DPF cleaning

[Wooie1958]

Thanks Graham, just ordered some.

For the price of a pint every 3rd tank I reckon it's worth it, I certainly don't want to be replacing the DPF again anytime soon.

No problem Rob

I`ve tried several different makes and the Liquid Moly seems to be the best IMHO.

Our car comfortably does 500 miles before refuelling and that`s only taking it down to approx 1/4 full so you don`t get any of the crap in the bottom of the tank in the fuel line, i also religiously change the oil and filters including the fuel filter yearly even though sometimes we only do 3,000 to 4,000 miles.

Forgot to say that i only use quality oil and filters.

Castrol Edge Hyspec 5W-30 LL 504.00/507.00 and Mann filters.

It's also probably a good idea to check oil specs match what is recommended by vehicle manufacturer too, especially with newer models which are likely to require a low SAPS / low ash oil.

I don't know if oils have always had a shelf life but synthetic ones do, usually 5 maybe 7 years. So when you see quality, correct spec oil on e bay for a bargain price, there is a good chance they are getting towards the end of their shelf life. The date of manufacture will be on the container.

Millions of years in the making below ground, yet a shelf life of 7 years max in a plastic container full of additives ... Where's Fred Flinstone when you need him? Arguably, he became the father of the oil industry when he had to have Dino, the snorkasaurus put down ...

From the .Gov website;

Fines for drivers​

For drivers, the penalty for driving a vehicle with the diesel particulate filter removed, are fines of up to £1,000 for a car or £2,500 for a light goods vehicle.

Undeclared illegal modifications (like removing a diesel particulate filter) could also invalidate a vehicle’s insurance, so it’s not just garages who could face serious consequences.

I expect it's because removing the DPF will also improve the vehicles performance, but I also read elsewhere that a vehicle without a DPF is considered unroadworthy. (RAC)

You have to love these scare stories. You have to read the words, not just the impression you get from them.

Removing a DPF is not the same as deleting a DPF in the ECU programming.

It maybe 'could' affect a vehicle's insurance.
Note that they don't claim it 'would' affect it.
And that they don't claim it could 'invalidate' the insurance. Just could 'affect'. What does that mean? What does your insurance policy say on the matter?

Yes, you can "read elsewhere" all sorts of balderdash. The RAC is a vested interest group,

Note, I'm not suggesting you should delete or remove your DPF or your EGR. Just saying that misinformation usually outguns factual information.

It's correct for the UK Government Website to state 'could affect' [sic insurance], because the Government is not the arbiter - the insurance company is. The Government has set the fines range, and 'factual information' is tautologous - if it's not factual, it's not information, but misinformation, rumour, innuendo, lies or propaganda

If the DPF is removed or deleted, then the vehicle is not roadworthy; ergo, that puts the insurance at risk, if stopped by Police or involved in an accident

Exactly. If you don't get caught, it won't, so could is correct.

What scare STORY are you going on about,
This is not a story and whether you could or would lose insurance cover is irrelevant.
The fact that you COULD end up with no insurance should be sufficient to deter any sensible person who owns a home or has life savings from driving about with their van or car with their ECU programmed to run without DPF.
Having had to deal with insurance companies over the years, one thing I learned was not to give them a way out, because even the good insurance companies will take it if the claims large enough. And a road accident can lead to claims running into millions.

Your last two lines are a complete contradiction from the rest of your post.
You refer to this as “ balderdash” if what you are proposing throughout your post was correct there would be no point in not removing the system, other than concern for the environment, or having a clear conscience.

Note, I am saying that anyone who deletes or removes their DPF may well find out that this is no story, and may well wish they had never done so.

Well are you feeling lucky

I think everybody knows that Insurance companies will use any means they can to get out of a claim as others have stated. If you don't believe that then I think that you are being a little bit more than naive.

I don't think I said anywhere that removing a DPF is the same as deleting it?

I very much doubt the glow plug NEEDS to work to do a regen. It is silly engine management software.

A previous car I had put an engine light on for a glow plug fault, and while that error was there it disabled cruise control. A failed glow plug should absolutely not stop cruise control working it is not related in any way whatsoever.

 

[gypo]

The glow plugs are required to do a regen on fiat ducato 2.3jtd 130 . They preheat the diesel before it is dumped into the dpf.
You can force a regen if your plugs are working going through a sequence with feet on the brake and accelerator and key off and on, I’d you Google it the sequence is available.

 

[mikejay]

Not sure if it's been mentioned but it is very easy for anyone to spot if you have a failed dpf (cracked) or removed by taking a look at the tail pipe. So easy for vosa at the side of the road or mot guy the tailpipe should be spotless if all is working correctly no sooty finger.

No, I refer to generic stories you can find on the web as "balderdash", and I make that clear in my comment. I don't think it was open to misunderstanding.

There is no point in discussing with someone who is unwilling to read what I write, but prefers to comment based in their preconceived misunderstanding

I completely agree

It is illegal to remove the system. I think that would be the primary point.
My van never had these things, because it is old. My conscience does not make me want to fit them.

Concerned for the environment? Don't fly off on holiday.

That’s exactly what I was trying to say Rob.
I see no point in paying hundreds of pounds for insurance then giving them a way out.
I have been in that situation myself when making a claim from travel insurance.
I made an honest mistake and they washed their hands.
I have heard of people losing out on claims for six figure sums on medical insurance due to them not disclosing something that had nothing to do with their claim.

Yes I know someone who was caught.

Do dpf cleaner's work , answer nobody knows.???

Be interesting to know what happened to this person if you know?
