So.

I have two of these things.

They are the most tough durable cars I've ever owned despite the interiors being made of icing sugar

The first one is a 52 1.9JTD and at 199,448 miles it keeps plodding on averaging 55mpg or more depending on storm force head winds

When we first got it, it had a wobble. Lower suspension arms replaced and the longer drive shaft cured this and pretty much made it feel like a new car.

EGR valve blanked off by the AA - the missus clunked to a halt in a cloud of soot as we said goodbye to the EGR. Engine has run faultlessly since leading to a rarely opened bonnet - duly noted by an AA man yesterday after the gear linkage fell off

Tyres - used to eat front tyres on a regular basis until suspension arms were replaced. Cheap tyres are a no-no, we found a good deal on high load Hankook and the Doblo drives as if its had a full suspension rebuild.

Doblo number two

120 multijet family

Bought it at 78,000m thinking it would be nice for the missus. Interior is amazing compared to the sparseness of the original. Much quieter and as ours was the 7 seater I counted 6 cup holders. Six! I was speechless for at least a second or two.

But then within 10 minutes of the dealer we were introduced to the DPF :bang:

To cut a long story short, I've done 20,000 miles since August so you would expect the DPF to be clear. But no, EGR was playing up and within 100 miles had stuffed the DPF full of soot rendering Doblo number two an attractive blue coloured nanny state powered lump stuck outside the house.

So, as thinking about Doblo number two brings on that nervous tick and the tourettes I wont go any further. MOT regs say you cant remove the DPF.

I really really wished I bought an older model instead...

I am not in any way saying you "should" do this, but what you "could" do is, remove the DPF after it cleanses itself (aye, right ) and replace with a straight through pipe.

Then, when the mot is due, remove pipe, replace Dee Pee Eff(ing thing) and do the duty.

The problem with a DPF is it is NOT a solution to the problem, just a patch till something better comes along.

Anyhoo, I will be slated for even suggesting this as an answer as I will be guilty by default of killing everyone on the planet with your cars exhaust fumes. But my job invites me to curse at the stupidity of the masses for allowing the Government to shove it up our own exhaust and proceed to impregnate us with the need to pay tax on just about anything they consider they can make money out of us on.

Seriously, get something that clogs up, so in order to clean itself, it has to BURN off the blockage. Isn't burning causing pollution??

Anyway, I currently run mine without a DPF as it came to me that way and the emissions at the test were so low the tester did it again to check it was right (0.04 and minimal everything else) in case the smoke tester had a fault.

As it is, the other thing a diesel doesn't need is a cat, but hey, more money to be made :bang:

Anyway, I put some serious fuel cleaning additive in with a quarter tank and my car goes like the bat out of Hell. I have to stop now and then to switch off and back on when it starts a DPF regeneration, but it's cheaper than three hundred quid plus whatever it costs for two sensors that were also stolen.

I am sure by my next mot the price will have dropped a bit, but until then.....

The pre-dpf doblo I had was better than the dpf'd version without a doubt.

Removing the DPF is, and always has been, illegal. Serious implications if caught, not least the insurance problems if they find out your driving an illegally modified vehicle.

DPFs are a reasonable solution and work very well in most cases, I'm not sure what better there is that you're expecting to come, short of banning diesels. DPFs, just like the catalytic convertors, are very much here to stay.

Modified?

MODIFIED?

Really?

So, the fact some C**T stole mine makes ME the bad one?

Sorry, but it hasn't been "modified" it has been repaired.

The modification took place in the factory, or before

A DPF is an absolute abomination. End of.

It's not been properly repaired then if its not had the correct part replaced. Its been modified from OEM specification. The fact still remains that you're driving your vehicle illegally.

If someone slashed my tires, I can't just go and replace them with used tyres below minimum tread and get away with it because my previous ones were vandalised.

The problem I had at the time was I didn't KNOW it needed a Dee Pee OFf, I genuinely thought it had been a cat.

It was only after speaking with a mate in the trade that he said it was likely the abomination.

I called my insurance company and told them I modified my car, so it is now on record.

I am not out to argue with you, but MY opinion of these things is they are shockingly over priced, seriously poorly designed and rubbish at the job in hand.

If manufacturers made a modification to the injection system and the way the fuel burns, and fuel companies made an additive, there would be very little or no soot TO burn. But needs must when money is to be extracted from the little guy.

I don't see much evidence of DPF's on the stinking diesel locomotives near my workshop!

One of these monsters fires up and birds fall out of the sky

Yet I am getting the wrath of a Panda bloke for simply stating an opinion and for allowing myself to have been stupid by not realising the bloody thing had been stolen or what it was in the first place.

Since I blanked the EGR, its been fine.

I will also be blanking the egr.

Perhaps I should extend the blanking to other area's too...

Although, I manage to rag the beejeesus out of my engine every day, just to keep the pipes clean

Is this on a 1.9 multijet bud? I've gone and bought a second hand exhaust to make a bolt on de-cat then re-cat for m.o.t muwhaha, unfortunately I'm clueless with dpf and dubious about blanking the egr as I've known blanking plates to eventually burn through

Josh, mine is a 1.9 jtd with a straight through where the DPF used to be.

I had a remap, so dispensed with the need to blank the EGR. But if you use a substantial enough blank I can't see how it would burn through in your lifetime
