Government Bulls**t !!! They want us off the road ! My 1998 T4 low mileage 74,000 Pendle chipped has just failed it's mot on emissions, vin plate states 0.7, the mot reading was around 1.7 so easily a pass as the limit is 3.0 but because VW have stated on the plate 0.7 it's a fail. 0.7 is equivalent to a 2014 vehicle ! T5's are having similar issues. You cannot simply remove the sticker vin plate either as it flags up on accessing an option list for the emissions part of the mot. I've left my cherished bus with a well trusted garage for a new fuel filter that will have an additive added and also the fuel tank with a good scream down the road and hopefully it will pass!
As much as I love VW's cheers for adding the 0.7 limit to the vin plate !!!!!!!!!!!!!

An update, I got a mot pass finally ! Emissions test results with a 0.7 1/m test limit applied were 0.31 1/m before that another fail 0.82 1/m with the same test limit applied.
I'll find out exactly what additive was used and there unfortunately was a few hard runs up and down a dual carriageway !
Apparently removing the vin sticker will work as long as there is no remanence to avoid detection, then the test limit applies to a default of 3.0 1/m.
Hope this helps, I don't find much response on here, perhaps it's all been said before but mot emissions tests have very recently changed and I'm concerned for future of our beloved diesel transporters..
Cheers K

Unfortunately not scratched Off is classed as defaced or illegible, not clear enough to read. You still will have a stamped vin number so all is good

Np but just to be aware whatever decision you/we make DVLA will move the goalposts, so please research removal of vin sticker before you remove . Please remember romove very carefully, avoiding damaging paint work etc, cheers K

There were few threads related to the May 2018 new MOT emission conundrum, but I’ll comment here as this is the most recently active thread on this matter.

I had my MOT today, a confident pass with a couple of things which were already rectified (number plate light bulb and advisories on stiff brake load sensing valve). The MOT centre did not provide the emission test result (they don’t give out anymore?) so I don’t know what the value our T4 reached.

I echo the comments previously made on the VIN plate value; vehicles should easily produce a value under the maximum smoke value (absorption coefficient) presented on the VIN sticker. If it doesn’t then there is an issue which needs attention. If a vehicle is smoking, regardless of the colour, then there’s something that needs attention.

There are few easy things that I did and probably attributed to emission pass (and most likely very subjective opinions!).

  1. Fuel pump timing: A VW dealer garage or independent specialist should be able to get the fuel/air ratio and timing correct. For example, I went to a local specialist and got the timing perfect for £50. No more white smoke and hesitation in cold mornings. In fact, no more smoke whatsoever.
  2. Regular servicing: Make sure the vehicle oil and filters are changed at regular interval (every 6 months or 6,000-8,000miles whichever comes first). Approximately £50 or so from EuroCarParts (with regular 50% discount codes) and basic DIY skill, or £100 (I’m assuming? Never asked a garage to do oil change) for simple oil change interval service at any garage. Always get full service and MOT together.
  3. Use premium fuel: (Shell V-Power or BP Ultimate) every other or third tankful. Or every time if you are rich enough!
  4. Additives: Alternatively, trial fuel additives such as Diesel Rhino (cheaper than premium fuel in the long-term) every tankful, or Liqui Moly Diesel Purge straight into a new fuel filter.
  5. No short errands: Avoid <5mile short runs or stop-start town driving. Drive the van long enough to reach optimum coolant temperature each time (won’t take longer than 10min). Any journey shorter than that should be done alternatively by foot or cycle (I acknowledge this is not suitable for everyone).
  6. Excercise: Do a good long run on Motorway, also known as the “Italian Tune-up”. Once the vehicle is up to the optimum coolant temperature, drive down a long stretch of road (Motorway or straight dual carriage way are ideal) at the appropriate speed limit (60-70mph) on 3rd of 4th gear (aiming at 3,500-4,000RPM, occasionally rev to just under the “red line” on the gauge) for 10miles or so. Allegedly, this works the engine and heats up the exhaust system, “burning” or “blowing” out the soot accumulated inside the exhaust. Make sure the vehicle has the chance to “cool down” by driving normally for 10-15min or so after.
I’m not a vehicle mechanic, engineer, or performance specialist so my knowledge is only as good as a fellow car enthusiast. But in my experience, these are few easy actions worth getting into habits to maintain the vehicle well.

Happy motoring!!

At the moment if you fail, remove the sticker and get a test at another garage. Currently they have to test as presented and it will default to 1.5 for T5 after mid 08 and 3 for prior. Make sure you remove the sticker carefully so if the goalposts are changed you can put it back. Additives and cleaners will reduce the emissions so will the Italian tune up. Dont let it run stationary for any length of time prior to the test. If you fail on emissions yes you probably have some issues but only if a good blast and additive doesnt bring it down to the "plated" level. Lots of short or city stop start driving will cause debris/soot etc to build up.
