I am about to do my first oil change before the A service. I got everything from the dealer this time and was told besides oil and filter we need a one time use screw plug. I can't see where it goes. Has anyone done an oil change and knows where this plug goes. Part number for the screw plug is 000-990-95-18. I have not drained the oil yet and think it may allow additional oil to drain from somewhere. It holds a lot of oil 9.5 litres but if I don't get all the oil out I risk overfilling with no dipstick to confirm. Also interesting that the oil filter is on the bottom of the engine and there is no dipstick. The engine is a M176 but the block, pan etc. shows A177 AMG. AMG and 177 are all over the engine and components.

Screw plug for oil change and a random red rubber cap found sitting in the bottom pan cover

Note the AMG A177 on the M176 engine . Oil filter on the bottom and no dipstick so no more oil extraction . Scanning the QR code just gave me a very long number.

Got this off the WIS for the 176 engine. The metal plug there is what the drain screw is according to the document attached. The document also does not call for a one time drain plug like it does for the GLS (it actually says "new drain screw"). Someone please chime in if I am wrong, but it seems like the drain plug you got from the dealer is not correct for GLS 580 engine.

The dealer got back to me and admitted he thinks the screw plug is not for this application and that the oil filter may be wrong too. They are sending me another filter and we'll see what the correct parts are when it arrives in a day or 2. Further investigation on this I found that this screw plug to drain the oil was used on the 2018 and newer S560 and has since had recalls. My dealer said I am the only GLS580 they sold and service so far and we didn't get the GLE580 in Canada so they are not as familiar with the parts. I thought if you plugged in the VIN you always got the correct parts used on your vehicle.

To complete the story for a GLS580 / M176 DIY oil change with actual part numbers - it's confusing! Also most of the Mercedes parts sites do not yet include the 2020 or 2021 GLS580 in their parts finders. Pretty annoying.

All you should need for an oil change on the M176 is the correct spec oil and an oil filter (which comes with a new o-ring) and a new crush washer for your drain plug.

The service sheet attached to this post up higher in the thread says the M176 motor in the GLS580 requires 9.5 liters of approved engine oils but doesn't list the spec required.

Mercedes on-line fluids finder does not list any required specs - it just says "Approved engine oil specifications, please see operating instructions of the vehicle or contact a Mercedes-Benz service center." . https://bevo.mercedes-benz.com/bevol...arspecid=11887

The 2020/2021 GLS580 owners manual indicates Mercedes spec 229.61 oil will provide the lowest fuel consumption and 229.52 spec oil is also allowable. As above you need 9.5 liters.

Going back to the Mercedes Fluid Finder, I see two fairly exotic looking 0W-30 oils available meeting the 229.61 Spec.
https://bevo.mercedes-benz.com/bevol...229.61_en.html
LUKOIL GENESIS SPECIAL MD 0W-30 - Maybe useful if you live in Russia...
Mobil 1 ESP LV 0W-30 - https://www.mobil.com/en-ro/passenge...-1-esp-lv-0w30
The Mobil part number for Mobil 1 ESP LV 0W-30 is 154313. Searching for Mobil 154313 this finds a few on-line sources in Europe, nothing obvious in the Americas.

It's much easier to find 5W-30 oils meeting the 229.52 Spec.
I've been using a 229.52 compliant Motul oil in my daughter's BMW for several years. At $49 for 5 liters it's reasonably priced ->
The Mercedes part number for the oil filter is 1761800800 and it costs about $25. It includes the filter and a new seal.
It looks like Hengst makes the oil filter for Mercedes, Hengst 1761800800 is also available online for about $15.
The Mercedes part number for the drain plug is 000000-008789 and it costs about $3. You shouldn't need to replace it.
The Mercedes part number for the drain plug seal is 007603-014106 and it costs about $1; any 14 X 20 X 1.5 mm copper crush washer should do

Torque specs are:
Oil filter housing -> 25 nm
Drain plug -> 20 nm

I hope the above helps. Others does this agree with your research / what your dealers are telling you?

I got feedback from the dealer and they don't think the screw drain plug is for my application after all, and they are not sure of the oil filer so they sent another filter from the dealer today in case. I drained the oil and removed the filter which is a real mess flowing oil over the filter case even though the crankcase drain plug already had 99% of the oil out. The second filter the dealer sent me was identical in size and shape but had more fins and was made of a different material and I am sure it would fit. The original factory one I removed is the same as the first filter the gave me so I installed that. Part number 176 180 08 00 and number on the filter is A133 184 00 25 matching the one I removed. I think the second filter with more fins (therefore more surface area) would be better but since I don't know if the flow rate is the same I won't use it until I can confirm that. The oil I used was at the MB dealer at a lower price after my MB club discount $12 CAN/litre or convert to approx $9 US for the Mercedes brand. They only had 229.52 in 5W30 and this dealer has not seen any 229.61 oil yet. I can't find 229.61 in North America and was not aware it promotes increase fuel economy. When I reinstalled the fuel filter which used a 24mm socket I noticed on the filter housing case a picture of the case and 25.5nm beside it and a picture of the drain plug and 5.2nm beside that. When I torqued the drain plug 5.2nm it didn't seem like enough so I gave it another 1/16 turn. Checked for leaks all good. I see you gave a spec of 20nm so I am glad I gave it a little more. Why does it show 5.2nm - it must be that screw plug for another model? So I filled it with 9.0 litres so I would not overfill - not enough. Ended up adding the extra half litre and it still shows down a half litre on the dash but I read you need to drive it for 30 min to get an accurate read. I miss the good old dipstick! Got it out and drove for 30 minutes and reads full MAX with the 9.5 litres. Now I just need to get the maintenance monitor to reset. I have not found a way that works for the MBUX. I tried a method from another model for MBUX but it did not work for me so still looking for a way to do that. On my last MB when I did oil changes and reset the maintenance computer it automatically selected the next A or B service so when I did an extra oil change it went to the next service so I had to keep track of when "B" service was really due and not rely on the maintenance computer. I hope the MBUX is better and recognizes more than what oil spec you used.

Note the filter material and increased fins on the bottom one

I measured the openings both ends and each filter is identical. Right one is what is on the 580.

Hood and doors closed, engine off, vehicle on - push start button foot off brake.
Go to TRIP menu and must be at mileage screen ie total miles and trip miles.
On the steering wheel left side for both buttons Hold the back button for 1 second and immediately hold the track pad down also and hold both for 5 seconds and release
Go back to main menu scroll from TRIP menu left to the WORKSHOP menu
Scroll down to ASSYST Plus and follow directions from there. Start the engine, go to Full Service, then to Confirm Service, Confirm engine oil grade used enter and Confirm service was done.

I don't know what the service numbers mean that come up ie. Service 1 and Service 3 but I just scrolled down and entered service completed. confirmed the oil grade and accepted to reset.
Now it automatically assumes my next service is a B Service after this initial oil change but I plan to do the A service next when it is 1 year old and estimated 15000kms at the dealer. I will ask if they can specify which service A or B at that time will be in the computer for the next service interval. Hope this helps as I tried many methods off the internet before I figured this method worked.
If anyone finds a better or more streamlined way please add your comments.
Also if you know what would happen if you entered at "Service 1" or "Service 3" what that would have done - please comment.

Thank you so much for the write up!

I came across your post as I was looking to change my oil on my 2018 S560 which seems to have the same M176 engine. I saw the oil filter location but not the oil drain plug. It seems the bottom of the engine has an additional covering that loops under the engine. So I'm not clear how to remove this extra lining. It seems to be made of a sturdy fabric that perhaps just needs to be just pulled off and then I should be able to see the drain plug. Did you have this extra lining/covering?

marchgroupinc

Yes it has a plastic cover over the engine. Remove 8 screws around the perimeter and it will drop down after you shift the cover forward slightly and exposes the entire engine area. You will see the drain plug there. The oil filter is up top of the engine not accessed from the underside.

Denis Osullivan

I’m with you on that plate you’re referencing but after removing that one there is another cover over the bottom of the engine. Look like a type that absorbs oil- some type of fabric- not plastic.

marchgroupinc

My GLS does not have that.

Good to see guys doing there own maintenance still. I just changed mine at 3,700 miles and really enjoyed the time, looking at changes to the 167 chassis etc. Also the oil did not look terrible (no sheen), but was really dark for only 3,700 miles. For me going to 10k is not an option despite what the experts say these days. Its kinda like brushing your teeth, cant hurt 4 times a day!
