Okay so I have a 2014 c300 w204.080 with the m276 engine. On this engine the oil filter cap is upside down and when it's removed leaks oil all over the front of the engine.
Am I not doing something correctly? Is there a way to change the filter without the oil mess that I'm missing?

That is NOT the engine oil fill cap! It is your oil filter.
Changing oil on the M276 is easy and clean. You vacuum out the oil through the dipstick tube, THEN remove and change the oil filter. Your oil cap is on the top passenger side of the engine.
My M272 has a similar filter cap, just not as long. I unscrew it slowly and any residual oil just drips down back into the housing. I'll lift it up just a little then set it back in for it to drain. I think the vacuum from it being sealed may keep some oil in the filter, until the seal is broken and unscrewed. Dont just unscrew it and lift it right out, let it drain.
If I remember correctly I do the filter after I suck the oil from the dipstick.
I use a 12v fluid suction pump. It takes awhile but does get almost all the oil out, the oil has to be warm or else it takes foreverrrr. I got it so I can store it away in a little box, instead of finding room to store a large device like above. But if I had room or more vehicles I would probably get one like above.
I modified the pump by splicing on a 12v plug then run it off a converter plugged into an electrical socket, instead of running it off my car battery.
I was thinking about getting this adapter so i can use a larger diameter hose. Maybe if my current hose breaks ill justify buying it:

Every Mercedes that I've had over the last 25 years has an oil filter similar to that. Try changing the oil after the car has sat idle over night. Drain the oil first. Then after doing that, open the cap and keep a shop rag nearby to catch any drips. If changing the oil before the car is run for the day isn't possible, let the car come up to operating temperature. Then drain the oil. Let 15 minutes pass and then change the filter. That amount of time should let the oil drain back down into the sump from the filter.

READ your owners manual.
I think it's you who needs to read the post again. I know it's a filter and I called it that. I don't suck out oil I drain it and want to drain the filter without the mess.
Very good ideas thank you all for the input. I think maybe I'm changing it to quick and it don't wait to long before removing the filter so. I'll be more patient and be sure to drain the oil first.
Y'all are awesome thank you again

Ha! You're right. I thought you wrote "oil filler cap". Looks close enuff to "oil filter cap" to be easily confused. I'll blame it on my new glasses.
Vacuuming oil through the dipstick tube is the prescribed method for extracting the oil. However, you can always climb under the car and drain the oil the old fashion way.
As said, drain the oil first from engine..oil filter housing near empty then. You can actually fill the engine via the empty oil filter housing if you want.
Will recommend lifting the dipstick up first if going the traditional bottom drain method because of the vacuum even when the oil stops dripping down, if you pull it then it will starts to drip again.
As other forum members mentioned, changing the oil is such a breeze on the M276. Long live the dipstick, even WIS calls for dipstick extraction so I actually don't recommend going from the bottom other than occasionally dropping the splashguards to check for leaks.
Please kindly see the attached WIS document, the same document MB tech follows to change the oil on the M276.

Thank you. I am going to have too try and sick it out and see which way I prefer.
The info is great thank you again
Using the dipstick i have to go for a drive to warm the oil, get out the pump and run my extension cord to power it, have two empty containers ready to collect the old oil, stand there while the pump is on to make sure its not sucking air, then when done leave the pump hanging in my basement overnight to let all the oil drain out of it completely.
Using the drain plug just drive the front end up my ramps, then mess with the undertray screws, unbolt the plug and let it drain while im changing the filter, then just have to deal with wiping the oil collection pan clean after dumping the old oil.
When I replaced the oil filter housing gaskets I did both methods because I was worried I may have gotten coolant in the oil. I sucked it out first then the next morning I opened the drain plug just to be sure everything was out. There was hardly any oil that came out, dribbles. Just wiped the pan clean with a rag there was nothing to pour in a container.
Side note be careful if your looking on FCP for drain plug gaskets, for mine at least it shows the wrong size gasket. The correct gasket is 14mm.
Thank you again TimC300. I just bought a bag of crush washers after having my oring leak on my filter housing. Three crush washer was another thing I've been neglecting to replace on a regular.
The % mark-up on the washers is a bit much. Its only $4.40 at the local MB parts dept. FCP prices are up there, sometimes more expensive than the MB dealer for small things like nuts and bolts.
I bought a bunch when FCP had them on clearance for only 13 cents previously, I happen to be ordering stuff anyways. Then i'll add a few Mann oil filters to the order.
If someone didnt know the Mann filters come with an "extra" small o-ring that fits the top of the W204 dipstick perfectly. Seems this o-ring is included because certain Mercedes models use it in the filter housing.
I finally came across the instructions showing where the o-ring on the filter cap is supposed to go.

Yes you are correct. I have the long filter housing and the paper element that goes inside that has a plastic tip that had a small o ring on it. Mine is the M276 engine. Tho it does look like the plastic tip serves no purpose the o ring hole in there engine isn't drilled for oil pressure I don't believe.
Mann oil fter? I use three top of the line wiz. I trust your opinion TimC300 so I'll have to look into those to it's about time to but mer some more stock

I use the suction method, you can change oil & filter in church clothes. The filter I just lift it slightly, then take it off.
-I spilled two times oil filling it up where the funnel slipped, luckily not much. I everytime forget to modify the funnel not to slip.
My Izuzu is worse even if they neatly provided a catch arearea around the filter on top of engine, if you spill the oil runs through a tube to the ground, the secret here is just lift if off few mm, let it drain back in engine and then lift off the filter and rubber and replace it.
