So wish that I had a clear answer on this. This question applies to the m275.980 amg engine.

Does anyone know what the the Dyno Mode Oil Level is supposed to be when full?

Also, does anyone know what level in mm the dipstick tool is supposed to be at for this engine?

In WIS, the system shows between 22 and 48 mm if I remember correctly, for a m275 non-amg, which I can guarantee is completely 100% wrong. Firstly, the engines I believe have the same oil pan and the capacity differences in the AMG and non AMG lie in the oil cooling circuit. Secondly, the Mercedes tool does not register a level below 50mm.

Any help is greatly appreciated.

 

On my '05 CL65, fully topped off it reads 123mm on my MB dip stick.

Thanks for the reply,


Just curious if you have a chance to check, what does this correspond to using the dyno mode menu to test oil level. 9.5?


Thanks

 

Wanted to see if anyone can check. Does your electronic reading in dyno mode show 9.5 qts when full in morning?? I see that in owners manual it says that our cars have capacity of 11 qts so I want to make sure programming didn't screw up this high low for me.

Right now if I have over 9.5 like 9.6 showing it says overfilled reduce engine oil. I though that's before I did programming I saw over 10 qts.

Thanks for the help

 

How do you see the Dyno-Mode oil level? Than i can compare.

When I remember correctly in WIS there is no figure of how many mm you have with Dipstick for the M275. We searched some years ago for this figure. And there were different oil pans with SL, CL, S when I remember correctly.

 

Thanks, yes WIS does not say what the level is in MM. However, as long as I confirm what our digital display should show in dyno mode, then I can confirm what a cl65 oil level is in mm when full. As discussed earlier in this thread, at 9.5 qts in digital display, the dipstick tool is at around 123mm. But I need to double check that 9.5 qts is correct for full.

Also, in dyno mode secret menu, use arrows as discussed below and you can fully disable all electronic traction and stability control (not that you would want to on the road), this is used during dyno testing as the front wheels are stationary.

Dyno Mode Oil Level: Best when left overnight, must be level ground.

With key in position 1 (not ready to start), go to the instrument cluster menu with odometer mileage display. Click the reset button (to the right of the cluster) 3 times quickly in succession. When you do this correctly, the vehicle voltage will be displayed in the cluster. Use the up down arrow to cycle to a menu that shows oil level and has two dashes (it will not display yet).

When you get to this menu, then turn key to position 2 (not starting though), wait for few seconds and the oil level will display. Depending on where you are it will show liters or qts.

Let me know if you have any issues and thanks again for checking.

 

Just FYI, Dyno mode is best for drag racing too, especially if you have installed a line lock.

 

Any idea what yours shows for oil level on this screen cold in morning level ground?

If I can confirm that yours shows around 9.5 or below and that it is not higher, then I can work out what the dipstick tool should read as well as confirming the star mm reading.


Any help is much appreciated.

 

Hello, sorry for the late answer. Today I had the time and checked the oil level in the display.

It showed 8,0 Liter = 8,45 US Quarts which I think is the same amount for refilling at oil-change with filter change.

Display says Oil Level is O.K. This is in the SL65. I hope this helps.

 

I'm out fishing in Prince William Sound so can't check for you. I'll try and remember to try it when I get back home.

 

Thanks for checking. EDIT*** unfortunately the SL65 has a lower oil capacity of 8.5 quarts as vs 11.0 quarts for cl65


M275 AMG Oil Level Spec
Dyno mode oil level=??
Oil dipstick mm reading= Will confirm
DAS Star Reading MM Engine off (cold ast overnight level ground)= Will confirm (found in actual values under some menus shows this mm reading)
DAS Star Reading MM Engine running at idle warm= Will confirm (found in actual values under some menus shows this mm reading)


Edit** had to erase data as didn't realize that the previous data was from sl65 and this is different than cl65 oil level.



Thanks for checking this.

 

When the message comes to fill in 1 liter of new oil, I will read the level in the display to doublecheck and post here.

 

I just realized that you have a SL65 and this changes things. According to your owners manual, the oil capacity is 8.5 quarts or 8.0 liters. The owners manual for S65 and CL65 show oil capacity of 11 quarts or 10.5 liters.

So this data will not be accurate here. Maybe someone else can chime in when they can for S65 and CL65 models.

 

Man, nice relaxing time. Would appreciate it if you could check this for me. I can put together a nice data card here for future reference on oil level. There is a menue in DAS where oil level can be read in mm as well.


Look forward to hearing back.


Enjoy fishing

 

Hmm, interesting.

I know at oil change with filter change they use 8,0 Liter of new oil for the SL65. But I don't think that everything from the whole system comes out with that, e.g. oil coolers, hoses etc. So I assume the SL65 has also more capacity than 8 Liter in the whole system. But I will try to find more info.

When I remember correctly the S and CL has a different oil pan than the SL, because of different subframes or something like this...

 

great info. especially the dyno mode setting. checked yesterday on an 04 cl600. 8.4 quarts. it showed errors for i believe esp and abs. turned car on and i believe the oil was 5.4 quarts. not exactly sure, but the abs and esp malfunctions were still there. the car was turned on but i was not driving. are the errors shown because i wasn't driving the car while the dyno mode was set? went back to regular settings and no malfunctions. any info. on this?
thanks, harv

 

You get the ABS/ESP malfunctions because they are turned off in Dyno mode. Normal.

I'll check on my 600 as I don't remember what it showed on that menu last time. I've always seen 9.5qts and with that done at an oil change it's always withing the "ok" reading on the dash, but I agree it would be nice to have an actual correct fill level. This automatic, non dipstick system seems counter-intuitive to me.

 

thanks for the info.

 

It would be nice to know for comparison what the 600 runs because ours is supposed to have more capacity.

One thing I have down for sure is das mm reading at idle hot engine level groun: 65 amg and 600 are same level-it's what is in pan that is being measured.

If any of you have seen the wis document for oil level reading you will notice it says 22-48 mm. Guess what it shows in das???

Oil level running engine on hot level ground: 22-48mm

This would be same for amg 65 and 600.

So one reading is confirmed.
Question now is whether level cold off .

Thanks for everyone's input

 

Changed the oil yesterday, going slowly to verify all the readings through DAS and through DYNO mode. I spent way too much time on this but given that I seem to have a good grasp on the system, I figgured I would share it with the community and possibly help someone else that is dealing with the same dilemma...how much oil is in the car.

If anyone has different results please chime in as it would be helpful.

After completing these are the results.

Drained oil and filled-After going slowly I ended up putting about 10.2-10.4 quarts of oil in the engine.The following are the readings verified through DAS adn Dipstick. Also, the main oil check shows "Engine Oil OK" at this reading. No overfill.

M275 AMG Oil Level Spec
Dyno mode oil level= Mine 9.4 (ASSYST AT +1) Between 9.2-9.7 depending on settings in Assyst. see below.
Oil dipstick mm reading= 130mm with rigid dipstick tool (engine oil above 176f after driving and shut off and sit for more than 5 minutes on level ground)
DAS Star Reading MM Engine off (range 50-77mm) = 74mm (oil above 176f and sit for at least 5 minutes after shutoff)
DAS Star Reading MM Engine running at idle warm (range 22-48mm)= 52mm Will confirm (found in actual values under some menus shows this mm reading)


Notes and Info:
MAIN OIL CHECK: Per Owners manual, the main oil level screen should be checked with ENGINE AT OPERATING TEMPERATURE sitting at least 5 minutes level ground after engine turned off. If oil below operating temperature then wait at least 30 minutes.
DAS MM READINGS: these readings do not indictate min max in the normal sense like a dipstick. The max and min in this case are the values when the computer will WARN you that you are at Maximum oil or at Minimum oil. Therefore, the high value can be used as a full reading albeit so long as you follow the requirement that oil is at operating temp. However, the low MM is the point when you are at MINIMUM OIL LEVEL i.e. where there is a warning in display that your engine miust be shut off to prevent damage to the engine. IF you see it this way, we have a huge reserve of oil before there is a danger to the engine. I calculated as I filled, how much the DAS MM changed as I filled oil. Basically, every 8 mm change is 1 quart. So the range of 22-48 mm when engine running means that from a maximum fill, you would have to be down 4 quarts approximately before there would be engine damage. Now of course this depends as the reading may go way down when your cornering or accelerating for example. But does give you perspective why mercedes has even a 2 quart down warning and how this still doesn't hurt the engine.


IMPORTANT**Dyno Mode: This is more of a reference level and can be programmed. The final level depends on the ASSYST settings in das under "Oil Minimum Warning". This setting defaults at 0 and can be adjusted between -3 and +3mm. The positive settings are used if "oil warning is activated too early" and negative for "oil warning activated too late". I adjusted these and checked all the above values nothing changed accept the DYNO MODE OIL LEVEL READING. This screen in ASSYST is used by technicians when they change your oil. The system is very cool actually as it measures how many refills you have had and how many quarts of oil you have used during the ASSYST period. The ASSYST settings reset these when oil is changed lets say at the dealer. Therefore, the setting of the "Oil Minimum Warning" can be coded by the dealer when changing oil. Mine was set at +1 when I first entered the system. These values are useful for measuring oil usage and calso can be used as a reference so long as you know what ASSYST setting you have. I have 9.4 when full. So if I lose oil and am down to 9.0 I can add about .4 and I know where I sit.
These were the resulting changes:
ASSYST 0=DYNO MODE 9.2
ASSYST 1=DYNO MODE 9.4
ASSYST 2=DYNO MODE 9.5
ASSYST 3=DYNO mode 9.7

Therefore, the value that is shown in DYNO MODE relates only to the DAS ASSYST setting. None of the DAS mm readings changed when this value changed. Because the ASSYST is in control of warning you of oil level, the way the system works is that the engine computer sends the mm signal from the oil level sensor to the instrument cluster which calculates based on the mm reading what the quarts are. The instrument cluster settings then decide whether you have too much or too little depending the settings which include the variant coding of the engine type. It seems that the default for our vehicle is a full reading at around 9.2-9.4 on the dyno mode. The only thing the assyst does is take this reference value and then as the oil is subtracted, it compares and sets warnings when the value goes down.

Without knowing which setting your car has it is impossible to know what that reading corresponds to as far as the DAS mm reading and the Dipstick reading. Prior to resetting or changing any adaptions at all on my car, my ASSYST was set at +1. My dyno mode level at +1 with the fill I have detailed is 9.4. If I change it to 0mm on Assyst, it goes to 9.2.

I know this may be a bit much but it killed me not understanding what oil level is best. It seems the system is not very exact and is more concerned with the range.


Best

 

Thank you. This is very good input how the system works.

I want to add : When my system says in the display to fill in 1 Liter or maybe 2 liter of new oil, I only fill in 0,5 liter and wait if the warning goes away. If not I fill in another 0,2 liter and so on.

So there is no chance of overfilling and what I read in some owners manuals if you always fill up to the max. there is a chance of getting a higher oil consume in the end.
I can give no reference numbers, but it seem to be true, when the car manufacturers write it in their manuals as an advice for the owner.

 

I understand your reasoning and I can see where the concern might come from. There isn't any problem with doing it your way because the system is a huge reserve system and just warns you when its getting low.

The only thing I will add, is that according to the manual and WIS, when the display tells you add 1 or add 2 you are supposed to just put in what it says. The reason is that the system does not measure in .5liter increments. An illustration as example: when your system says "add 1 liter" it may actually be down 1.4 liters. However, the system won't tell you to add 1.4 and wont tell you to add 1.5 until its 1.5 down. So, you fill .5 liters to system. Now you are at .9 liters down. However, the system doesn't read in increments so it will say "engine oil ok".

There really is no harm in doing it your way like I said, because the system can have between min max difference of 2 liters and this is a huge reserve. If on your particular car you get less consumption like this then no reason to change. Just at least know that the system will always say "engine oil level ok" so long as it is not 1 quart low. anything in between will display ok.

All in all I really like the system actually. Its more like an airplane system with a huge reserve in case you lose some oil. Its very safe even wen oil level drops.

 

My CL600 showed 8.4 on the display sitting for a few minutes after driving. Running drops to 5.5 or so, under hard accel it goes down below 3qts. It's interesting to watch the level increase as the car sits after shutdown, there's a lot of oil draining back down inside that big engine.

 

Thanks MooksM275 for your explanation.

My SL600 triggers the check oil level every time i drive it, when checking on level ground engine hot and after 5 minutes it then tells me all is well.

I thought it may have been a faulty level sensor and decided to live with it till its next service, during the service the oil pan was removed and cleaned the sensor replaced and correct amount of oil added.

Five minutes after leaving my indie it triggered again the check engine level warning, again after stopping carried out the above test again comes back oil level ok.

I will check over the weekend the dyno mode procedure to see if i can stop this from triggering early.

My question as i am not sure i follow can these changes -3 and +3 be made in dyno mode or does it require connecting to DAS.

Many thanks

 

Sorry your having troubles.

As far as the correction -3 +3, this can only be done using the DAS under Intrsument Cluster>Control Unit Adaptions>Settings---ASSYST


Aas for your issue, I think we need to collect more info here.

What is the exact warning that is being displayed? add oil or an actual warning that oil level at minimum? Can you give the exact wording here cause would help to know what is triggering it.
Was the sensor you installed new?
What is the Dyno Mode oil Level right now on level ground in morning?
Once entering Dyno mode you can leave on the screen for oil and turn engine on-What is the level when your engine at operating temp, on level gorund idle.
Also, run Dyno mode and leave on screen showing the measurement and try and get the warning to show up so you can see what the level shows at that moment.
Do you have a dipstick tool? this is a good way to exactly measure without any sensors or coding involved.


According to what I understand, your sensor is sending the MM reading to the instrument cluster. If the instrument cluster coding is incorrect or if that minimum warning is set wrong, then there can be problems. I hope we can solve your issue.
