1. Inspection Panda 4×4 Multijet

First good day to all – is my first entry I have a Panda 4×4 Multijet BJ 2009 new car since Sept. 2009. Now I was at the first inspection after 22000 km: cost point 230 Euro (Austria/Tyrol) – changed oil, oil filters and also air filters and pollen filters. I am interested whether this corresponds to the prescribed performance at the first inspection (for example, after 30000 km only oil and oil filters were blown at our VW)? Where do I see the oil filter, did not feel the I have to unscrew the aluminium protection below or can I get there differently? I want to check if there were original Fiat parts installed, with the oil no Selina was used (at least a sign with another brand hangs in the engine compartment).
