How many cars are going to fail the new MOT due to emissions?

 

I've been thinking about this a lot and it doesn't really effect me as my MOT man is quite happy to put it on another car to pass the MOT (open for debate I know). I love new technology and am myself very green, I have numerous bins for recycling and have solar panels on my home however, I have a 2007 Saab 1.9 DIRTY diesel (I know I'm not perfect). 

 

I've had this car for around 8 years, it's covered 175,000 miles. 7 1/2 years ago the DPF blocked up and I had it removed along with a remap (it wasn't illegal then), the car went from 150BHP to 210BHP and has around 400 torques, pretty quick! Very fuel efficient too, it went from 55MPG cruising at 66MPH to 67MPG . Brill! No warnings on the dash and several MOT emission passes without a problem.

 

Now... the MOT from the 20th May this year, hmmm... After having some work done on my car I asked my mechanic to test the emissions (the limit is printed on the bottom right in a box normally on the passenger bit when you open the door). As far as I can work out from reading this... https://www.gov.uk/g...emission-limits. My emissions came back at 0.97 and my limit being 0.50 (double). Previously it had been tested (I think) at a limit of 3.0 and obviously passed with flying colours. Now it says on the government website that if the plate can't be found it has to be tested at the default, so if my plate magically disappears (as well as some other members on here lol) would that car still pass? I know they mention about tampered DPF's and ones missing, mine was hollowed out and appears to still be there, there is no way anyone would know, again it's passed MOTs before and not just by a friendly mechanic.

 

Maybe I've found a loop hole some members can benefit from or maybe I've opened a can of worms for myself :p

If you obliterate the value on the plate then the tester has to use the default limit instead. My own tester told me of this loophole months ago.

Diesel is one of the biggest scams to date. The government got people to rush by the score to buy diesel, tempted by its cheap price and its fantastic economy. Now its more expensive than petrol and they want rid.

 

I've got a diesel Citroen C5 executive currently at 250bhp and fuel goes around 27 mile urban or 40 extra urban. I've seen this im considering getting -

If you car fails do they just expect you to dump your car, or get a whole new (expensive) fuel/filter system ?

Not to mention the talked about taxation to enter city centres with diesel cars.

Not sure what they will do about busses and wagons that spew smoke out of them when they set off from a standing start.

Diesel is on its way out. Even the buses etc are starting to move to other fuels as cities and large towns can't meet emissions targets whilst allowing them to run. Trains still use diesel but per person travelling it's a lot better than cars. 

 

With regards to tampering / modifying the DPF - if you're found to have done so then it's a £1000 fine and you'll have to get a proper one fitted in order to carry on using the vehicle. It is the driver that is at fault here regardless of whether they did the work themselves.

So whilst this can seem to be a good idea, it's not without its risks...

Yeah mines hollow, but looks like it is still there. It'll be interesting to see how they can detect it doesn't have one.

Do you know how they were able to remove the innards? (Asking for a friend)

My VW Golf 1.6 TDi has had the VW ECU remap done over a year ago. It's 7 years old and a recent MOT gave it ZERO, yes ZERO emissions !!!! Petrol engined cars give out more carbon and micro carbon (soot) emissions than a diesel

engined car.

A few years ago the government were urging us to buy diesel cars, now they have changed their minds ???

My Golf can get 66 mpg and the last Tax Disc cost £30.

The Japanese are developing a more fuel efficient and eco friendly diesel to rival electric cars.

 

If we all had electric cars, just think of the problems, how do people who live in high rise flats charge their cars? How can the National Grid cope when everyone comes home from work and plug their car into a charger ????

It just can't happen, not now and not for many a year until battery technology has advanced beyond our present capabilities.

 

I think we should, like the Japanese be researching how to build more eco friendly diesel engined road vehicles.

 

Don't mess with the DPF or anything else as it is an MOT Fail.

 

What are the views that any vehicle over the age of 40 years does not need an MOT!!!!  

 

Anyone got a Ford Transit MK1 Diesel van for sale ?????? l :) :) :) :) :)


If there's something strange in the neighbourhood, who you gonna call ?????   The Council !!!!!!!!

As the new test is no longer just a visual check it is quite likely that the erm, faulty DPF will be picked up.

 

The new test is designed to test the effectiveness of the DPF so if the inside filter is missing then this will probably come to light.

 

http://garagewire.co...-dvsa-confirms/

 

IMHO it's a good thing as unfiltered diesel engines pump out a huge amount of toxins which affect both people near the car and the driver and passengers.

 

Longer term cars are likely to be hybrid at a minimum, if not fully electric. The biggest obstacle now as stated is the "last mile" getting charging down to the house / user. The amount of $ invested in the technology though means that this is very likely to be overcome with a mixture of improved batteries and much faster charging. Even mid/high end sporty models (such as the upcoming Mk4 Focus RS) are adding electric motors to give the petrol engines the startup torque to rival the diesels.

 

Interesting times for the motor industry I think...

Not sure how diesel cars give out ZERO emissions. Pretty much impossible to have ZERO emissions other than electric cars. They have to give something out, that is the nature of the combustion process. If I were the tester I would have the test equipment checked if I was getting no emmisions from a combustion engine.

If Dpf's have been tampered with and things such as innards removed, it must stand out like a sore thumb on test equipment. The amount of shite spewing out will be huge.

Can't see many garages risking passing blatantly tampered with cars now, they have too much to lose and rightly so.

25 years ago i went to a faraday lecture at the Brighton dome - sponsored by the Ford motoring company.

 

cut a long story short, they were toying with cars that could run on water. the idea is that the hydrogen is extracted and burn off in the car - leaving harmless o2 and co2 to evaporate into the atmosphere.

 

I have absolutely no doubt the idea has now been pioneered, and then locked away in a vault; probably belonging  to the likes of BP or shell.

What pisses me off is my car's nissain tino automatic petrol 2005 yet my road tax is far dearer than my dad's diesel 06 estate. His is approx £100 cheaper than my £285 a year tax and why don't they scrap road tax and place it on petrol n diesel as said my £285 is for 7,000miles a year where as someone paying £30 a year does 20,000 polluting the environment far more than me, where's the justification in that!
Also I would love to get a new car but simply can't afford to so I'm stuck in a big deep hole!!
@nails
I wouldn't see as water power is the way to go as there isn't enough useable water to go around, in my eyes solar power would be the way to go, far to much sunshine or daylight is wasted, a different subject but regarding solar power I think all new builds should have solar panels automatically installed on roofs etc

I certainly think electric vehicles are a flash in the pan. Tesla was reported to be on the verge of bankruptcy as they cannot produce the cars quick enough, the cars are costing more to produce than the price at what they are selling them and they are now struggling to attract further investment.
There are no way enough chargers at this time to accommodate the few electric cars on the roads. There are the inflated costs of having fast chargers at your property, if not it is a 13amp plug in charger that will take a week to give a full charge.
Read a brief thing on a bmw i3 I think it was a while back and they advertise 200 to 250 miles on one charge, when realistically with lights on, air con or heating, stereo on and not driving like a saint everywhere, it brought it down to about 80 miles.
As soon as the manufacturers crack the emissions on petrol engines (maybe diesel later in time), making the emissions very low, making the cars with super clean emissions a reasonable price then electric will be a thing of the past or will be part of a hybrid system that gives initial pull away power.
Ford have the 3 cylinder 1.0 Ecoboost 140 petrol engine now that with a remap will give approx 170bhp in a fiesta. The new St looks like it will have the 4 cylinder engine that rests one of the cylinders until the power is needed, again a small engine that is very clean.
Just my thoughts but we will see....

That's just what your emissions should be Nails.

 

aamusements, they take off the dpf, cut it open at the top, chizzle the inners out, weld it back up, smooth off the weld and put it back on the car, remap the car and the job is done.

 

Mavroz, If the DPF is visibly still there and the emissions are within the guideline, how on earth can they prove you don't have a dpf installed? That site also mentions about so called performance increases, well that is correct, the car achieves 12MPG more as the engine isn't strangled with a dpf filter installed and has gained 60BHP and 80 more torques. 

 

Maybe an adblue system or hydrogen system would work better than a DPF, something like this... https://www.cgon.co.uk/Home/FAQ

The only problem with electric cars is that they arrived a hundred years too late, the oil industry made sure they couldn't compete since the early 20th century and now they are only just becoming popular again.

Isn't taking the innards put of the dpf the same as using a decat pipe on a petrol. People use these for daily running but put the cat back for mot purposes.

The hollowed out dpf must give out something detectable that it wouldn't as a functioning unit when the exhaust is probed. We will see sooner or later if and when cars get taken off of the road and owners fined.

Here is a copy of my current M.O.T. (Pass) (Reverse Side) of my 7 year old VW TDI (Euro 5 ) Diesel Golf (blanked personal data)       Zero Emissons.

 

No the testing station equipment wasn't faulty either.
