CO2 on vehicle registration higher than Parkers guide

vfairbrass

I have recently purchased a Vauxhall Corsa SXi CDTI SXi 5d with the specific intention of having a car in VED band B (road tax £30/£35). On Parker's guide all versions of this car are in that band with CO2 emissions under 120. Yet the vehicle registration document has CO2 as 127 putting the car in Band C with consequently higher road tax..
What is the procedure for querying this with the DVLA?
Is Parker's guide incorrect?

No need to query it with the DVLA because they will use the data supplied by the manufacturer (which will probably have to have been tested in the UK to be verified).

It is 127 as shown on the Vauxhall website.

Edit, just tried the link, which isn't working, which I got to, by going to the Vauxhall website and then to the Corsa and picking your modle and then specifications.

If you do that it will show you the tech specs and confirm 127.

Vauxhall have 2 versions of the 1.3 diesel engine. The 65ps version is 119g/km and the 90ps is 127g/km.
The 65ps engine is in the "Life", "Breeze" and "Club" trim levels and the 90ps is in the "SXi" and "Design" models.
