Particulate filter

I'm not sure if my 3.0 CRD has a particulate filter. Apparently it makes a difference to the oil grade. Where is it ? What does it look like externally ?
Thanks

yes your CRD came with a DPF if it was originally sold in the US. It's a bulge in the exhaust, just in front of the flex-hose section, about where the fron passenger seat is. It's after the catalytic converter.

"UK Spec" = something covering up the underbelly?

There's some cover but the exhaust is exposed.

More or less where the cat is shown on the posted photo mine has a large exhaust box/silencer. Forward of that , almost vertical between the underside of the manifold area and floor level at the rear of the engine compartment, is an item resembling the one in the photo. It doesn't have any fuel pipes going to it but there's a connector I reckon is the lambda near the top. It's all squinting and feeling because as you'll appreciate in that location it's a tight fit and surrounded by all sorts.

More to the point there's absolutely nothing resembling the photo underneath my car.

Don't forget our emission regs are or at least were quite a lot different to yours in the states.

In fact just looking at an enlarged version of that picture, mine starts where the joint can be just seen at the front on the pic as it heads up Into the engine compartment where that one ends.

I would've thought that the DPF would have to precede the catalytic converter...in order to prevent all the particulates from passing though (and clogging?) the converter...

No idea, hence the original question

However the uk spec cars are a mixed bunch, some have, some don't

Mind you, for those who have them, are they user removal clean or are they all the burn off type ?
