Cooler temps and short trips are what cause the sludge to form. If you see sludge and moisture under the oil cap, I would prioritize this over the DISA, unless that is showing signs as well.
The DISA rebuild is a good thing to do as well. Glad you have already got the cooling system done. Those three things (DISA, CCV, and cooling system) are all the major threats to the M54.
Glad to see another manual transmission X on the board. This car is quite the unicorn and only becoming more rare.

Sorry for the ignorance, but what would I be looking for under the oil cap? Is it that mayo like substance that I see clog up the CCV lines? Or just general dark sludge is a sign too? I will need to check the oil cap soon now!
I know there is a hose from the valve cover to the CCV but I'm worried on breaking the potentially brittle plastic to check on the state of sludge and then having to replace it all anyways

Appreciate the tips, fingers crossed I can bring this car to above 300k+ miles! The shifter does feel just a bit on the sloppy side, but I'm not sure if that's how they feel, or if I need to look into rebuilding some of the shifter parts.
