You are just being childish now.

So what check do they do then to confirm there is a dpf IN the dpf box then?

Who said an MOT Tester is only allowed to check a DPF visually?

The MOT rules, that's what. In the MOT the tester is NOT ALLOWED to remove/disassemble anything. As you cannot check to see if the internals of a DPF are present without taking the exhaust system to pieces, the test can only check with their eyes to see if the DPF casing is present.

Emissions are tested but passing that is not really down to having a DPF or not. A diesel emissions test is just a visual check to see if the exhaust is producing smoke. A car can pass that test without a DPF.

A MOT tester is not even allowed to remove a baby seat to check the seatbelt anchoring that baby seat to the car. As they can't check that seatbelt, they cannot fail you for any issues with it as they can't test it's sturdyness etc.

A MOT always has been a visual check of things that cannot be taken apart/removed and a physical prod at things that can be checked without taking anything off/dismantling.

You can download and read the MOT tester's rulebook from VOSA if you wish to check for yourself.

But feel free to post up the Reg No and MOT Cert details so I can inform VOSA.

Let VOSA decide.

VOSA closed down 2 years ago - shows you how up to date you are! :rotfl:

Oh those are just random pics of said elements from the internet.

My point being, those are all perfectly legal for MOT and yet you cant actually say whether there is a DPF core in there, a catalytic converter in there, or an airbag, respectively.

Unless there is VISIBLE evidence theres nothing they can do to fail any of those.

The next time I own a Diesel with a DPF I will happily allow VOSA to inspect my car fully at any point in time to confirm that it is fully compliant with Construction and Use Regs.

VOSA are closed.

I assume the owner of the vehicle concerned informed the Insurance Company they use that they have modified their vehicle from standard?

I've no idea whether the cars in those pics have a working dpf, cat, or airbag. Neither do you. Neither would an MOT tester.

In fact DVSA wouldnt either unless they pulled the car apart.

bigjl wrote: »

Or are you saying Insurance Companies are fine with such modifications? And do you have a letter of the confirmation of this fact in writing? You can post it up with the owner details redacted if you like.

You keep moving the goal posts rather than admit you're wrong

"oh oh, the MOT centre will fail it" nope. They can only do visual checks

"oh oh, VOSA will be upset" nope. They closed down 2 years ago.

Well said

Not that he'll accept it.

bigjl this is the only reason that you can fail a vehicle on fitted with a dpf ( A catalytic converter or particulate filter missing where one was fitted as standard)

I await proper proof

Have a read of Section 7.1 of the MOT Inspection Manual

https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/429032/mot-inspection-manual-classes-3-4-5-7-vehicles.pdf

Section 7.1 Exhaust System

Method of Inspection - check the presence of catalytic converter(s) and particulate filter(s)

Reason for Rejection - A catalytic converter or particulate filter missing where one was fitted as standard.

Its just a visual check on DPFs like it is on Catalytic Converters.

It takes a dealer 30 seconds to ask what sort of journeys you do and say this won't work for you.

Unless there is a written proof of this, dealer can wash their hand saying "yes we asked that time but customer's life style changed later".

Buyers should be always aware what they are buying! You are not paying dealer for their "advice" (unlike a lawyer whom you pay for advice) - you are only buying a car from them.

Is the airbag present on this car or not?

The airbag warning light will indicate if there is a problem with airbag.

Problem with catalytic converter will be indicated by "check engine" light. It is an offense to remove those bulbs to hide these problems.

In fact if such warning bulbs don't light up and goes off when engine is switched on it indicates a problem with respective systems.

You're missing the point i was trying to make with the pictures - you cant tell by looking at those whether or not the contents are in them.

As an aside though gutted catalytic converter may not throw on any error lights, and if it did throw on an engine management light, thats not a fail anyway.

Likewise with a faulty or removed airbag, there are ways it can be wired if you are unscrupulous to resolve the light coming on - either devices you plug in instead of the lighting, or fake the wiring in the dash.

But as i said, thats beside the point - for all three of those devices, there is only a visual check for their presence, and in the case of the latter two, there may be further visible indicators of them being missing or faulty - but they cant go pulling your car apart to prove the actual mechanism itself is in there.

There are some other interesting things you can do at MOT - for example, if you have a spare wheel in the car, it must be road legal, so if theres doubt, remove it before you go.

Engine management lights on are not a fail - unless they specifically say or relate to a tested system - eg an engine management light on and flashing "ABS Failure" will be a fail.

Yes, exactly. Its hard to prove unless its in writing.

However, its not unreasonable to ask for the salesmans advice - its part of what they're there for. My FIL had a Renault Modus which he loved (well somebody had to!) and he went to change it. We went in to the salesman in our local multi franchise and asked what he'd recommend and he said a new model Nissan Note. He got one out for my FIL, he took a drive in it and loved it. We'd never have otherwise have thought of one.

Heres one of the devices i'm talking about, freely available

"Your car will no longer be able to pass MOT with the airbag light on dash. Simply just removing the bulb won't work anymore, as it will have to be shown working when you turn on the ignition, and the airbag light has to go out once the car is started. The good news is that my bypass module will fix this problem, simply just Plug n Play and your car will pass MOT without additional problems."
