I usually put back what I take out. But, the filter holds some amount. Any idea how much?

 

Ugh I can't find that thread, forum members had a very in-depth discussion on the oil offset value on the datacard.

It was in the W212 sub-forum with lots of information but I can't find it anymore I checked my bookmarks, everywhere.

It would had been easier if the like button works again, it haven't worked for me for a long time. To show appreciation and to express gratitude yet when I need the information again I can find it through the post I liked but that feature has been broken for me for who knows how long and there are so many posts I want to like to show appreciation yet I can't because the feature doesn't work.

I ended up commenting to express gratitude through words instead I guess that shows my sincerity so maybe the like button broken isn't a bad thing.

 

I always measure my engine oil with engine being OFF at least 4 hours, usually overnight engine OFF is my most common test.... the next day.
Our oil filter is the self draining type and located high up, so it does make a difference if we measure oil level too soon after engine OFF.

I too sometimes wonder, does my MAX level at the red plastic tip dipstick is 6.5 liter +0.6L already calculated by MB , or what ?

I think the oil dipstick is generic say for M278.820, what they can adjust is the dipstick tube length, based on the engine set up/variant/car model.
S class S400 with M276.8xx uses front located diptick and the oil pan maybe different than mine. My E400 is using rear azz located dipstick.


Let me trace the Dipstick and Dipstick Tube combination. My engine is M276.820 and M002 ( turbo ), M008 CKD and M104 ( engine increased performance) codes.

I think the dipstick tube below is for rear azz located ones only.







Maybe those I wrote in red are front located oil dipstick. Let me check one of them.







M276.822 is also an azz located oil diptick, but uses different DIPSTICK TUBE, but same Oil Dipstick as my M276.820






Assuming my oil dipstick FULL mark is not yet compensated by 0.6 liter, by me always keeping it at FULL LEVEL based my oil dipstick ( 12 hours engine kill ),
I guess I am safe enough to be within the 1 liter LOW LEVEL to FULL LEVEL.


BTW, on yachts marine engine, dual engines. Oil dipsticks are measured/marked manually during engine commissioning by the engine brand.
Say target fill based on the engine type and oil pan type is 30 liters, they will fill up the engine oil to 26-28 liters and make a hole at dipstick as LOW and fill to 30 liters and make a hole again
at the dipstick as FULL.

You see marine engine is a bit angled when installed , it is that way for the propeller shaft attack angle.
Also some yachts are using V drive gearbox, thus engine FRONT can face yacht rear/stern.
If using normal straight gearbox, engine FRONT is facing yacht front/bow.
So the use the oldie proven method of marking the oil dipstick with 2 holes based on actual liters of oil filled.

Left/Port and right/starboard engines are also using different oil dipstick, because on dual engine yachts , the oil dipstick tube is located in mid-way or inboard side
of the engine, so engineers can access it easy as the middle of the engine room is usually the main walkway....unless very big yachts.

Can anyone point out where the X26 no 4 connector is on my 3.5 V6?

 

I have an engine like yours. I will check tomorrow to be certain, but I think the connector is maybe under the manifold just behind the oil cap. My problem was with my M276 bi-turbo. But I also have the M276 NA in my C350.

Somewhere in this area...

 

Hmmmm, I could be wrong. On the M276 bi-turbo engine, the X26 connector is well in front of the oil cap. So, on the NA engine, it may be under the intake tube going from the air filter to the throttle body. The connector is one of the larger ones and is gray.


X26 on M276 bi-turbo

 

Love this light, btw. I have one also from Harbor Freight.

 

3.5NA does not have X26 up to number 4 on the engine. 3.0 Turbo has it.
3.5NA X26 is up to number 2 only. See attached wiring diag for ur engine.


This is X26 #4 on 3.0 Turbo



This is the physical unit X26 #4 on the engine, 3.0 Turbo. At bank 1 ( right side ) at aftercooler coolant bottle.

2 units, one black and one grey. Male + female.

It appears that in the case of the M276 NA 3.5L that the wiring harness goes directly from the S43 (Oil Level Sensor) to the ECU at pin 56. There is no intermediate X26 (or equivalent) connector.

If you wanted to disconnect the S43 for reset purposes (and not sure that would do it), you would have to do it at the oil pan.

 

Please note, when I "solved" this error by testing for continuity (see post #67), I also had added some oil. But I had also been messing with the IC. The combination of things may have caused the warning message in my car. Since I put the IC back to what it was and did the continuity check, the message has not returned in over 8 months.

 

With the complexity of these engines and systems, understanding them is beginning to require an electrical engineering level of education and knowledge to understand.

 

Good thing I have a General Engineering degree with a concentration in EE. Of course, I got my EE before electrons were discovered. Now, I can only spell "EE".
