2. Inspection 9-5: Are these costs normal?

Hello, had our Saab 9-5 Vector 3.0 TID for the 2nd inspection (EZ 10/05) at almost 40,000 km. Costs: net 517 Euro (total 616 Euro). I find the costs quite heavy, because there was nothing to repair. What is actually part of the regular inspection scope? In addition to the actual inspection and material the following services were calculated: 0.3 hours. Change fuel filter 0.4 hours. Change interior filter 0.1 hours. Change wiper blades The old wiper blades funkttio In fact, they were replaced for 23.58 nets/pieces, among other things, washing system addition 5l for 14,95 nets, engine oil for 113 nets. First of all, thank you for your opinion.
