Anyone got any experience of doing this or have an idea of cost.
Had no end of trouble with mine, already spent nearly £400 trying to fix an "Engine Malfunction" message on my Convers+ screen - Probably going to cost another £400-£600 for the garage to get to the DPF, test all the individual components (vapouriser etc), figure out which bit is at fault and replace it. And if it's too blocked/fucked, then the whole DPF will need to be replaced anyway, which will cost anywhere up to £1700 if the various posts/info online are anything to go by.
But the bloke at the garage said that although they don't do it, you can remove the whole thing altogether and get the ECU remapped so that it gives the correct reading necessary to pass it's MOT - so I'm thinking about going down this route, but would all depend on cost and legality!
Any help/advice/info greatly appreciated!

Most diesel drivers have been sold a lie. We were told we were better for the environment with lower co2. We pay more for diesel than petrol and told to thrash the car up the motorway for 30 miles a week to keep the dpf working. Great for the environment that.
What sir you only use it to take the kids to school, go to the local shops, ferry the kids around, that is not what your car is designed for.... WTF.

Take the car for a good thrash up the motorway and stick in 4th gear, otherwise you don't get the filter hot enough to regenerate.
It needs to be somewhere around 600 c. whereas a normal exhaust is around 450 c.
If you still have a light on, get the filter changed, and get the fluid filled up (don't do this yourself the fluid is fucking evil).
For some idea when the lads in our workshop do a "forced regen" they literally hold their foot on the throttle for around 10mins until the filter is hot enough to regenerate.

Given the number of absolutely stinking diesels I cycle behind in London, especially older ones, DPFs are there because they are necessary. Official figures are that 4,000 people a year die prematurely in London because of air pollution. I think it's 29,000 across the UK. Diesels give off lots more NO2 and lots more particulates. If they are going to be driven in cities at all then they need DPFs at a minimum. Ideally the car tax needs to change so it charges for the amount of nitrous oxides and particulates as well as CO2.
The big problem in London is the taxis. There are not many private cars in central London on weekdays, but these days all the taxis are diesels. They need to put new emission standards in for taxis.
There are other issues as well:

Ultimately I think there needs to be a move away from diesel.
You will need to have the ecu modified so that it doesn't error when it sees the incorrect reading from the pressure senors at the DPF. If you're doing that you might as well get it remapped as well. You've just removed a massive blockage from the exhaust so you can run much more fuel and air now, which will give you more power and/or better fuel economy.
Oh and if you're remapping you might want to see if they can shut down the EGR so that the exhaust gasses stay in the exhaust and don't get shunted to the inlet, causing all sorts of wonderful crud getting deposited in the inlet manifold.
As for the legality of this, the new MOT regs. state that "if a DPF was fitted as standard, it must be present" but the DVLA haven't given the testing stations any info on which cars did have them fitted from the factory (they're still working on the list!). So it's down to the tester knowing that it should be there! Also if you have a thing that looks like a DPF but may or may not contain anything of substance, they cannot open it to check.
@joneve the DPF's are great if you do large mileage's, but quick, short run's around town really fucks them up.
If the garage hasn't changed the differential pressure sensor then that should be done. And I've never seen an individual part of a DPF filter that could be changed seperately....
The bit's outside (the diff pressure sensor, and the pipes to that) or the catalytic converter (which isn't the DPF).
