Car Tax - Vehicle CO2 rating

[tamtoot]

Good day.

I've just checked my Car Tax V5C and note that my CO2 rating is listed as 139 (140 DSG) whereas my 2.0 TDI Sport is supposed to be 170 DSG...and as shown on the VW sales invoice etc., so car tax rate paid was 100% less than that required. The car was taxed by the dealer before I took delivery...

I'm just about to send off an email to VW but wanted to know if there is anywhere on the vehicle that I can confirm this rating to confirm if I have been done over by the VW dealer...on either the tax payment rating, or the engine fitted to my car!!

Your info is welcomed.

Thank you
