Service costs XC90

Good evening, everyone! I bought an XC90 diesel from a Volvo dealer in the southern NÖ, Mödling, and I am very happy. Today the car came to the obligatory service at 20000 km. Before the service I have still not filled the storage tank of the washing machine up to the go with disk cleaner. In the evening I brought the car and see: 1 lit disc cleaner by 2.64 0.5 lit cooling liquid by 1.95 filter insert by 13.80, seal by 1.56 and filter by 52,– Euro, beside oil, plugging on winter bikes and rental car in total at least 519,14 Euro. If I had not filled up the disk cleaner, the rest would not have occurred to me. The mechanic said, when testing, the guys in the workshop certainly consumed a liter. Can I in a year at all 0.5 lit KÜhlfluid plus Wassser lose? If then the dealer is still close because of the opinion computer, what should I keep from a workshop, which rented me by 35 Euro and when the transfer says: Sprit is still able to leave the station or leave the station?
