Does anyone know what this sensor / connection is? We are in the middle of replacing the wiring harness and found this connection to be significantly oil fouled. We don't know what it is nor do we have a clear idea of how to replace it. As you can see in the second photo, it is on the front of the engine, below the water pump, and to the side of the harmonic balancer. Also, any guidance on how to replace this would be most helpful. We have no choice on replacing it as we broke the plastic ears off the connector and now it is essentially flush with the face of the engine block. Regards

Huh Isn't that the oil pump solenoid??? Am I seeing things? The dreaded oil pump solenoid that we all wanted to unplug all this time?
+1 for the oil pump solenoid. You can replace this connector, but you'll probably have to replace the sump. You can safely leave this disconnected. This will create an engine code in the ECU, visible through a diagnostics tool, but it will not trigger any warning on the dash.

Definitely the oil pump solenoid connector. You can confirm this by scanning the ECU. DTC P06DA00 should be showing as both Current and Stored. As mentioned, best to leave it unplugged. Read all about it here: https://mbworld.org/forums/w212-amg/...solenoids.html
Great picture of its location in the second photo!

Thanks for chiming in forum member JettaRed and confirming : )
Agree with the picture being nice and clear : )
I want to add that removing this connector also remove one of the paths of which oil can get in the harness, reaching the ECU, if I recalled, mentioned by a forum member in that thread as well : )
Like we all said, you only get benefits unplugging this, I can come up with a list of bad things having this plugged in and struggle to count the amount of benefits this brings because there are just too many.
I will monitor this area after unplugging though, hoping there is no internal leak from a bad seal or something as in your case, you mentioned there is a lot of oil coming from it but otherwise it is all green light for you : )
Yes yes yes... that is the oil pressure solenoid female side connector near vibration damper pulley.
That one has extra wire and connector to the actual solenoid and sold as a kit.

I would spray that area with degreaser or brake cleaner and "plug" it with a matching connector. I got mine for AliExpress and just trimmed the wires. Just search on the part number.
Thank you all for the information! The connector is completely broken off (not pictured). My thought is to drop the oil pan and install a new connector ($10 part) and then experiment with running it unplugged later. Thank you!

I think you'll find that task to be very involved and time-consuming. If paying someone to do it, expensive. There are some YouTube videos if you search. As long as it's not leaking oil, I'd leave it alone. Just clean up the area and watch to see if it leaks.
Skim this thread and you will see even Mercedes says to ignore the problem.

4-matic to drop oil pan is A NIGHTMARE.
You must drop front sub-frame and hang engine using support bar. No joke.....
I suggest clean the oil traces, if that female bullkhead connector is not leaking oil out, it is then OK.
E350 M276 wont get CEL when the oil solenoid is connector is disconnected and engine response will be better as no more lowered oil pressure on purpose by engine computer.
See Jetta's link on the MOD
Watch this and start at 33:00 minutes. M276 3.0 Turbo and M276 3.5NA is the same for the oil solenoid connector location and arrangement.
Aside from removing the oil pan, because the oil solenoid is IN there and the other connector is there too......
Timing cover must be removed too...dang !!!! That bulkhead female connector is housed at the timing cover.

OP, I agree with everyone else, I actually went through a lot of pain trying to get it unplugged and tried multiple things before I finally succeeded, on my car, it was a very tight spot with the aftercooler in the way. Going from the top you can't even see the connector and I wasn't able to reach it. I even broke off the grey locking pin. From the bottom, the subframe and a bunch of coolant hoses was in the way for me, I spent weeks trying to unplug it and I had to remove many panels to get to it, thankfully forum members kept encouraging me to not give up.
The fact you have it already unplugged you should leave it, it will only likely to do you good.
Don't really want to scare you but I want to state a major disadvantage of having this oil pump solenoid functioning, there is a chance of it jamming and when that happens, it will keep the engine oil pressure at low oil pressure mode at all time effectively destroying the engine hence why unplugging it is still a better idea.
The thread that forum member JettaRed linked is the longest thread on mbworld, for good reasons. The very least I think you should do is read page 1 where OP of that thread posted a FAQ.
Leaving it disconnected seems to be best and I will do that but I have a lingering concern with the broken connector and oil leaking. We broke the connector fairly easily so I question its integrity. I’d feel better replacing it, not the solenoid, if not too painful. To replace the connector, it would seem all that is necessary is to remove the timing cover. Can the connector then be attached to the solenoid with the timing cover off? My guess is it can’t but seeking confirmation before abandoning the idea of replacing the connector.
