Adblue Control module replacement

[tommylux]

Hi, I have an issue with my Adblue fuse taking up 3A constant draw. I’ve unplugged the fuse (it wasn’t easy, since they’ve tucked the fuse right in the corner). A SEAT dealer said that the only thing on this circuit is the Adblue module, 3q0941329. Does anyone know how to get at this thing to replace? The only thing I can see is this VW Passat YouTube video here:

but it seems to differ and struggling to work out how to take the trim off.

I appreciate any support.

Thanks
