1.6 TDI common rail EA189 (2009-2015) engine: faults and reliability

Volkswagen 1.6 TDI (EA189 and EA288) version

With caution

The dieselgate scandal affects the whole series: check that the update (software and air flow stabiliser) has been done and that there are no symptoms of EGR, particulate filter, turbo or water pump problems.[1][2]

Faults of the CAYC engine

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

  1. 1Medium severityFrequency: Very frequentEmissions controlManipulated emissions software (dieselgate) and air flow stabiliserThe 1.6 TDI EA189 engines (2009-2015, 75-105 hp) carried software that reduced exhaust gas recirculation (EGR) outside homologation tests. Unlike the 2.0 TDI, Volkswagen corrects this engine with the software update plus the fitting of an air flow stabiliser.Repair: €0
  2. 2High severityFrequency: OccasionalTimingTiming belt and water pumpThe 1.6 TDI drives its timing with a toothed belt. It is common for the water pump to be changed together with the kit: if the pump seizes first, it can drag the belt with it, with a risk of breakage and serious cylinder head damage.Repair (garage): €400–€1,500
  3. 3High severityFrequency: OccasionalTurboVariable-geometry turbo seized or with playThe variable-geometry turbo on the 1.6 TDI EA189 can seize because of carbon deposits or wear on the shaft. The engine loses power, whistles or emits bluish smoke, and replacing the turbo costs around €1,000 if there is no additional damage.Repair (garage): €1,000
  4. 4Medium severityFrequency: CommonEmissions controlEGR valve clogged with carbon depositsThe EGR valve accumulates carbon deposits, especially on short urban trips, until it seizes and no longer seals or opens precisely. The engine loses power and jerks; cleaning the valve costs considerably less than replacing it.Repair (garage): €100–€1,000
  5. 5Medium severityFrequency: CommonEmissions controlClogged particulate filter (DPF)In urban use and on short trips, the particulate filter does not complete regeneration and becomes saturated with soot. The DPF warning light comes on and, if ignored, the car may enter limp mode with a loss of power.Repair (garage): €200–€3,000
