Car tax higher ?

For almost 3 weeks now the Zafira Life M Tourer (2.0 177ps automatic) has been in my possession. Today the letter/deed from customs came to the motor vehicle tax collection… What surprises me is that for the Zafira 392€ annually is estimated. Everywhere on the Internet the 366€ per year is due. Although it is only a small surcharge, nevertheless the stated CO2 emissions of 196g/km, which also stands in the vehicle certificate part 1. This is also for every gram what about So in this case 101g x 2€ = 202€ (CO2 tax) + 190€ (hubspace tax) = 392€ total. Does someone happen to have a Zafira Life with the 177Ps machine and can I confirm the amount or is there an error with me ?
