emission max value?

[legepe]

Hi all
I have a berlingo multispace 2012 (taxi) just failed test on emissions (0.51 max with fail value of 1.49)
The car was always (occasionally) showing message "Risk of filter clogging" but it used to pass tests
Even though diagbox was telling me it had a regen 160 miles ago, and was averaging regens at 257 miles I did a manual regen today, and took car for a proper blast.. no light or message of fault no matter how hard I tried to get it to come on!
So, sofar so good..!
However, the other thing I have realised! is that the sticker under the bonnet for its emissions max value of 0.51 is possibly off a newer vehicle, as it was front end accident damaged when I acquired it, and the part where the sticker is may have been changed. Ive looked in the log book to see if it tells me, but I cant find anything, apart from the section V.7: CO2 (g/km) which says 139 G/KM. Called local citroen dealer, but they cant help either! does anyone here know, how or where to find this information?
Any advice much appreciated

This has been taken from the mot testers information regulations.

Thanks for the reply/info casaerica!
This is a taxi test which is quite a bit more stringent to normal tests (every 6 months) and they now use the number thats attached to the vehicle (under bonet just in front of bonnet catch - see attached) - I believe that this part of the vehicle may have come from a 15/16 plate berlingo
In my log book in section V.7: CO2 (g/km) it states 139 G/KM for my berlingo which does not equate to 0.51 at all so I guess there must be a conversion/calculation to get it, or maybe another way?
If it turns out that this part of my car is from a newer model, and therefore the number on it does not relate to my vehicle - I guess I will have to prove it to the test station for them to accept it!

The 139g/km is for CO which is not tested on a diesel, only a smoke test. The limit of 0.51 would be the value of the opacity (or the light from the sensor which is lost) but without your factory VIN plate there's no way to tell. Officially vehicles made after 2008 should be as above, 1.5

Ive looked back at previous test results and it seems to me that it depends on what side of the bed the tester has arisen from! but regardless, they charge me 54.50 every test.. n if it fails then its another 54.50 I have to pay! I have to find a way to prove what is the true value on my berlingo. I will call again! citroen with the vin number, and hopefully they will tell me this time!

As Zion has said, it is opacity test, so how much smoke the exhaust produces. Can you post a photo of the emissions fail sheet with the numbers as I got confused with your description of 0.49 max and 1.49 fail. The test limit on yours should be 1.5, but they have applied 0.5. That happens, I had similar (https://www.berlingoforum.com/thread-18853-page-3.html) limit of 0.7 applied although it should have been 1.5.

As above, if you could re-post the test results that would be helpful. Also, FYI, there's a default value that they apply if there's no sticker, so you may want to remove it if it's wrong.

I think the rules are that if there's a sticker , that's the level they measure.
