTimingTiming belt and water pumpThe 1.4 HDi uses a timing belt (with an additional short chain on the 16-valve version), and Fiches-Auto documents some of its failures, along with the water pump, at around 100,000 km. We have not found the manufacturer's official change interval in a reliable source.
- Medium severityFrequency: OccasionalTurboPremature turbo wear from poor lubricationThe BorgWarner KP35 turbo of the 8-valve version can wear out early when the oil degrades and forms carbon deposits, reducing its lubrication. It is a minority but recurring fault: it appears in just over 9% of the reports collected for the 68 hp version.
- Medium severityFrequency: OccasionalEmissions controlEGR valve clogged with carbonThe EGR valve, which recirculates part of the exhaust gases to reduce emissions, can seize or clog up with the carbon those gases carry. It appears in a noticeable minority of the reports collected for the 68 hp version.
- Medium severityFrequency: RareTimingCrankshaft damper pulley wearThe crankshaft pulley incorporates a rubber ring that dampens engine vibrations and that can lose grip or crack over time. We have found only one specific report of this fault (a Peugeot 206 at around 250,000 km), so we do not consider it a widespread fault.
Faults outside the engine in the 2004 Mazda 2
- Medium severityFrequency: OccasionalSuspensionFront and rear suspension spring failuresAccording to the Gebrauchtwagenberater, ADAC's breakdown statistics place the front and rear suspension springs among the Mazda 2 DY's weak points, along with the spark plugs. The source does not detail the type of failure or the mileage.
- Medium severityFrequency: OccasionalGearbox and clutchClutch wear and hard-to-engage gears on the 1.4 MZ-CD dieselOn the Mazda 2 DY 1.4 MZ-CD diesel, the Gebrauchtwagenberater notes that the clutch fairly often forces unplanned visits to the garage and that the gears are hard to engage. The source gives no mileage or cost.
- Low severityFrequency: OccasionalSuspensionPremature wear of the rear shock absorbersThe Gebrauchtwagenberater notes that in the German roadworthiness inspection (TÜV) the Mazda 2 DY's rear shock absorbers are flagged from time to time and that, in isolated cases, they had to be replaced at only 60,000 km. No manufacturer campaign is recorded.
