Unplugged W166 2014 ML63 with Performance Package.
Plug was pain in the axx to get to due to coolant pipes being in the way.
No oil present on plug and taped up end of plug with electric tape but could not zip tie anywhere because the plug wires were very short.
Confirmed with scanner as code P06DA00 showed up.
No CEL also confirmed.
Test drove after unplugging and oil temperature is definitely moving up much faster than before.
Cannot yet report shift patterns due to short test drive but will report back soon on what changes.
Have to wonder if at some point the wire harness got torn and at that point was shortened because my car had plenty and on the other vehicle right to the exact same thing it had plenty..

Since that exposed end is part of the wiring harness leading to the ECU, you definitely want to close it up with either a female connector (or male--I'm woke and can't figure it out) OR attached a dummy, decoy solenoid. Lots of discussion above about using a matching connector housing to connect and protect that wire connection. See post #942 and after.

No oil on my plug either, unlike the CPS's I replaced last year.
Also found the wiring harness a stretch to secure on my ML63 but managed to get a cable tie around the coolant hose to keep it out of harm's way. I used a spare camshaft magnet harness to protect each end from the elements.

Nope. Not needed for the C-Class or SL-Class or any other class that doesn't have an oil pressure sensor. I'm just adding the dummy/decoy solenoids to get rid of the P06DA00 DTC. I'm just OCD about DTC.

I'm not convinced it's "needed" even for the rare applications with an oil pressure sensor.

compile a list of engines that feature dual-pressure managed oil pumps ChatGPTAs of my last knowledge update in January 2022, I don't have specific information on every engine with dual-pressure managed oil pumps, as detailed specifications can vary among models and manufacturers. However, I can provide you with a list of some automotive manufacturers that are known for incorporating advanced engine technologies, including dual-pressure managed oil pumps, in some of their models. Keep in mind that newer information may be available since my last update, and you should check the latest sources for the most accurate and up-to-date information. Here are some manufacturers that are known for incorporating advanced engine technologies:
BMW: BMW has been known for incorporating advanced engine technologies in their vehicles.
Audi: Audi is recognized for its innovative engine designs, and some of their models may feature dual-pressure managed oil pumps.
Mercedes-Benz: Mercedes-Benz often incorporates advanced engine technologies in their vehicles, and some models may feature dual-pressure managed oil pumps.
Porsche: Porsche is known for high-performance vehicles and advanced engineering, and certain models may include dual-pressure managed oil pumps.
Volkswagen: Volkswagen, particularly in its higher-end models, may feature advanced engine technologies.
Ford: Ford, in collaboration with other manufacturers, has developed advanced engine technologies. Some of their higher-performance models may incorporate dual-pressure managed oil pumps.
Chevrolet (General Motors): GM is a major player in the automotive industry, and certain Chevrolet models may include advanced engine features.
Volvo: Volvo is known for its commitment to safety and innovation, and some of their vehicles may feature advanced engine technologies.
Remember that the inclusion of dual-pressure managed oil pumps in a particular model can vary depending on the trim level, engine variant, and model year. Always refer to the latest technical specifications or consult the manufacturer for the most accurate information.

Which Mercedes-Benz engines use two-stage oil pumps? ChatGPTAs of my last knowledge update in January 2022, I don't have specific details on individual Mercedes-Benz engines that use two-stage oil pumps. Automotive manufacturers often update their technologies and specifications, and new models may be introduced with different features.
Mercedes-Benz is known for employing advanced engine technologies across its lineup, and the use of two-stage oil pumps might be present in certain models, particularly those designed for higher performance or efficiency. To get the most accurate and up-to-date information, I recommend checking the official Mercedes-Benz website, contacting a Mercedes-Benz dealership, or referring to the technical documentation provided by the manufacturer.
Keep in mind that engine technologies can vary across different models, trim levels, and model years, so it's essential to refer to the specific technical specifications of the vehicle you are interested in for the most precise details.
I bet Bosch ran a custom version of intelligent design CAD to discover random engine oil pressure could save gallons of gasoline worldwide... the low pressure pump was born
Looking at WIS and the oil pressure test procedures and acceptable test results. I was not aware that between .9 and 1.1 bar oil pressure is acceptable at 600 rpm. No wonder the Camshaft Adjusters fail, I'm surprised they last very long at all.
Seems I remember someone presenting a document from the VVT maker requiring more pressure to operate properly.
13 to 16 psi at idle, and 25 to 36 psi at 2500 rpm... When 3500 rpm is 50 to 70 psi, so idle should be at least 35 psi and 50psi at 2500 rpm unplugged, if not better. I'm basing this off of other engines I've tested oil pressure on in the past, so your mileage will vary.
My old 1981 HD Shovelhead runs 15 psi at idle, but it's air cooled with roller bearings for the crank, rods, and camshaft.
