Just say for instance you took your car to awesome for a dpf delete. Then you took it back to them for an mot. Would they then fail it? Technacally they would have to wouldnt they?

The tester would probably conveniently not be the person who removed the DPF...

I've often wondered about this.

Numerous firms that do MOTs also do work that makes a car illegal for road use.

Conflict of interest.

So how would they breach this subject if asked i wonder?

Nervously I'd imagine.

How do they know your other half doesn't work for VOSA...

Where I work, we refuse to remove DPFs or Cats, we will fit a sports cat but if someone else brings a car to us, even if we know the car we can only work on what we see and what the figures say on testing devices. If a car unknowingly has a fake DPF casing it will get a pass if correct on figures as we can't do anything otherwise, not allowed to remove or adjust anything on the vehicle.

Thought this myself as just a couple of miles from here is Top Gears (car tuning place/website business not the tv program) main headquarters and they do regular servicing/MOT work as well as all the tuning stuff. They do DPF/EGR deletes and if I ever went that route I'd take it to them from them on and just let them try and fail it. Best thing would be to actually ask before having it done and get any "we wouldn't fail the car" response down in writing.

I don't see why a lot of testers do things like that, one report or Vosa inspection and your licence to test is down the pan as well as a business section if you're the only tester and a source of your income. I will be awkward when I pass my vosa licence as I value my employment

Even if the garage removed the DPF and then tested and passed the same car their response to any enquiry by the DVSA would be that the car passed the DVSA's test according to their own standards.

 

The garage followed the MOT procedure to the letter and it passed, even without the DPF in place.

 

Is there a section of small print in the MOT standards that suggests that if the tester is aware the DPF is missing, regardless of if the test shows otherwise, then they have to fail the car?

Exactly, we can only go on what is Infront of us within that hour

Spot on mate

Yup. 

Last MOT, I got an advisory because of the undertray - they weren't able to see underneath.

Happens alot especially on modern cars with more undertrays,

 

Its a way of tester covering his back really,

 

As toxic says they can only test on what they can see,

 

If they can see a dpf box and its all connected up and it passes smoke test then it will pass MOT,

I've seen cars before with tape covering the rear arch thoroughly and we can't remove it to fail the car

They would be utterly stupid to sign a document saying they won't fail the DPF delete they just did as if you ever got annoyed with them over anything you could send it straight to VOSA as proof they are incorrectly carrying out MOT tests.

 

The MOT check stuff I've read doesn't specify how to identify if the DPF is present, though I would definitely imagine it wouldn't be unreasonable that if the same guy who signed for DPF delete work on a car then signed the MOT they could be brought up on it by VOSA as it could be easily argued they had knowingly passed it in a state that they know it should fail.

 

I did also read VOSA want to start revoking MOT testing status from places that offer DPF deletes, so that will also answer this question.

 

I don't know why people still think this is ok. There is a constant tide of stuff coming and saying its not OK yet people still stand there, with their ears covered and eyes squeezed shut as if it makes a difference.

For that reason I highly doubt they would put it in writing but by doing so they are then admitting that the car is totally illegal under the new regulations so why continue to offer the DPF delete? I just do not know how a car that has had a DPF delete can legitimately pass the 'smoke' test level for that DPF equipped model if it's been removed. Luckily I've not had any trouble with my PD Vrs (never even had the DPF light on yet) and long may it continue. If it gets to a stage where it becomes a problem, then at the age it'll hopefully be at by then (8 years old come May) I'll just bin it and go back to a Petrol. This is my first Diesel car and although it isn't as prevalent in my mind as it was when I first got it,I do still tend to drive it at higher revs than I would normally like to and that's just to try and not get get DPF/EGR issues.

As I see it there is no point in a DPF delete

I used to drive my PD with a DPF in a manner that was friendly to it and the DMF. I never had the light come on, but it was always nagging me in the back of my mind. Now I have a petrol, I just drive it. Can't be bothered with that rubbish anymore, plus the speed with which it warms up in winter is fantastic.

Well when it goes tits up,owners have a choice of £1000+ for a new one or a few hundred on getting rid of it. Not to mention those that have got rid of it just for the bhp gain from removing a not unsubstantial restriction and the subsequent remap that goes with it.

Isn't it illegal to sell a car with the DPF or cat removed?

Probably but lack of proof etc.

They could get their authorisation to conduct MOTs revoked.  The text from the special notice that covers this:

 

Item 2: Diesel Particulate Filters

On the 16

th

February 2014 the Diesel Particulate Filter (DPF) became a testable item. Any vehicle where

a DPF is missing that was fitted as standard should, from then, fail the MOT test. This was brought in with

Special Notice 1-2014.

The DPF plays an essential environmental role in enabli

ng reductions in emissions which help meet strict

European emission standards, reducing air pollution and thereby improving health quality.

DVSA are aware of an increasing number of businesses offering a service to remove or bypass the DPF.

This practice compromises the MOT testing standards and therefore undermines the principle of

inspecting their presence.

Authorised Examiners are responsible to ensure that MOT Testing is carried out to the required standards.

Where a VTS is offering a service which could undermine this (such as removing or bypassing DPFs)

DVSA will consider this as bringing the MOT Scheme into disrepute.

Where the scheme is brought into disrepute DVSA may cons

ider taking action to remove the Authorisation

if appropriate.

I imagine a main dealer would know how to check it easily enough and tell you you can keep your part ex. A simple look at the exhaust should show otherwise. My Octavia had 120k on the clock when I sold it and the exhaust was still pretty clean.

 

And yes, it would technically be a criminal offence as you are selling a car that is unroadworthy. This applies to private trades too. You sell it on and if your buyer takes it for an MOT and it fails on a DPF delete, you can get into quite big trouble.

Yeah it'll probably show up on their system, I was referring to a private sale with people who didn't check

Even if you don't check at the time of purchase, the seller is still on the hook for selling an unroadworthy vehicle if it comes out soon enough after.

 

Its not a subject that has been raised in any of the previous DPF threads, I don't think, that any car with a DPF delete is effectively illegal to sell (even privately).
