Before I bought the car, I was under the impression that the 1.9Tdi Roomster was in tax band E.

When I actually went to see the car and purchase it, it was on band F. I've now paid for the next year on it and it definitely is a band F, but every reference I can find to it points to it being a band E. For example, from Parkers website:

1 Sep 2006 - 1 Dec 2006

£135.00

F

149 g/km

1 Dec 2006 - 22 Dec 2008

£120.00

E

139 g/km

My logbook and sale papers have a first registration date of June 2007, and it's an 07 plate.

Is this correct? If I should actually be E I'm more than happy to keep the F rating with its higher CO2 which will mean less MOT emissions test worries.

The tax banding published is for a standard car usually, if you add optional extras then the banding maybe affected due to increased weight especially if the car was close to the boundary to start with. This is why the greenline does not come with a spare wheel, nor can you specify it as a factory option.

I suppose so, perhaps it was just a marketing ploy? As though I've run the codes from my sticker and it comes up with roomster 2 spec, no added options, having an advertised CO2 of 139g to get into band E is only 1g below running into band F?

That said, the printout from my last MOT was so poor I can't actually tell what it was, other than that it passed. So perhaps I have one of the 2006 ones that sat at the dealer unregistered till 2007....?

The CO² banding for your car will be printed on your V5. Like you said, perhaps it's an older car that was in stock before being registered.

CO² levels do not get tested at the MOT. That's for CO and hydrocarbons.

The CO² levels against a car are from the standard EU test where they drive the car on a rolling road through simulated environments and collect the amount of gases from the exhaust. Generally they are no where near the amount that actually comes out in real life driving.

Got the bill today. £135. Sure it was £120 2 years ago. Certainly £130 last year.

Does that then mean that the CO measured is a separate entity than the road tax CO2 figure? So i'm not aiming to achieve a CO2 output of below 139g, for example?

Yep carbon dioxide is what your car tax is measured on.

The MoT checks for levels of carbon monoxide, which you get from incomplete combustion.
