I fitted a new pollen filter yesterday, and believe me it is not a black art. It took all of 15 minutes from start to finish. It will take 5 minutes next time, so simple, you just need to be a bit dextrous.
My filter had been fitted back to front by the factory, not good attention to detail, it must have been either a Friday, or else they have a Brit working in the Polish factory.

Will carry out the rest of the service next weekend.

I fitted one the other weekend too - piece of cake. I got down there expecting to have trouble, but the cover came off easily and the new filter slotted in with minimal trouble. I'm not sure if the 1.2 is the same as the 1.4, but the air filter and plugs take ages for what are usually easy to change parts. You'll enjoy getting to the plugs ... don't stretch any of the cabling while your trying to work out how to get the coil packs off...
