Van's losing power every now and then.....it's going for a regeneration doing to it next....guy said if that doesn't cure it they can take it out and run without one.
Have read up and it 's illegal to do this but a much cheaper option.....anybody had their DPF removed and if so any problems.

They can be a nightmare but better to try and keep it in because it may not pass an MOT. Plenty of other things can begin to go wrong when removing it, mainly the software. It ends up going on a loop to try and find it and sometimes the immobiliser kicks in. I used to go a long drive once a week until I read about small metal discs that go into the diesel tank. Bought them for £40 for five and haven't had any issues since and that was years ago. Mike Brewer was advertising them, I thought it was a con but they worked for me.

Software won't be a problem.....it's more the "legal" route I'm thinking of........they're only about £400 to buy so why is fitting a new one so costly?

You'll only need one MOT checker to suspect and find it has no DPF and this info will get sent to DVLA which will essentially stop you from getting an MOT test anywhere unless you have the DPF reinstated and software put back to how it should be which will cost a hell of a lot of money. Law on DPF is far stricter than it once was with testers being struck off if they pass a vehicle they suspect to have had its DPF removed.
Lots of good businesses that specialise in cleaning or replacing DPF, back street garages usually mess this work up, so research who you use.
-
They've been on about bringing in a specific particulate test as part of the MOT. for years.
But with our current administration, it may well become a reality.
Just something to bear in mind.
-
Going in Wednesday for cleaning which hopefully will fix it.........any ballpark figures for replacement price,,,priced them up to buy at £400ish.......can't be that much work to fit and re programme.

What van have you got and what mileage has it done ?
-
2015 Transit Custom with 48,000 miles on clock......just flown through another MOT 2 weeks ago so was well chuffed then this.

Whats making your mechanic think there is something wrong with the DPF ?

The plug in machine readings......

The plug in machine readings......
Couple of things puzzling me. You say your van is losing power occasionally. He's diagnosed clogged DPF i assume, due to these readings. He'll be able to tell if its full of soot etc... based on the readings. The DPF should be able to regenerate and clean itself. But for whatever reason it hasn't . It is easily possible to remove them and have them cleaned. But he's jumped ahead..,.suspecting, even as chance that this may not work and you could remove it ?
He doesn't sound confident at all to me.
As someone else has just mentioned, the law around DPF's and emmisions is changing and getting tighter. Removing a DPF, even in software could be a costly mistake to make. And probably uneccesary too.
I'd be going to someone who specializes in DPF's.
-
Sounds like a turbo problem to me.

The guy who took the readings wrote everything down one of them reads "soot content high" but couldn't spend any more time with it as I went in because I was working next to the place and he broke off to plug it in and test it but couldn't do much else for me for the next 2.5 weeks as was mown out.
Went to auto electrician I've used before and from the readings I showed him he thought it was, for some reason, not regenerating so was going to try a regeneration I think he called it........he also mentioned replacement or removal.....I'll know more Wednesday when I take it in......removal without replacement isn't happening.........no warning lights are showing either.......I only do about 3500 miles a year and actually have to go for a run out on motorway to try keep it clear..............funnily enough did a 5 mile round trip today and no problem.

The garage can do what they call a forced regen they can do this several times but if the DPF is choked up it will need removing and cleaning or replacing
-
That's what they are doing a forced regen......I will take it from there.....after googling removal of DPF and the consequences I won't be going down that route.

For all those suggesting an EGR valve and dpf delete, our mot inspector told me they now have to plug their system into the OBD2 port to read engine oil temps and emissions.
That OBD report from the vehicle is included with the report that goes to the dvla. That report includes the vehicle's chassis number read from the ecu and of course, the chassis number has to match the vehicle's registration number which is checked at the start of the mot. They will be able to immediately identify if the EGR and dpf components are missing. These more stringent mot test became into force this past October.
These tests also require a photo of the vehicle to be taken showing the vehicle's number plate with the test in progress.
Our next door neighbour's son had his dpf and EGR deleted on his BMW. It's going to be very interesting how his car is going to pass with the garage that had them removed.
-
Get them to check the vaporizer first.
If the vaporizer is clogged, your van wont be able to go through a regeneration cycle and therefore will clog up. (The vaporizer injects the fuel to burn off the soot when going through a ‘regen’ cycle; google it, it’s a semi common issue on Customs once they get to a certain age/use)
You’ll also have an idea of whether it’s failing to ‘regen’ by checking the oil quality.
-
Over here in Canada, I don’t have to concern myself with MOTs, they don’t have them here.
Nor road tax.
-
A dpf clean needs to be done in 2 stages.
The first stage is to remove the soot and then do a reverse flush to remove the ash. If the ash chamber is full, then doing a forced regeneration isn't going to solve the problem.
This video clip of Jimmy O'Rileys Auto on YouTube explains it perfectly.

Really? So no test whatsoever to see if your vehicle is roadworthy?
-
Much ado about nothing........remove EGR valve....clean....put EGR valve back in.......DPF is fine.......

I believe roadworthiness is a law, slightly different depending on what province you’re in. In BC there’s nothing that I’m aware of and have never been asked for.
There’s a Scottish guy here, called Callum who I’m pretty matey with. He’s a tree surgeon. I saw his truck parked up outside the bank last week. BIG eff off wheels on it. Tyres were bald as a coot!
I’ll get a pic next time I see which’ll probably be Thursday, I see him most Thursdays 😀

I think he needs to get his wheel alignment done.

South Africa doesn't have an annual vehicle inspection either. The only roadworthy test is required when transferring vehicle ownership.
Zimbabwe also doesn't have an annual roadworthy test either. (I also don't ever recall my father having to have his vehicles inspected in Zambia either.)
In both countries there is a vehicle test station as part of the new driver test centre. If your vehicle is stopped by the police and deemed to be unroadworthy, then you are given a ticket to report to have your vehicle inspected at this test centre.
Having lived in both countries, the owner of the vehicle is responsible to ensure his vehicle is in a roadworthy condition. Rust was not an issue. So roadworthiness was ensuring the vehicle was kept in good order mechanically.
Unfortunately, a large number of vehicles on the road in South Africa would fail a roadworthy test mechanically in this country.
And the other issue is untaxed, uninsured cars being driven by people with no drivers licence.

Strangely - here - once a vehicle reaches 40 years old it doesn't need an MOT.
My 44 year old Suzuki GS850 hasn't had an MOT for four years. Although I personally have it checked over by an MOT tester every couple of years just for my peace of mind.

Didn't Starmer announce recently that he was going to introduce an MOT requirement for all cars on the road no matter their age?
Another thing that amazes me is that caravans and trailer aren't registered and taxed in this country. Oversees they are and carry their own number plate and have to display a current tax disc.
