1.3 Multijet 8v (69-105 hp, 2003-2009) engine: faults and reliability

Fiat 1.3 Multijet / JTD (SDE) version

With caution

It is the generation that has been on the road longest and the one with the most documented cases of stretched timing chains and failed tensioners. It is only worth considering with an oil change history and, ideally, with the chain already inspected or replaced.[1][2][3]

Engine codes of this version: Z13DT.

Faults of the Z13DT engine

The documented engine faults that affect this version and its years, from most to least important.

  1. 1Critical severityFrequency: CommonTimingTiming chain stretch and tensioner failureYes: the timing chain's hydraulic tensioner can lose pressure and let the chain slacken; if it skips teeth or breaks, it can destroy the engine. It is a documented problem on Fiat, Opel, Suzuki and Ford cars with this engine, mainly linked to long oil change intervals.Repair (garage): €350–€550Appears at around 70,000 km
  2. 2High severityFrequency: OccasionalTurboSeized variable-geometry turboOn versions with a variable-geometry turbo, the vanes can seize through soot build-up, especially on cars used in town for short journeys. The engine loses power gradually and may give off black smoke when accelerating.Repair (garage): €450–€700
  3. 3High severityFrequency: OccasionalInjectionInjector and high-pressure pump wear from contaminated fuelThe Bosch injectors and the high-pressure pump of the common rail system are sensitive to poor-quality fuel or fuel with condensed water. With contaminated diesel they can generate metal shavings that damage first the pump and then the injectors themselves.Repair (garage): €600–€1,200
  4. 4Medium severityFrequency: CommonEmissions controlEGR valve blocked by sootThe 1.3 Multijet's EGR valve easily accumulates soot on short urban journeys, causing an unstable idle, loss of power and the engine warning light. It is one of the most cited problems among owners of this engine.Repair (garage): €130–€400
