1995 Transit Turbo Diesel Emissions Label

[alexb1406]

Hi, can anyone advise what the emissions value opacity should be for a 1995 turbo diesel automatic. I know the default value is 3.0, but the tester has used the figure on a little sticky label next to the VIN plate on the passenger step that says 'Ford' and '0.98' and nothing else. Is this correct? Of course, it failed, but he is insistent that this is the correct value. My argument is that a vehicle of this age and without a DPF cannot be expected to meet such stringent standards, so that is not an emissions label. Previously this has been tested to the default value which it passed. I have attached an image of the VIN with the label next to it. Can anyone please clarify whether that is an emissions label.

all i can tell you is what google says

A 1995 diesel vehicle build plate typically corresponds to the Euro 1 emissions standard (introduced in 1992 for cars, or phased in around 1994 for light commercial vehicles/vans), though some vehicles built or registered later in 1995 may lean toward Euro 2 (which formally took effect in 1996/1997).

What to Look for on the Build Plate (VIN Plate)

• Smoke Opacity (K-value): Diesel build plates often display a designated smoke absorption coefficient (measured in m⁻¹), sometimes written near a 24 R marking or inside a dedicated box on the VIN/manufacturer sticker in the engine bay.
• Manufacturer Limits: During an MOT or roadside check, testers use either the specific smoke limit stamped on your vehicle's build plate or the default statutory limit for the vehicle's age.
• Euro Status Text: Older 1995 plates rarely spell out "Euro 1" explicitly in words; instead, the standard is determined by the vehicle's type-approval year and date of first use.

Emissions Standards for 1995 Diesels

• Euro 1 (1992–1995): Set early limits for carbon monoxide (CO), combined hydrocarbons and nitrogen oxides (HC + NOx), and particulate matter (PM).
• Clean Air Zone Compliance: A 1995 diesel vehicle is not compliant with modern low-emission or clean air zones (such as the London ULEZ or UK Clean Air Zones, which generally require Euro 6 for diesels) and will typically incur daily

Thanks Mark. That's very useful and I appreciate you taking the time to answer, but what I can't find anywhere is whether that little label next to the VIN plate is actually for smoke emissions. I know the MOT tester's guide says the emissions plate 'may' have a sticker saying '24R' - which I believe refers to some Regulation 24, but my MOT tester is having none of that, he says that is the emissions sticker and has to be 0.98. Of course that will never pass at that level.

Can anyone tell me what that sticker is? And, is there an emissions marker anywhere on that VIN plate? I don't think there is.

this search brought up the answer

and it does say that little box is saying 0.98 metres minus 1

with the words

ford transit "0.98" emissions sticker

cant reproduce that search here as the Colons will be gone .. and they matter in the search


hmm wonder what the mot guy would be doing if you ripped that sticker off ? as if was never there .


BTW no idea what to the power of minus 1 means, as dunce here , never did A level maths

Thanks Mark, but that link just takes me to Google. Can you see if you can find it again as I'll be interested to see it
I am going to rip the sticker off. I can't imagine a 1995 Transit being able to meet that level.

The minus 1 is metres to the power of -1. It can also be written as 1/m. It is a measurement of opacity - that means how much soot is blocking a beam of light through the exhaust smoke. I'm not sure of the detail but that's basically what it means.

Before ripping it off make a close up photo. Crop and straighten it and upload it to a reverse image search engine. Maybe there’s something to be found. If nothing keep the photo for reference, rip it off and clean the area so it’s not visible it was ever there. The MOT inspector may have access to historical data on the van. Wouldn’t worry about it being there. Maybe some previous owner stuck it on from another vehicle.

yes i know what the minus 1 is supposed to mean .. but not in this context

yes the link takes you to google

below that link in that post is the search words to use

ford transit "0.98" emissions sticker

i done it that way because ...; was getting broken link when i posted it, as google reproduces the colons in the search as plus 2 % percent or something like that .. that wiil not work here

This is what you get if you put those search words in

On a Ford Transit, the "0.98" on the vehicle's manufacturing plate or sticker refers to the manufacturer-specified smoke coefficient (opacity value) for the engine.
Here is exactly what this means for your vehicle and its MOT test:

What the 0.98 Value Means

• Engine Opacity Limit: The number 0.98 represents the smoke density limit (in m⁻¹) determined when the vehicle was type-approved.
• MOT Testing Threshold: During a UK MOT test, if a diesel vehicle has an official manufacturer plate value displayed on its vehicle VIN plate or an engine bay sticker, the MOT tester must use that specific value as the legal limit for the diesel smoke test—rather than the standard default limits.

Why It Matters

For older Euro 4 or Euro 5 Transits, standard default MOT smoke limits might be higher (such as 1.5 m⁻¹). However, because Ford specified 0.98 on your vehicle's plate, your Transit is legally required to achieve a cleaner smoke reading of 0.98 m⁻¹ or lower to pass the MOT diesel emissions test.

Where to Find It

This number is usually found in a small box in the corner of the VIN plate (located either on the door jamb or under the bonnet) or on a dedicated emissions control sticker inside the engine compartment.
If your Transit is failing an MOT because its emissions are hovering between 1.0 and 1.5, this specific "0.98" plate value is the reason the tester is failing it.


Big tip coming up from me

During the test the mot examiner increases revs to the max aloud

AI
During a UK MOT test, a diesel engine is revved to maximum engine revolutions (revs) or the rev limiter to check that the governor works properly and to measure exhaust smoke opacity

ME

What this does, you've been driving stop start .. small journeys etc .. during the past year, soot will accumulate in the exhaust system and adhere to the insides of it.. mot tester does so above .. loosens it all and the results will look like smoke... when really its crap off the inside of the exhaust. the instruments see it as smoke .. the mot tester sees it as as smoke they are fooled,, even brown rust dust will be interoperated as (particulate) Smoke, YOUR CAR FAILS

What you should do the day before mot... find a wide road up long steady hill where you can give the van maximum acceleration and maximum throughput through the exhaust...... clear all that crap out before it gets cleared in the mot and causes failure.

Thanks Mark

I will have to remove the sticker. The van has been off road for three or four years so I can't take it for a blast up the motorway. In the past it has been tested to the 3.0 1/m standard and always passed with flying colours, both with this same MOT tester and the previous one where I used to go before I moved here. This time - I think he's swallowed the MOT guide from DVSA - and insists it has to be 0.98. I haven't got the report from him but I think it was somewhere between 1.2 and 1.5, so as you said a good blast might do it, but without tax or MOT it would be difficult.

Thanks for all your effort though

[metalworker0]

off the road 3 years !..is ideal opportunity for the inside to have rust powder over every surface .. and that's a particulate .


get thumping on it with a big rubber hammer

Somewhat off topic, but I remember a Jaguar old-timer owner. Beautiful classic, however to pass the emissions test an air compressor was installed to blow more air through the exhaust to dilute it out. Not sure exactly how it worked but it would pass the test.

That was on the V12s around the mid-70s, I worked on many of those. I'm not sure of the chemistry behind it but it was required for the American market and was later introduced to the European maket as well.

Peterr, that was an air injection pump, not a compressor, tbf.

[Peterr]

That makes more sense
