MOT addblue delete

[chesterfield hooligan]

If you are contemplating add blue being deleted it may not be this year but in a couple of year's maybe. Sorry again but on Facebook

So you delete the dpf etc after the test.....then reinstate/reinstall it for the next MOT then delete again and so on
Unfortunately dvsa can't see that far ahead.
I believe it's Japan that has strict laws that any vehicle cannot be altered in any way from factory so they fit body kits, wide wheels, tuning boxes etc then remove them for their equivalent MOT then fit them all again....

Not very believable with those sky lights

 

[Ditcha]

Can't really see DVSA investing time and money to detect something that's only a very small minority and with ice cars getting phased out in years to come.

Are you assuming the downloaded data does not include a history of deletions and reinstatement?

If Ad Blu systems for fit for purpose, there would be no need to delete these systems.
Unfortunately, they are not.

Is the Neuro divergent Mechanic a reliable source? Presumably most MOT stations will be aware of these upcoming changes.

Seems odd the customer having to go round to the MOT lane to take the photo. I thought the MOT tester would do that.

I assume the tester has to download the app and take the picture.

It’s going to be an app for the MOT tester (not the end user), used by the MOT tester to prove the vehicle they are reporting to be testing is actually on his premises and physically being tested.

It’s to stop false MOT’s. That’s the sole
Purpose. Even the plug in element way down the line will be nothing more than confirming the vehicle emissions readings they are recording are actually coming from the vehicle via a diagnostic VIN check to stop testers shoving the emission probe up a different vehicle.

It is in no was anything to do with detecting EGR deletion, engine tuning, DPF and/or Adblue deletion as most of these deletions are simply not detectable via a generic OBD port type read, even with most main dealer diag tools it’s not simple to confirm these deletions so it’s well beyond the scope of an MOT unless something can be visual seen to be removed.

Totally agree they need to have random roadside checks and crush any vehicles illegally modified. It would focus peoples minds

My DPF adjustment was carried out by the same place that carries out the Mot
The emissions test is still completed, and passed

The emissions test does not currently include NOX though they have been consulting about it. Reading the vehicle data may be a cheaper alternative.

 

[Steve and Denise]

It would help if manufacturers made a system that was fit for purpose,
We only own one diesel powered vehicle now all our others are petrol.
I would suggest there could be a much bigger reduction in pollution if the government’s stopped flying about the world ie Copt 30 50,000 Deligatets and destroying 10,000 acres of rain forests
Sounds like a comedy script

& in Italy they have made the manufacturers totally liable for any repairs necessary .I believe peugeot have alos had to swallow eu wide the costs of engine emissions problems

how do they overcome the "cannot test anything that needs to be opened,unlocked ,etc,etc" when you have an obd lock & they cannot access it? Or even you have deleted it & replaced it with one with 12volts on all pins to prevent theft?

Problem is ,it is more or less undetectable. You cannot detect that a catalyst has no internal honeycomb nor that a dpf has nothing in it either as long as the emissions are correct?

Simple answer - they don’t at present.

If a catalyst was removed then more than likely (to prevent MIL illumination) the system (lambda sensors) will be mapped out is it would almost definitely fail an emissions test. The above MOT changes at a lame attempt at trying to stop MOT testers faking emissions test.

With regards DPF removal - that’s simple. The MOT needs to include a soot test, however soot testers are super expensive so probably never going to happen.

If you have access to a decent obd scanner you will have access to certain PIDs that easily indicate a deleted DPF or mucked about with emmissions system. with Multiecuscan I have identified a number of vans that have been doctored. The differential dpf pressure sensor wiill show zero at all revs, even if very low/ clean eg 5mbar it still varies with revs. There is also a pid "distance to last regen" this helps decide how blocked the system is and in a working engine could be has high as 800miles but if its say 2000mile then an obvious delete. If these tests are mapped out then thats an indication to a delete (no other reason for doing it). This is not rocket. I have tests on a couple of differrent deletes including a simple LPEGR delete on a twin egr. This later data was obtained from New Zealand where it was legal to do these Mods. There are too many dealers/sellers trying to pull wool over peoples eyes selling deleted product to unknowing punters.
PS ive recently seen a scanner danner vid on a Peugeot version of the fiat doblo and scantool says replace adblu tank, he strips it. its not just a tank but full of interesting gubblings that stellantis dont list spares on the refurbed tank @ Euro 1500.

If the emissions are correct without them they wouldn't need to be fitted. Are you saying that you emit the same amount of particulates with a pdf that's working as without one

You overcome it by a non readable obd port being an automatic mot fail!

My understanding is they don't do a soot test at MOT so wouldn't know if it had a DPF that was working or not so it's down to the tester to see if the DPF has been tamper with or removed totally that's the only way they can tell.

Makes you wonder if the mot is the best way to tell. If the soot testers are expensive and not very common maybe they ought to be doing it by roadside tests.

The DVSA might do the tests roadside not sure.

 

[oldiesontour]

I was told over a year ago by an MOT garage owner that his ministry inspector had told him particulate testing is to be brought in...he als said 99% of over 5yr old cars will fail

 

[the1andonly]

I stumbled accross a forum of MOT tester and DVSA people where various trials and discussion group info was under discussion, interesting it was.
The number of MOT stations is decreasing because of profiterability, government wants more testing and expensive equipment so has been doing various tests around the country. The sticking point is the price the majority want a fixed price and no discounting it has been static for 14yrs and more added each year. in a few years we could see a vastly different test and price upto £100. New difficult tests is one way of increasing transition to EV.

I agree it will speed up the transition but if people didn’t try to cheat the current standards there would be no reason to change the test.

 

[Guigsy]

NOx are mostly produced when the engine is hot and under sustained heavy load. It's hard to test. Hence the reason manufacturers got away with dieselgate for so long.

As an FYI
My other car is a Citroen.
It was returned, under warranty, to the main Citroen dealer 4 times due to an AdBlu issue.

The first time they simply cleaned the AdBlue tank - It was back in the garage within 200 miles.
The second time they replaced the AdBlu tank - it was back in the garage within 200 miles
The third time they replaced the entire AdBlue system, plumbing, tank and sensors. - back to the garage 200 miles later
The fourth time the problem was "fixed".

I did not put any AdBlu into the vehicle for the next two years.
It went into the garage a couple of months ago for it's annual service and MoT.

For the first time in the four years and 45,000 miles since I have owned the vehicle I have put in 10 litres of AdBlu !
I had to find out where to put it in, never having needed it before.

I'm guessing the DVLA have let the major dealers know a mapping out the AdBlu clampdown is on the way!

Yes.
For some reason the rest disappeared?
If Scania can make vehicles that meet current emissions limits without using dpf's then all manufacturers should be able to.

That's a big difference from removing a dpf from a vehicle designed to have one fitted to meet the emissions standards. If it's removed and the vehicle meets the emissions standards no problem. If someone has removed it because they're not bothered about inflicting their emissions on someone else that's totally different.
