DPF instant MOT fail

[Petrol Pete]

Good

As I said a few weeks ago this new test requires people to change the way they approach the MOT,you need to be there none of this leave it and pick it up lark,if you are in any doubt about smoke,then get the car low on diesel and then put in a big dose of engine cleaner in a quiet area then rev it in a low gear clearing out all the crap,then fill up with diesel at the MOT station make certain that you rev the car at around 3000 revs for a couple of minutes this will heat up the exhaust gasses and should help to pass the emissions test,if you have removed the DPF then that is likely to be a fail no matter what.

Good advice, and yes, no DPF = instant fail, in fact if your DPF has been removed don't even bother booking your car in for an MOT you will just be wasting your time and money after May 20th.

Removed or visibly tampered with

I believe you can take a failed vehicle away from the testing center to get it repaired and drive it back to the testing center for the retest.
You can't drive it around all week whilst you think about it. The car is unroadworthy final.
If you know your car is dodgy take it for a test on the last day of your current MOT and then you're breaking no laws.
I've restored a few old cars and you have to book a MOT at the nearest to you and then you're allowed to drive it to the test center for the test. That of course is for vehicle's that don't have a current MOT !

You cannot legally do so if it has a 'dangerous' fault.

You don't have to book an MoT test at the nearest testing centre if a car's MoT has expired; you only have to be on your way to a pre-booked test. Mind you, if you booked a test on a Saturday morning at a centre 150 miles away, which coincidentally was next to your girlfriend's house where you intended to stay the weekend, if stopped you might have problems convincing a traffic police officer that you were not committing an offence...

It will be interesting to see whether smoke from the exhaust of a diesel, or a missing or tampered-with DPF, is classed as a 'major' or 'minor' fault; I can't see it being a 'dangerous' unless it is absolutely belching smoke. As I read it, it would seem that you will be allowed to drive a car with a 'major' to a place of repair (see my previous post if the place of repair is 150 miles away...).

Somebody also made a very good point about buses (and to a lesser extent taxis), many of which seem to emit some smoke at times; that, too, will be interesting.

The whole thing is a can of worms due to 'interpretation'. A loaded gun is not dangerous...until someone picks it up.

You can at the moment but this all changes on May 20th for failures classed as dangerous.

There's a bit of confusion by conflating two issues here. The new regulations concerning diesel emissions and the categories "major" and "dangerous" fault. I can see a car being failed on its emissions being classified as having a major fault but its very doubtful this could ever be classified as dangerous!

What about those without DPF's, I can see smoke after a brisk getaway

With thousands of people reportedly dying yearly in the UK as a result of diesel emissions, that sounds pretty dangerous to me. Of course it’s a moot point as to how dangerous individual vehicles are.

If you can't drive away from the MOT station with a failed vehicle what do you do if the MOT station doesn't do repairs ?
The one I use only does tests and so do the DVLA ones...

Recovery vehicle, flatbed?

 

[OneForTheRoad]

faults that were dangerous ALL the way to the mot centre but yet you arrived safely lol .

A decent mot tester that knows the owner can log it as a major on the system , enough for you to get it sorted without all the kafuffle.

 

[whitenemesis]

One of the criteria for a "Dangerous" flag is the vehicle's effect on environment, DPF removed?

WTF are you on about? Just what has that completely false statement got to do with my post, or indeed any other post in this thread?

All these changes stem from the 2014 EU Roadworthiness package.
How the EU Roadworthiness Package affects the MOT - Matters of Testing
The legislation contains some interesting things to say about vehicle electronic safety systems - portents of things to come perhaps?
How would you test for the effectiveness of the vehicle's electronic stability control other than the systems warning light on the dash?
For the inspection of vehicles, and especially for their electronic safety components, it is crucial to have access to the technical specifications of each individual vehicle. Consequently, vehicle manufacturers should provide the data needed for verification of the functionality of safety and environment-related components. The provisions concerning access to repair and maintenance information should likewise be applied for that purpose, allowing inspection centres to have access to all information necessary for roadworthiness testing. The data should include the details that allow the functionality of the vehicle safety systems to be monitored in a way that allows such systems to be tested in a periodic technical inspection environment. This is of crucial importance, especially in the field of electronically controlled systems, and should cover all elements that have been installed by the manufacturer.

Article 7

Assessment of deficiencies

1. For each item to be tested, Annex I provides a minimum list of possible deficiencies and their level of severity.

2. Deficiencies that are found during periodic testings of vehicles shall be categorised in one of the following groups:

(a)

minor deficiencies having no significant effect on the safety of the vehicle or impact on the environment, and other minor non-compliances;

(b)

major deficiencies that may prejudice the safety of the vehicle or have an impact on the environment or put other road users at risk, or other more significant non-compliances;

(c)

dangerous deficiencies constituting a direct and immediate risk to road safety or having an impact on the environment which justify that a Member State or its competent authorities may prohibit the use of the vehicle on public roads.

3. A vehicle having deficiencies falling into more than one of the deficiency groups referred to in paragraph 2 shall be classified in the group corresponding to the more serious deficiency. A vehicle showing several deficiencies within the same inspection area as identified in the scope of the test referred to in point 2 of Annex I, may be classified in the next most serious deficiency group if it can be demonstrated that the combined effect of those deficiencies results in a higher risk to road safety.



ANNEX1 makes for interesting reading on failure criteria- how much of this has reached UK MOT regs I don't know?

It's that word 'reportedly' again. Do quote your source, would you? Otherwise it's just 'lies, damned lies and statistics' as reported/spun by the media, isn't it?
