Re: max care unlimited / unlimited with '14 diesel?
Just google "EGR and DPF problems" and you will see the havok they cause. Most people get them blank and retune the car's ECU to bypass them.
From the looks of it, this jeep comes with an EGR, DPS, Urea cycle with injectors, and swirl flaps on the intake manifold.
Usually the EGR is the first to go, clogging up and sending more soot into the intake manifold. This will lock up the swirl flaps and eventually cause it to read a fault in the engine. Since compression and fuel air mixture will be crap, the DPF will clog up and your car will go into limp mode, until you shut it off and restart it. It will drive ok a few miles and it will happen again. Many of these things go UNNOTICED if you drive short distances to work everyday...eventually all this pressure will cause a nice split down your exhaust manifold and take the turbo along with it.
Its a viscous cycle.
Ive owned 2 diesel passenger cars both after 2005 model year and both had the problems. One was a 2006 1.9 CDTI Opel which needed a new intake, exhaust and EGR, the other was a 2009 3.0 Audi A6 which needed a new DPF.
This was all when I lived in europe for 6 years, Luckily, the mechanics there are all to aware of these diesel problems and find used parts relatively cheap.
Needless to say, I will never buy another diesel again. If you want fuel efficiency, take the small 4 cyl turbo in a car. If you need power, take the v8.
Once I did a 400 dollar ECU tune on my OPEL completely blanking the EGR and DPF, it drove very well and never had another problem.
