Abstract:
A method pertaining to an SCR system in which reducing agent in liquid form is supplied to a feed device (230) and via which feed device reducing agent is supplied to at least one consumption point (250) from a container (205): the steps of continuously detecting the feed pressure (P) which the feed device (230) furnishes, and controlling the operation of the feed device (230) on the basis of changes (P′) in the feed pressure (P), with the object of reducing the impact of unwanted air supply at the feed device (230). Also pertaining to a computer programme product containing programme code (P) for a computer (200; 210) for implementing a method according to the invention. Also an SCR system and a motor vehicle which is equipped with the SCR system are disclosed.
