Hi guys, i've just purchased my first Jeep Grand Cherokee... what a motor it is..very impressed so far,but i have a question on the diesel particulate filter...?? Do i have one ....its a 2005 55'plate 3.0 CRD Limited first registered in dec 2005.

Thanks in advance....

I believe the dpf came out in 2007, at least thats the case for north america.

Hi suzieque,
yes i've read that also but the diesel has been with the uk since april 2005, and i think it has the same engine so ......still un-decided, ok where could i look on the car to find the particulate filter itself and what exactly would i be looking for....???

Thanks for your reply...

Merlintec can verify this...but I am 95% sure the DPF is a North America feature because of EPA2007 emissions

hi scootr,
You could well be rite, i've not found anything in my handbook that states i've got one......how can i send merlintec this question.....???

Instead of the guessing game, get under there and take a look.

[karlandbev]

Thanks for that toycarrier......but what exactly should i be looking for...ie...where is it and what would it look like....does it look similar to the catalyst......?????

here are some photos of where the dpf is located on my 2008 WK 3.0L CRD.

I tried to circle the dpf in the photo, still hard to see it because it sits low. also keep in mind that the photo is from a left hand drive jeep.

The circled thing above is the catalyst (?).
The dpf is located below the passenger side seat. you can see the two fuel lines that feed it.

This is the DPF but the two lines are actually for a differential pressure sensor so it can measure the difference in pressure across the filter to estimate how full it is and when to burn it off. It is a passive DPF and fuel is not injected into the exhaust past the engine. The ECM creates high exhaust temps through changing a bunch of variables to burn off the soot.

As for the first picture it is a pre-catalyst, there is also the main catalyst further in line between the DPF and pre-cat.

Now thats what i was after.......Will check first thing in the morning....thanks to all.....

Hi
Correct they are pressure line the go to the pressure sensor you can see in the first picture.
Karl our GC don't have DPF for some reason, only the 300c and Commander (with the same engine) does.

Merlin

I'm not sure this statement is true, or maybe its just not true with Canadian delivered CRDs.
