im going to guess that its a breather of some sort, but have often wondered the same myself. The top part unscrews. I wondered if it was a diff breather for when crossing deep water but could be totally wrong  2003 BMW M5 - 5 Litres of V8 Optimax Slurping Goodness in Carbon Black

I’m sure it’s for getting the engine oil out with a pump. Andy.

It’s on a bayonet fitting and is for vacuuming the oil from the sump. Great way to change the oil, it takes about 5 mins to suck it all out with a good vacuum pump and 10 mins to complete the job with new filter too.

Some people feel removing the sump plug gets more oil out, it doesn’t this way gets just as much.

PS the oil needs to be hot.

Yeah. Look at ideal place to put some sort of stick down with markings on it.

Not sure anyone mentioned it being an ideal place to put one but something is better than nothing  2003 BMW M5 - 5 Litres of V8 Optimax Slurping Goodness in Carbon Black

You can see where the pick up point is once your under it. it's next to the sump plug so will extract all but the smallest amount of oil. and as we don't flush the engine oil then what does it matter if a small amount is left....
