I could be wrong about the pollen filter. All I know is that when I look at the price list I acquired, the labour charge difference between a full service and an intermediate service is another £80. However, it doesn't mention a pollen filter. The extra costs on parts appear to be for: Air Filter, Axle Oil, Coolant, and Transmission Oil all of these items adding another £100. Either way, I saved a bit by not having a full service.
