If your changing it because it’s not filling, there is a service kit for this type mind (Part no 5027 86 59-00/3) which means you don’t have to change the IWMS.
If you do need to change it, it’s a pretty straight forward job. Take off lid, side panel, front panel under door. Disconnect inlet hose and inlet valve cover. Remove the large plastic nut holding the IWMS into the tank cavity.
Remove side tank screws and the IWMS will just pull off. Disconnect valve/hoses from bottom of tank.
Re-fit new IWMS and away you go.
