Parasitic draw from AdBlue heater

[Chubb123]

Hi everyone, I have a parasitic draw on my T6 battery. Now found the fuse causing the draw c43 looking to be the ad blue heater? Can anyone help with this?
Since I unplugged this fuse the draw on the battery has completely gone down. Any advice would be great please. Thank you
