Nice video!
I prefer to open the filler plug first to make sure it can be unplugged, otherwise you end up in a terrible problem when refilling. Another advantage in doing that is that with the filling plug open you don’t get all this spraying.
Finally, if you really want to go by the (Mercedes) book, you should clean the plug (in fact replace it) and put a drop of Loctite on the threads.
I agree with most of these but how many people are going to order new plugs when the old ones are perfectly fine you know what I mean... I would definitely skip the Loctite because you will never open this plug again afterwards. Thanks 👍
@@projectathosNew plug would definitely be overkill - I agree, but Mercedes will disagree on this, they sell the plugs..😄..a drop of Locktite…probably not absolutely necessary, but okay if you want extra security. In that case “soft” locking will be fine I guess.
Thank you for responding to my thoughts & keep up your good work!
thanks a lot for showing this.
I have the same car and i have a strange noise or humming from behind.
after closer inspection it seems that the sound is coming from 1 side from the differential.
I have already replaced the bearings and checked whether the tires are not cupped.
In the maintenance history I see that the fluid was replaced 2 years ago.
My question is ..have i a differential problem or if the axle from differential to the wheel is not well
What's the mileage of the vehicle? Usually the humming sounds come from the differential and you can check the fluid inside just to make sure. Otherwise one side only would be a bearing most of the time. Cv Axle just on one side would be strange and I have never seen this... Best thing to diagnose would be with the vehicle up in the air on a lift for a mechanic to use the sound magnifying tool that doctors use called stethoscope and listen for the noise source. Also check the suspension completely on the side where you hear the sound. Another thing could be the actual driveshaft going to the Rear Differential. And lastly I have had cases when the tread of the tires have made very wied noises sounding like metal grinding or humming so check those and that has nothing to do with cupping. It's only in the thread and how it runs on the pavement creating noises due to the rubber resistance... Thanks and good luck 👍
@@projectathos174000 miles or 280000 km
I drive 220D bluetec
The weird things is that it humming on speed between 40 and 60 miles
The tires i have already change from front to back and visa versa.
This is not comming from the driveshaft because i have already inspect that with a gopro session action cam.
And i have remove the rear seat and listening carefull and the sound is comming from one side and not in the middle of the differential.
So yes it could be the bearing from the differential of one side.
But can you explain why suspension could cause the problem?
thank you in advance
@@projectathosIt appears that the noise is coming from the tires. I have already serviced the differential myself, but it hasn't made any difference. I also lifted the car and tried to reproduce the sound at high speed, but the sound didn't occur again. Therefore, I suspect that the tires are the cause of the problem. Additionally, when I drive on a brick road (Dutch roads) , the sound is not audible. This is likely because the road's surface smooths out the tire irregularities, preventing the sound from being produced. Upon inspecting the tires, I noticed irregularities on all four of them. Hence, it must be the tires causing the issue.
