- Medium severityFrequency: Very frequentOM642Emissions defeat device (AdBlue/EGR) and software update campaignGermany's KBA found indications of emissions manipulation in cars with the OM642 engine (alongside the OM651): AdBlue dosing and the EGR changed between the test bench and the road. Mercedes-Benz denied it, but in 2018 it recalled hundreds of thousands of diesels in Europe.
In Grand Cherokee WK
- Medium severityFrequency: Common1.6 and 2.0 MultiJet IIEGR valve blocked by soot in urban useYes: the EGR valve builds up soot with urban use and short journeys, which causes loss of power and turns on the engine fault warning light. It is one of the most frequently cited faults of this engine in both the Jeep Renegade and the Fiat Doblò.Repair (garage): €200–€500
In Compass MP and Renegade
- Medium severityFrequency: Occasional2.2 JTDm Multijet IIClogged 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.
In Wrangler JL
- Low severityFrequency: OccasionalVM Motori 2.8 and 3.0 CRDEGR valve and intake clogged with sootWith short journeys, the EGR valve and intake of the 2.8 and 3.0 CRD accumulate sticky deposits that cause jerking, black smoke and uneven running.
