2014 CRD GU Fuel Filter Sensor Plug

Hi All,

Its been a long time since ive been on here due to illness and its great to be back. Now this Is embarrassing as Ive worked on these plugs many times over the years. But for the life of me i cant get the plug off the back of my Fuel Filter, Seriously think Ive lost the plot.

Ive removed the bolts and turned the filter upside down and cant believe the struggle im having with this OEM plug.

I Notice there are two sections to the plug and I would suggest that it is the first section (brown) plug that comes out. The pic shows the bottom of the filter and the plug in question

If this button is the black one on the middle bottom of the brown plug then im stuffed cos it wont budge with a small screwdriver or my Hardened scribe.

Can someone please help me out and confirm Im not doing anything wrong.:icon_bonk:
