Keep in mind that the same condition is caused by a broken wire inside the oil pan. Putting a car into limp mode because of that is unjustified. It causes no harm to the engine. Limp mode is intended to protect the engine from damage with normal use.

If Bosch/Daimler are forced into reworking dry oiling, they're may further prevent well intentioned ppl from making things run well. Don't get confused: I was the first to pull the plug, not the one who engineered this chaos. At first I didn't know what to expect from normal pressure. I was quite surprised when smart pair of ECU-TCU started to tune up automatically. I realized the normal pressure helped fill up a giant performance gap.
The current theme is to produce controls that simulate old engines... Once you understand the playcards, you can peel off the onion to a level you are more comfortable with.
MB electricals are a contrasted mix of the best technologies. Treat your car to a clean regulated voltage. It's the basis for all 46 computers to tic.
Performance & longevity are trade offs. When you reverse course, you may encounter both combined such as in this amazing thread.

Reason: VOLTAGE is to computers what OILING is to engines...
Just unplugged my 2015 s63 coupe a few days ago at 57k miles. Wish I knew we had an oil pressure sensor before pulling but I read that after I pulled it. But I will still try to read pressures post-pull shortly. Also going to unplug my wifes GLS550 with 109k miles shortly. Thank you all and Merry Christmas!

Just to clarify..there is no oil pressure sensor on your car. Or for that matter most other MB engines made from 2010 onwards...You will need to find the oil gallery plug and plumb an oil sensor in. route the wire to an electrical oil pressure gauge in the cabin. Or get a mechanical oil pressure gauge and plumb that in routing the oil line to the cabin. Avoid crushing the oil line. !!

I read that the s63 has one, I guess I'll confirm this week!
It seems to be used on turbo engines ( fitment/applications section), and you can see the location in the diagrams.
I assume those engines should be able to read it via Xentry -> able to code it to the cluster?
Here is a picture of the part from EPC, #250. It is supposed to fit a 2015 SL400, which I have. I will have to take a look tomorrow. Now, I just need to find it in XENTRY.

Checked this morning and could not find the oil pressure sensor on my car. I did find the torx-head bolt where it might screw in and where a manual pressure gauge could be attached, but not the sensor in the diagram.
If that is the case, then why not just find an oil pressure sensor with the same thread and run either an electric or mechanical gauge?
Too bad the m157 filter housing doesn't permit fitting a pressure sensor/temp sensor housing between the block and the filter (like I had in my Subaru).

I am curious about the oil pressure now that I disconnected the solenoid. So, I ordered this test kit on Amazon. I was considering an electrical oil pressure gauge, but really didn't want to have to find a place to mount it inside the car. I may change my mind later, but for now I figure I can hook this up temporarily and run the gauge out by the wipers while I take a drive. For less than $30, I figure it was worth knowing for sure what is going on with my cars. I do NOT plan on a "before and after" test, hooking the solenoid back up.

Ha! I was composing the post that just addressed this.

I think that is what the 2nd diagram (M157) is showing. The oil port is located on the filter bracket. It looks like the torx-head bolt (#140) fits the same hole on other engines. I don't have an M157 to look at.

On my 2014 E63s i have this torx bolt. Someone posted the WIS earlier in this thread for checking oil pressure and it says to use this hookup point. S63 M157 should have a sensor in this location. Wonder if anyone with and S63 and Xentry can try and get a reading.
Going to try and hookup a sensor here myself and figure out how to mount a stealth gauge in the cabin.

XENTRY has a simulation mode that I tried to use to see if there is an oil pressure monitor, but had problems with activating the ECM. I may need to enter an actual VIN to find the reading. I tried both the N3/10 module (ECU ME) and the A1 module (Instrument Cluster IC), and could not find it. There are a lot of level and temperature sensors when looking at the Actual Values tab under XENTRY Diagnosis, but no Oil Pressure. Further, when looking on my car (SL400 with M276.825 engine), I could not find any wire that would connect to the Oil Pressure Sender even if I did install the factory sensor.

I tried to configure an S63 in XENTRY and check Actual Values. This is what I got. And when trying to set up a custom Individual actual value group, oil pressure was not listed.

Nice try with digging into this. I know nothing about Xentry but see myself becoming familiar some time soon. Guess I need to gear up.
I’m thinking the easiest way of looking at oil pressure will be via a modified cap. Because the pressure variance has been removed, it should be a matter of looking at the gauge under the hood at various temperature and rpm levels. Pressure should follow rpm - drive some to get it nice and warm, and then have a helper on hand to rev the engine to specific rpm levels while you record the data at different rpm points. This can all be done in your driveway, on the side of the road, etc. Repeat the test post-different driving conditions. Using this method, you’ll be able to map the oil pump’s capabilities.
If displayed oil temperature is close to actual, there really won’t be much of a need to monitor pressure constantly either.
Does anyone know the thread pitch for a external sensor? I am currently running a banks data monster and I can attach a external oil pressure sensor to the gauge to read out info

The part number for the screw/plug is N000908012009, but the EPC does not give thread and pitch size. The oil pressure test kit above has multiple adapters. I we can't find that info anywhere, when I get the kit, I will do an oil change (already within 300 miles anyway) and measure then.

Interesting that a search on that part number returns the drain plug for the tranny oil pan. So, that is one way to figure it out. I wonder if I have a spare drain plug.
EDIT: Looks like it's an M12x1.5

A forum member with an S63 (w222 forum) saying he did the disconnect and received a CEL afterward. I’ve got 250 miles on mine post-disconnect and no CEL for the oil control circuit. I commented asking if maybe something else triggered the CEL… haven’t looked for a response yet.

There was a commenter on Kenney's video of the mod saying he was a MB tech. He stated that on a lot of cars this code is now updated to throw a CEL. So he may have a newer car and has had MB update his firmware knowingly or unknowingly, because if they're anything like BMW/BMW Motorrad, they will update your firmware anytime you take it into the dealership for service without notifying you.
That, or indeed he does have an issue or maybe his solenoid was indeed stuck in the position we don't want it in and it somehow caused some other incident. No idea unless he gets a code reader or XENTRY on it.

Well, that would suck! That's good to know. I will be sure to tell my dealership NOT to update any firmware or code without my express approval. They have been good in the past not to.
I know when you join the @BenzNinja club that one of the things Peter will do is to make a copy of your existing firmware and settings. I haven't asked him to do that yet, but I will just to have a copy. I also have a tune where I made a factory copy of the factory file and sent it to the tuner ( @VividRacing ). They make their adjustments and send the tuned file back. So, I can always restore the factory or tuned files if necessary (I hope).
Hello from Hungary and Happy Holidays for Everyone!
I got a 14' E63 S and I disconnected the plug today. After it, we went for a 100-120 km drive with family and everything is good. My brother have a 17' S560 with the M176 engine and I want to ask that is that engine have the same "plug"/solenoid?
Thanks for the answer!
Tom

I would be curious to see the code. Could be a coincidence, I believe happened to someone else in this thread. Turned out to be an unrelated code.
