Abstract: A tank for motor vehicle includes a tank wall, a fill opening, an outlet opening, a plurality of functional components, and a plurality of attachment formations. The tank wall forms an outermost casing of the tank. The fill opening passes through the tank wall for inlet of operating fluid into the tank. The outlet opening passes through the tank wall for outlet of the operating fluid. The plurality of functional components are designed for pumping and/or for cleaning and/or for detecting a property and/or for changing a property of the operating fluid. The plurality of attachment formations are designed as being integral with the tank wall for positioning of a plurality of functional components on the tank wall. The functional components are disposed on segments of the tank wall, which are arranged at an incline to each other.

Abstract: A motor vehicle operating liquid tank, in particular for storing aqueous urea solution, with a tank shell surrounding a tank volume and with a tank opening extending through the tank shell, wherein a planar heating device in the tank volume is provided with an electrical resistance heating track arranged sandwiched between two plastic films that oppose one another in a planar manner and encase the resistance heating track, the plastic films opposing one another in a planar manner and each have a layer of compatible, thermoplastic plastics at least on their surfaces facing one another which are connected to one another locally at least along a seam track surrounding the electrical resistance heating track, wherein slot areas are provided inside this seam track in which plastic film sections lie opposite one another in an unconnected manner without the intermediate arrangement of a section of a resistance heating track between them.
