This is a complete, genuine Tire Mobility System (TMS) kit, often included as an alternative to a spare wheel in VW Group vehicles (VW, Audi, Škoda, SEAT). The kit contains an "ELEKTRISCHE LUFTPUMPE" (Electric Air Compressor), Part No. 8P0 012 615C (made by Active Tools, 12V, 15A, 180W), and a bottle of Dunlop Tech TMS Tire Sealant, designed to temporarily repair a punctured tyre for limited use until a full repair can be made. The entire kit is stored in a black zipped bag with the part number 2K0 601 703 printed on it. This is an essential safety item for compatible vehicles and appears to be in excellent, likely unused or very lightly used, condition, based on the packaging and overall appearance.
