1.4 HDi engine (DV4): faults and reliability

• 1.4 HDi/TDCi 54/68/70 8V (DV4TD, 2001-2009)

  2001–2009 · 54–70 hp · DV4TD, 8HT, 8HX, 8HZ

  With caution

  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.^[2][3]

• 1.4 HDi 90/92 16V (DV4TED4, 2002-2009)

  2002–2009 · 90–92 hp · DV4TED4, 8HY, 8HV

  With caution

  We have not found published reliability statistics specific to this 16-valve version, but it shares the injector design of the rest of the family, so you should check for the same symptoms (smell of diesel, smoke) as on the 8-valve version.^[2][6]

Buy: No known serious faults, or they have already been corrected, in this version. With caution: Worth buying if something specific is verified: history, a replaced part or a completed campaign. Avoid: High risk of a serious fault that is hard to check for or prevent.

1. 1Medium severityVery frequentFrequency: 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.
2. 2High severityOccasionalFrequency: 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.
3. 3Medium severityOccasionalFrequency: 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.
4. 4Medium severityOccasionalFrequency: 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.
5. 5Medium severityRareFrequency: 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.

Technical data^[1][4][5][6]

1. 2001–2009

   1.4 HDi/TDCi 54/68/70 8V (DV4TD, 2001-2009)

   The original version of the family: 8-valve cylinder head and a single camshaft, no intercooler, with a fixed-geometry BorgWarner KP35 turbo. It is the most widely fitted variant, with outputs of 54, 68 or 70 hp depending on the injection pump setting and the brand (Peugeot, Citroën, Ford, Mazda, Toyota).^[4][5]

2. 2002–2009

   1.4 HDi 90/92 16V (DV4TED4, 2002-2009)

   High-output variant with a 16-valve cylinder head, a mixed timing drive of belt and a short chain, and a variable-geometry IHI RHF3V turbo with an intercooler, which raises output to 90-92 hp and torque to 200 N·m. It debuted in the first-generation Citroën C3.^[6]
