DIY: E400 Oil Change (From Bottom)




This is the best way to do it, of course takes slightly more effort than just from the top.
This is also very similar to the non-biturbo M276; I believe that the oil filter is slightly offset.
Some mods coming soon...stay tuned.




This is one of those things though that either way really works. Mercedes has the nice convenience of the oil filter at the top,
so you don't have to get underneath if you have the vacuum.
Then you can zip these off and on quickly. I usually set the torque down low and drive the home. Driver also comes in handy for torx screws like those securing the air filter housing and various interior panels. I use a Makita 12V driver [FD06Z] since I have Makita tools in general.

But what I also do when I do my own is (1) sacrifice a quart of new oil as I’ll drain the oil, put plug back in, fill with ½ quart fresh, wait a minute and then open the drain again and pour the rest of the quart in to the point of seeing it come out clean from the pan. You’d be surprised how effective that is to help
flush out the old hiding in the corners of the pan.
The other thing I’ll do (2) maybe once every 25k miles - pour about a cup of Seafoam into the old oil, let the car idle for about 20 minutes to circulate, then let it sit for an hour, then start the drain/flush process as noted above. I’ve done this technique for at least 20 years now ranging from Lexus, Mazda, Toyota, VW, and MB - always amazes me how dark and dirty the oil comes out. The car seems to idle more smoothly once the new oil is in as well.

The M276 NA oil filter is in the same position as the M276 TT shown in the video.
Agree with the benefits of bottom drain. The biggest hassle is removing the underbody shields, and the electric or pneumatic driver is the way to do it. On the W166 GLE the rear shield needs to come off first for the easiest overall procedure.
