Not a query for a change, I thought I'd post this in case it helps someone else!

I have a 2004 E500 with the M113 engine and thought I'd do an oil change. I found the location of the sump plug online, bought a couple of new washers along with the oil and filter, then set to work.

With the car on axle stands, it is NOT possible to get to the sump plug without getting fully under the car. Personally I didn't feel it was worth the risk so put the car down and used my Pela 14 via the "dipstick" tube.

So, my advice is that if you have the car up on a 2-post for something else, do a full oil drain whilst you're at it. Otherwise, do the very easy oil and filter change from above.

The same will be true of the M112 V6s and the AMG M113K.

just get the car on stands, get under the car and get on with it ;O)

I did the transmission oil and filter under there too on my 129 and 215, may as well

Possibly I'm a big girl's blouse as my jacks and stands have never failed in years of spannering, but entrusting the 3D-ness of my head to £30 of Screwfix's finest axle stands is still off the cards smile
For some reason, having it dangling 7 feet off the ground feels safer lol
I had the tranny fluid done by the garage last year, how was it as a DIY job?

I Have the M113 V8 in my SLK55 and can appreciate this post. There are two sump plugs and getting to the rearmost is a concern on axle stands

O/P - I used ramps from Halfords, far more secure and I believe a 2 tonne weight limit, more than enough.

I too have one of those Oil/Fluid siphon devices and used it in conjunction with the drain method. There was barely a drop left when I undone the drain plugs, so I assume the route of the siphon tube from the dipstick pipe is pretty much at the bottom and back of the sump once the car is up at an angle.

There was more mess for me in replacing the filter, blood thing was full of oil and dribbled everywhere !

Just done the oil change on my newly purchased E500. Wanted to use the siphon pump that I have but there is no dip stick or tube fitted to my car so had no alternative other than to borrow my brothers 4 post lift. Would not fancy doing it using axle stands.
Bit odd that Mercedes did not fit a dip stick to my car when earlier and later versions are fitted with them?
How do the technicians drain the oil when servicing the cars? Mine is further complicated/made more difficult because it is fitted with a sump guard.

The siphon tube has a red cap, and it's possible yours has been lost... Odd, as red normally denotes transmission.

Open the bonnet, look to the aft of the engine on the driver's side. The tube is about 1cm diameter, pointing vertically up.

I have a tube with a red cap on it at the rear of the engine but, I am pretty sure that this is the transmission oil dip stick tube.

Which gearbox do 211s of that age have? If it’s the 7g there is no dipstick, it’s filled from beneath, with the level set by allowing it to overflow over a weir tube. If it’s the 5 speed (722.6 I think) the cap is black but a red locking tab normally denotes the fluid has been changed - a black tab is fitted at the factory, with replacements being red. There won’t be a gearbox dipstick if it is a 5 speed, an overlong “workshop” dipstick is used to check the level.
