2.2 JTDm Multijet II engine: faults and reliability

• 2.2 JTDm Euro 6 (136-210 hp, 2016-2019)

  2016–2019 · 136–210 hp · 55275156

  With caution

  The engine has a good reputation, but these years accumulate two campaigns: the fuel filter gasket (2018 diesel Giulia, Italy) and the alternator cable next to the exhaust gas recirculation pipe (2017-2018 diesel Stelvio), as well as leaks and oil consumption in the testimonials. Buy with the campaigns done and the oil history in hand.^{[1][3][4][5][6]}

• 2.2 JTDm Euro 6d with AdBlue (136-210 hp, 2019 onwards)

  since 2019 · 136–210 hp

  With caution

  It is the same engine with AdBlue added and we have found no faults specific to this version: a 210 hp Stelvio completed 100,000 km without faults, although with a fluid loss around the crankshaft, deposits on the intake valves and high AdBlue consumption. Can be bought if you check the codes of the AdBlue system and particulate filter and the oil level.^[2]

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. 1High severityFrequency: OccasionalFuelDiesel leak from the fuel filter gasketAlfa Romeo recalled 3,873 2018 Giulia with the 2.2 diesel over a faulty fuel filter gasket that caused diesel leaks (according to Alvolante). The source gives no date or reference for the campaign and cites no real failures.
2. 2High severityFrequency: OccasionalElectronicsAlternator cable touching the exhaust gas recirculation pipe (fire risk)An Alfa Romeo campaign covers diesel Stelvio built between 18 January 2017 and 18 September 2018: an alternator cable may rub against the exhaust gas recirculation pipe and cause a short circuit, with a fire risk in the worst case.
3. 3Medium severityFrequency: OccasionalLubricationEngine oil leaksLeaks and oil consumption are the most cited items in testimonials for the 2.2 diesel: 12 of 84 in the Stelvio and 9 of 68 in the Giulia. A 100,000 km test detected a fluid loss around the crankshaft; Alfa Romeo replied that the measured wear was low.
4. 4Medium severityFrequency: OccasionalEmissions controlClogged particulate filter (DPF) and EGR valve with depositsThe particulate filter and EGR valve of the 2.2 diesel are listed among its weak points in a German guide; the testimonials record excessive regenerations and replaced particulate sensors. Alfa Romeo attributes the intake valve deposits to the operation of the EGR.
