TFSI AXX blue smoke on long idle

Hi guys,
Bit of a weird issue, but when idling a long time (5+mins) I start to get plumes of blue smoke out of the exhaust.

I get no blue smoke on startup, on boost, or any other time. Car doesn't drink excessive oil at all.

When it happens, if I rev engine/drive off it stops immediately. Happens with engine hot or cold.

I have front PCV delete from CM without catch can.

Anybody shed any light on this lol? Servicing is bang up to date, last service only about 3 months ago.

Car drives spot on, no power loss. Had someone follow me and they saw no blue smoke at all.
