And if so, how hard is it, garage jobbie or monkey on the drive way with a hammer?

DPF is just the exhaust. If you can change an exhaust, you can change the DPF.

There are just a couple of pipes screwed into it from and to the differential pressure sensor. (Y)

Ah, is it not a seperate component then, was thinking it may be like a fuel filter?

It's just the centre section of the exhaust the DPF is integratedinto it. It runs from the bottom of the downpipe from the turbo (I think) to the backbox (I know)

I am sure you need to tell the car with tech2 that the dpf has been changed. The consequences of not doing so, I'm not sure, but there is definitely an option in the tech2 to do this.

yep you can remove, we do it at my garage and ive seen a million. The correct way is to have it laser torched out compeltely, and then either a remap or factory program to let car know the dpf is removed. ive seen people come in who have smashed their own dpf out, its basically like a honeycomb nest, and then just drive around and not propelry removed all the small pieces smashed off and they wonder why their cars run terrible and smoke to hell.

so id suggest take it somewhere to have it cleanely and completely removed or replaced and then the appropiate software alterations done

Or you can chop the exhaust and weld or clamp in a new section then you can refit the dpf for selling

mikie it wont necesarily fail an mot. the new MOT regs do include a provision that any original emissions kit must remain on the car, ie you cannot remove cats/DPFs etc. However, this is a visual test and so removing the internals and refitting the empty DPF box would generally be a pass, most cars will then pass a smoke test even without the DPF in place.

I removed it as I was in a rush and didn't have time to expand on it :)

I just put that it wouldn't pass MOT's but I wanted to say what you said. It's a visual inpsection, so if the DPF has been removed then it's a fail, if the internals have been hollowed out, it'll probably pass.

Another reason I removed it because a thought came to me that it had been discussed before and the new regs apply to petrols not diesels but I couldn't find that so didn't want to make a sweeping statement that was false (Y)

Cool thanks for your help guys.

Currently I've put DPF cleaner through the car which seems to have helped, the car in on 65k adn never been looked at so no doubt the filter is pretty grotty by now.

The stuff we shoved in is expensive stuff too, £17 for a tin no bigger than a coke can, but will be adding redex style cleaner (for the DPF) as well to help clean more.

Have also got a garage local that will do a diagnostic check for FREE! Slightly better than the £90 VX wanted!

The only time I ever had a problem with the DPF was at 10K when I had an EGR problem and was told it was OK to run around on until my allocated booking time at the local VX garage. Unfortunately if there are any faults stored relating to the intake, it stops any regeneration taking place. So I ran around and the DPF was blocked solid. So much so that the engine would start for a second then stop because the exhaust gasses had nowhere to go. It was replaced under warranty but I've had no DPF problems since. Motorway miles is what I do mostly so never a problem.
