It ran great for a couple weeks then a shudder and surge on acceleration, then I guess it entered limp mode. I recently changed out my oil cooler seals and cleaned the intakes, flaps, everything. Since you have had this mod done for a year now, are you still happy with it? Any new issues that have been noticed? I thing I am going to give it a try. (It used to feel like, when I was feathering the brake to come to a smooth stop, that there was some other person suddenly applying EVEN MORE braking)Ĥ) Definitely does seem to be blowing more soot out the back (not visible generally, except inspecting the back bumper/body panels) Not great on mpg in that regard, but from a smoothness of applying brakes perspective, the feeling is quite nice now. I think that swirl motor was involved in full engine brake, but now that it is stuck open, it doesn't shut off completely. After this mod, that rough braking seems non-existent. I think this makes sense, as with the swirl motor open the whole time, the engine can't restrict enough air at low rpmsģ) Positive - my wife and I used to comment about how braking to a stop was rough. I would say ~1mpg in stop/start scenarios. So some observations after running this fix for awhile:ġ) Negative - Definitely seem to be rougher in the low RPM range.Ģ) Negative - Fuel mileage definitely seems to be less than previous. It was very similar except for the direction of the cabling in his ML vs my E320. I have performed this, and it is working flawlessly.Ĭoincidentally, this also seems to work on the M元20 cdi (or any other MB CDI motor with this swirl motor). By pulling the electrical connector off of the swirl motor, and plugging in a 4.7k resistor (1/4 watt) into pins 2 and 3, the ECU is fooled into thinking that the swirl motor is ok, and the CEL will go away after a few engine start/stop cycles. If you fix it, you will be in the same boat in another 50-100k miles.

In either case, P2015, or some other code relating to this motor is thrown (position issue, or other).Īfter reading a bunch of threads on the Jeep forums, as well as on the Chrysler forums that use the same tech, everyone's consensus seems to be that:Ĥ) invariably, this motor will get screwed up on all these cars with same motor even if you fix it. After time, the oil vapors/etc build up, and and either foul up the flaps, or the oil/gunk drips onto this swirl motor, and fries it. On the Bluetec, these invariably will get utterly screwed up because of the design of the motor with the PCV oil vapors breathing into the turbo inlet, thus intake manifold. P2015 is an issue with the swirl motor (or intake manifold flaps).
