If you do have to go in and drop the sub frame and change out the sump or whatever is inside the engine, what would something like that cost? Mercedes here is quoting almost $5000 to do the work on a 2019 C300. Just wondering if we should take the car elsewhere for repair.
Have this issue now with our 2020 GLC300. REALLY appreciate this video! Have also read that this part - which is designed to very slightly improve gas mileage by reducing parasitic drag at idle - can actually cause more engine wear in the longterm. Accordingly, many now recommend ignoring this CEL code. Unfortunately for me, my state (Illinois) won't perform my emmissions test if the CEL is on for any reason. With this in mind, I'm thinking maybe I could unplug the wire (as shown in the video) and connect it to a homemade fitting with a resistor of the appropriate reading to fool the system into thinking it was conncted to the oil pressure solinoid. Anybody have thoughts on this and how best to do it?
@@kennedysgarage3281 I found a Mercedes owners group that has dealt with this issue successfully by disconnecting the cable that connects to the connector at the engine block (i.e. to the cable and solenoid inside the oil pan), buying a replacement solenoid and then connecting it to the disconnected cable. They zip tie it safely away from any moving parts. Basically, this set-up fools the system into thinking that everything is fine without having to remove the oil pan to replace what is likely the defective cable and/or solenoid inside the oil pan. The side benefit is that normal oil pressure is restored at all times (like used to be the case before car companies started using every trick in the book to increase fuel mileage). Mercedes has indicated ignoring the fault code - which means oil pressure is never suppressed) is not an issue. Quite a few owners on that site have used this fix successfully without any issues. I'm going to give it a try.
The oil valve is a normally open solenoid, so it is a fail safe design. When it fail or not energized or OFF, the oil pump is then like a normal oil pump with higher oil pressure at lower RPM. This oil valve is called Y130 on M276 3.0 Turbo engine and as with most MB component naming/ID scheme, most engines will also call it Y130. Fuel savings from less parasitic load of higher oil pressure in the engine when RPM is at lower region, is MB design target. PWM signal at 200HZ is how it operate. 10% duty cycle if OFF. Mercedes call this a 2 stage oil pump. In the 6 cylinder M276 family, 3,500RPM is the trigger to turn OFF this oil valve to allow oil pump to give maximum oil pressure at about 55PSI. ======= A test on M276 3.0 Turbo of E400 W212 oil valve, only at 3,500RPM the oil valve get turned OFF. See here : ua-cam.com/video/qFikhwMenFk/v-deo.html ======= A test to show actual oil pressure control in PSI this oil valve is doing.

Hello! Thanks for sharing this video. I have a C300 2019/61K kms and it was diagnosed with P06DA00 by the dealership when CEL came on. The dealership also gave an estimate of a few thousand dollars to fix the issue . The CEL illuminates intermittently and the vehicle appears to drive fine. When I looked up online on forums and other pages, they say that this fault code can be ignored. In your opinion, do you think I should get it repaired or ignore the CEL until it stays on for a few days without going off? I appreciate your advice on this subject. Thanks.
In my opinion and this is just my opinion, I think with the high value of the car personally I would like the engine ECU to be able to control the oil pressure as designed. They say that when this oil pressure solenoid or loom fail that the oil pressure goes high & shouldn’t effect it too much. But if everything oil pressure related is under more strain at all points in time it cannot be good for it 🤷🏼♂️🤷🏼♂️ You should be able to get repaired for around €1200 to €1500
I too used to collect various parts to use as tests components with diagnostic. Then I brought a resistance decade box that allowed me to dial a resistance value. Top tip don't buy the cheap Chinese one like I did. Ended up buying another one which was far better quality and fit for purpose.
I have 2 decade box’s there but never even thought of it for this test process. If I tell the truth I really only use it for temperature sensor tests. But a really good tip Chris 😉🙏🙏
Mechanic told me I just need a loyal change had the same code 2019 a220 period it came on about 3000 mi overdue for an oil change, I put oil in code went away. Going to take it now to have an oil change
GREAT TEST DEMO....i ACTUALLY HAD TO REPLACED ON MY '15 c300, HAD TO REPLACED AND ANOTHER '16 c300. MBZ SHOULD HAD RECALLED ALL M2784 ENGINES... TOTALY FAILURE. NO MPORE MBZ, AFTER OWNING MANY MBZ IN MY ENTIRE LIFE.....
I dont have a check engine light on but i did a diagnose with this app called fixd and it’s giving me a code P06DA unknown engine error and its saying its major…should I be concerned is it safe to drive?
This car was driven for 8 weeks after I diagnosed it first, which means that there might not be any immediate urgency. But any thing oil related must be taken relatively seriously. I would advise getting it resolved as soon as you can 👍
Nice diagnosis 👍, First i have seen anything like this oil pressure control is there any real need for it ?, I wonder why this is fitted 🧐 maybe something to do with the vvt control ? Thanks for sharing.
Emission’s I would say, reduced drag from the oil pump when high oil pressure is not need. I could very well be wrong & look forward to other peoples thoughts 🤔🤔
We didn’t see the actual repair. Do I need to loosen the engine mounts and drop the steering rack to pull the pan on this? Also do I need to pull anything less getting to this like the dipstick or oil pickup?
@@kennedysgarage3281 yea this is a bummer. Good thing I have an engine hoist and other tools. What a pain just to replace a valve and harness. I need to get on it though because I’ve been driving my F250 diesel and it’s 150 a tank here.

@@kennedysgarage3281 You are most welcome. I enjoy sharing what I too have learnt👌
@@suryaprihadi2258 😉😉
Awesome explanation. Are there any risks to the engine if the wiring is left disconnected? Does P06DA trigger a MIL/CEL?
Also, 3500 rpm seems awfully high for the solenoid to deactivate and permit normal pressure. Most of my driving (M276 3.0 turbo) is under 3500 rpm.

What engine is that? I have the 1.6. I think the wiring comes out of the plug and the plug gets loose.
i have same problem, will this badly affect the engine?
My one was 2.1d and the wiring loom submerged in oil failed on my one & not the block connector 🤔🤔👍
@@sparts6825 no. It is actually more beneficial to the engine
@@AnthGott is this true i am scared to drive my car with this fault present ?
