Neither is wrong, despite the apparent contradiction.
For 2009, there is a very little-understood "staging" in band K for vehicles that are in band F currently. For example, the auto V6 at 238g/km is in band F. However, if it had been registered later, it would have been in Band G, and vehicles in band G will go directly to band L or M (do not pass go, do not collect £200). Band F vehicles can not be grouped higher than K for 2009, regardless of ending up in L or M in 2010. This is the bit that the BBC have missed (and that the DVLA themselves are confused by).
In other words, because it was band F, the galant V6 auto will be in band K for 2009, DESPITE the CO2 output being appopriate for it to go into L, which it will do for 2010. This is shown on the parkers page where you got the info above.
