HELP!!!! BMW Dropped bolt into engine!!!

Is there any way of taking out a bolt from inside oil pan without removing the oil pan? What happen was, I was replacing the CPS ( crankshaft position sensor )and my dumbass accidentally dropped the bolt into the CPS hole. I heard it hit metal and went under the car and pounded on the oil pan and heard the bolt rattle .. I know it's a b$#@% to remove the oil pan , so that why I'm trying to work around that.. I already drained the oil hoping it would miraculously come out but No Luck !
So is there anyone who can help me out with some good ideas . TIA

The bolt is carbon steel and magnetic, so one of those tools that is a magnet on a flex cable might get it?

Sometimes the drainplug, but it is not factory standard that I know.

For an experienced wrencher, dropping the oil pan is no big deal. I can tell you this, the oil pick up tube into the engine has a mesh screen on it. It wont get sucked up from there rest assured.

From Napa, they have magnets on long wire springs. Insert into the oil drain hole and fish around and you might get lucky.

Onesikda9.....here's what your oil pan looks like in the pics below. You can try removing the VC & try to fish out down the front of the engine with magnet. If it is fact all the way to bottom of oil pan, and not on the timing chain, you might be ok. It could possibly move toward the engine & deep part of the pan & you might be able to fish it out. You could also try to remove the oil level sensor & try to fish out from there with magnet. I'm just not sure what baffles or other stuff might be in the way.

Good lookin out brotha! I thought It would get sucked up if starting the car.. I haven't tried starting it for that same reason.

Drain the oil, remove the oil condition sensor, large hole to fish a magnet into. Buy a gasket to reinstall the OCS.

People forget that the OCS is a pretty large hole. Look at the oil pan pic above.

Remove the oil level sensor, and drainplug, spray a ton of brake clean into pan area and drain it all out, then try fishing around with a magnet around where you hear the bolt.

To OP, if it is 100% confirmed that it ends up at bottom of oil pan and not stuck between any moving parts, then it may work to just leave the bolt at the bottom of oil pan(until next oil pan job), provided there is filter/screen that prevents the bolt from sucking up by oil pump.
