newish E450 wagon owner here. Purchased used with about 60k miles on it. Just getting to 70k now. One owner car, in great shape.
We were driving the car the other day and the CEL popped on. I ran it through my scanner and the P06DA code came up. I’ve done extensive reading on this and it’s clearly related to either the oil pressure solenoid itself, or the wiring loom.
In most of the reading I’ve done, everyone seems to indicate this will not cause a cel. Well, the only code that my Autel MD808 comes back with (even after clearing) is P06DA control circuit open
My question to any techs out there: is it possible that the solenoid is stuck in the LOW pressure circuit? Is there a way to test for this (I realize there aren’t oil pressure sensors on these cars) Has anyone here actually had this happen to them? Has anyone replaced the solenoid themselves?
If this is the case I’m going to have the car towed to my local Indy to have the solenoid replaced (I will likely unplug it to keep the circuit on normal pressure, but if it’s faulty/stuck in low pressure it needs replaced asap before causing damage).
Here is a YouTube link to the sound of my M276 - I get “ticking” noise from the front right of the motor by the fuel filter, and at the rear. Do these seem normal for you fellow M276 turbo owners?

I know this is a old thread, but can you tell me how you got the new E class 213 to show up on your Autel scanner? I believe it only shows 212 model years, is that what you used instead?

I know this is old, but here are a couple of comments if you get DTC P06DA00.
1. You can manually check your oil pressure using a pressure gauge and connecting it to the oil pressure test port located near the oil filter. (Search for how to do that. There is a procedure in WIS.)
2. Since the low pressure mode is at engine speed of less than 3500 rpm, if you need to take the car to a shop for further diagnostics and repair, don't drive above 3500 rpm. That is pretty easy to do. Keep the transmission in E/C mode.
3. Model years 2019 and newer will throw a CEL. Older cars will not, unless there is a more serious problem. In either case, DTC P06DA00 alone is not a cause for panic (or even the very expensive repair).

I recently experienced the same issue with my 2019 W222 S450. Took it to an indy shop initially but the tech could not figure it out. Ended up taking it to the dealership. It turned out to be a $200 oil pressure valve buried under part of the engine that required $5,000 worth of labor to change out. I appealed to MBUSA and got a 50% "discount" on the labor... C'mon MB. How can you design the engine this way?

Sorry to hear that : ( If you posted it here, forum members would had told you that you don't need to replace it if the oil pressure is good. Did you go ahead with the repair or still pending? Hopefully the latter.

I went ahead with the work since the CEL wouldn't go away and the car needed to pass inspection.

You have the M256 engine. The oil pressure regulation is a little whacky, in my opinion. You probably were smart to have the dealer fix it.
I really hate newer cars!
EDIT: Looking at the TIPS document again, it does imply that the P06DA00 is not a serious fault.

How did you appeal? Is there a formal process or something of the like? I actually find it shocking that the dealership was so transparent -- or foolish -- that you were able to figure out it was a $200 part and $5000 of labor, unless it was right on the bill that way.
Did you appeal this after the work was done, or while it was being done? Thanks in advance.

My Boston dealership actually helped with the appeal process. They directed me to call MBUSA to start a case and followed up with MB to get authorization before commencement of the job. I only wish there was a way to code out the CEL fault of this none essential part.

As mentioned prior, if you didn't get this job done and posted on the forums, we would had told you to measure oil pressure and then plug a dummy solenoid outside the engine to disable the CEL. Since you already got it done, I think you should just continue with enjoying the car and not look back.
jumping in late here as I just got this code 200 miles after hitting 100k on my car. What is a TIPS document? How hard is it to change the solenoid itself? I’m pretty handy.

Do not change it, unplug it and then plug a dummy solenoid outside the engine once measuring pressure is good.
