The invention is directed to a CO2 sensor-cleaning arrangement (100) for cleaning a sensor (101, 103, 105), wherein the arrangement is adapted and the sensor (101, 103, 105) are adapted for being implemented in a vehicle (1000), in particular for supporting a sensing function for an advanced driver assistance system (1500) of the vehicle (1000), and wherein the CO2 the sensor -cleaning arrangement (100) comprises:- a CO2-reservoir (104) comprising pressurized CO2, in particular as a pressurized CO2-gas,- a connection tube (106) connecting the CO2-reservoir (104) to a nozzle (108); and a control valve (114) arranged in the connection tube (106) and configured to control a flow (F) of the CO2-fluid from the CO2-reservoir (104) to the nozzle (108) in the connection tube (106);- wherein the outlet (108) is arranged and configured to provide a CO2-medium (110) to a surface (112) to be cleaned of the sensor. According to the invention it is provided that- the outlet (108) has an orifice (116) configured to generate the CO2-medium (110) at least partly in the form of CO2 dry-ice particles (110) from the CO2-fluid and- the sensor cleaning arrangement (100) further comprises a heating element (118) arranged and configured to controllably heat the surface (112) of the sensor (101).
