The tube is sticking out of the diagram over towards the air filter housing. So....it's in front, on the left of the engine as you face it.

The tube is back is indeed the trans filler tube. There is no dip stick inside it.

so on a 2003 E320 facing the car it should be on the left hand "passenger" side torwards the front? and the back left hand side next to the firewall is the transmission correct?





red oil?

blue transmission?

The tube is on the passenger side of centerline, towards the rear. The tube has no dipstick, (as reported earlier). The TRANNY dip tube has a locking plastic cap. You have to destroy part of it to get it open. In addition, it cannot be seen or accessed without removing the large plastic double air filter housing. The oil tube cap is black and PLAINLY visible with the filter housing in place. I have a 2003 E320. Unless someone previously removed the tranny cap and failed to replace it with a new one, you cannot mistake it for oil because it must be unlocked (destroyed) to get it open.

Can you take a picture?

(the saying goes, "it there are no pictures, it doesn't exist!")

This photo is incorrect for the W211 vehicles............both tubes are in the back of the engine...........the oil is visible, as indicated, on the passenger side with a cap on it.......it sticks up and visible. The trans tube is to the right and lower of the oil tube and hard to see without removing air filter housing.

This must apply for the gassers. The car in question was a gasser but just to clarify that this is not the case for all W211 engines, at least the 211.026 has the engine oil tube differently positioned.

Well since everyone has given you everything except the one thing you asked for, here it is. A photo of my screwdriver with the tip hovering above the oil fill tube on our 2003 E 320 GAS engine

Yup that's it. The transmission is more rectangle with red tang on top with a warning that says "MB workshop". To remove it you break off the red tang push it down through the cap then remove the cap.

For the oil cap on the dip stick tube it will just pull off.

I change oil in my E500 all the time the first times I drained and just refilled with correct fill.

Last time I bought the mityvac and did the job in about 20 min including the filter change. No more crawling under to pull the plug for me on this one.

While we are sharing information, I want to relay (again) that the large "O" ring that fits the filter stalk needs to be placed according to the diagram that comes with the filter (Mann anyway). I rolled that ring all the way to the very top groove of the stalk and lost 2 quarts of expensive oil for my trouble.
I have no explanation for my actions except that I was experiencing a "weak" moment that comes more frequently with age. It is an easy job if you pay attention to what you are doing. The cup that houses the filter is much easier to pour oil into than the filler tube. I really never bother with the filler tube unless I am trying to second guess the oil level sensor with my Chinese dipstick.

Easy for you to post the photo when you already have the car and don't have to buy one to take a photo.

Yeah, I have to admit, I thought someone more eager to demonstrate their knowledge than I, would respond. After lurking here for several years, you just get a feeling for the kind of people who need to stay away from the internals of their cars. (Not necessarily someone asking a simple question). If I win the lottery or if I was making $400/ hr advising or healing people, I would never even pop the hood, but since my time is cheaper than the dealers, I do what I can.
