Creaking BCD...

Try cleaning your seatpost and clamp and just inside the frame and then put a spot of grease on the post if its ally, nothing if its carbon unless you got some carbon paste lying around, and check the saddle rails clean and grease and or spot of oil on the rail entry points, also clean the handlebar clamp and put a spot of grease there as well, try checking your pedals as well, leave your BB until the last and even try removing and giving all faces a good clean and finish with a spot of grease on the faces, its a process of elinination.

I strongly recommend not using super glue on any bicycle bolts.

I have the same crankset and had the same problem with it. There are 3 options:

1. Go to your LBS and borrow their tool, or buy one of the tools (they're not expensive)
2. Get that large flat blade screwdriver, or file down a coin or washer to fit across the indentations. It doesn't take much to stop it moving.
3. remove the bolts completely, clean carefull behind the inside portion and then put a couple drops of super glue in there so it gets held firmly in the seat when you do the front part up.

In my case it was a couple  of the bolts that were loose, and option 2 solved the problem.

Self loosening crank bolts are fairly rare. Once you start fiddling with them or changing chainrings though...

As per advice above: check qr & levers are tight and fully locked, ideally take them off and give them a lube. This is a really common cause of noise which is seemingly coming from the bottom bracket/chainset area.
Check seatpost is lightly greased along the whole inserted section.
Check your bottom bracket is running true. Grab the cranks and give them a wrestle from side to side across the axis of the bike. There should be no play whatsoever.
If you can unship the chain check the rotation of the cranks for free running ie no unusual noise or grinding feel. You can do the with the chain on, but it harder to tell.
Clean and lube all pedal interfaces including greasing the pedal threads and torquing up to manufacturer recommended tightness.

If it's still creaking after you've done these, let us know.

Try a spritz of GT85 around the bolts - if that helps, it could be the bolts. If it doesn't, try spraying the pedals. Oh, and check your seat post is well greased - sometimes you think it's the crankset when it's not.

So it's  an allen key at the front and a slotted nut at the back?

In those circumstances I've just used a dinner knife form teh kitchen draw. The blunt thin blade works perfectly.

Its just to stop the nut from turning when using an allen key.

For what it's worth, just check the front rear quick release mounts and apply a dab of grease. ..... This solved my creaky bb noise, after I'd pulled it apart

   Park do the CNW2, similar to the BBB tool, managed to misplace it when I really needed it, got a screwdriver type one from Evans, I think, similar to the Icetools one, Evans now do the FWE one which does look even better.  There are some advantages to the screwdriver type, and it is never an easy job, the extra distance your fingers get from the pointy chainrings is good.

    If you run a triple it's almost guaranteed the bolt will be behind a tooth of the granny.

  My XTR M970 uses floaty light Torx T30 bolts, so I need 2 tools for the outer bolts.  And from personal experience I know the inner bolts love to crossthread.  Progress...

There's a special tool required. I'm not sure if this is specifically the one you need, but if not, you need one very similar to it
