Greetings,
Can anyone tell me how to identify a DPF on a 1.5 Lt. K9K engine. I am trying to find out if my NV 200 has a DPF. I E mailed Nissan but their response was, contact your main dealer.

Without physically looking under the van it could be tricky. (under the van there closer to the engine there should be the catalytic converter and a larger looking silencer - usually the dpf has smaller pipes running in and out.

Other than that do you know if your van is euro 4 or euro 5, I believe the euro 5 are all dpf equipped hence why they passed the emission regulation. (got me thinking now does it say euro 5 on a log book?)

Or another way is to find out how many grams of CO2 your vehicle emits surely the dpf will be lower?

Just my 2ps worth and I am sure someone will correct us soon!

I haven't looked at my DPF yet, but when this awful weather improves I might crawl under my van with a camera and take some pics. In the mean time, a google image search for nissan diesel particulate filter should give you an idea of what you are looking for- bulge in the exhaust pipe, fairly close to the engine, with small-bore pipes coming out of it for pressure sensor etc.

Not sure if CO2 figure would reveal much. I thought the DPF was a mechanical filter designed to trap solid particals. CO2, being a gas, would pass straight though? (I'm no expert though, and would gladly be corrected on this)

Hi Lads and a happy new year to you all, thanks for your replies. When I serviced it recently I noticed a large box in the exhaust very close to the manifold. It is about twice the diameter of the exhaust pipe but I failed to notice if any pipes or wires were attached. It could be a catalytic converter. I will have another look and let you know.
