1.2 TSI (CBZB) turbo oil drain pipe

1.2 TSI (CBZB) turbo oil drain pipe; anyone have any advice on removal?

Quite surprised to find that it's put up a big struggle on our Roomster. (Posting in Fabia2 cos it's likely more folk will own and have tinkered with this on Fabias).

Removed the single screw from the clamp plate on the block end of it, and both ends wiggle about, but neither wants to pull free.

Have tried quite hard, although not with the best leverage with car on axle stands not far off the ground.

I guess the o-rings have aged and baked hard?

Worried about busting the pipe and rendering the car undriveable by trying too hard, so have ordered a spare, but just wondering if this is a common experience with turbo oil drains generally, or on this particular set-up?

I'm only wanting to check that it isn't blocked. 😁
