Hi ,I am looking for oil pressure switch on m272 engine in 2011 e350 .but couldn’t find it. And online it only shows oil level sensor.
Oil pressure switch part no 0051530628.
If this is accurate, looks like it might be threaded into the oil filter housing. There's debate whether these engines have oil pressure sensors, as there's no idiot light, nor warning message per the OM.

I tried looking everywhere but no luck.
I use liqui moly 5w40 with mann filter always.
How much is the oil capacity for2011 e350.
Here is story. I always use 5w40 liqui moly . But just for once I used Castrol 0w40 for winter . And after than car feels sluggish at 7-8000 miles. I changed oil again with liqui moly 5 w40 but it’s sluggish. Rpms fluctuating while driving under 2000 rpms and car just doesn’t feel good. At idle it’s fine then I ran a scan I got code p0521 on OBD2 for oil pressure sensor out of range. now I corrected the oil level but still same. I had c300 2008 with same engine in 3.0 l that ran buttery smooth even at 180000 miles.

Generic code P0521 may actually be referring to: "MB code 0521" (P2004) = Tumble flap shafts stick in the actuated position. This would explain your sluggish performance. If in fact its the tumble flaps sticking, start looking into having the intake manifold replaced. This is an early sign the mechanism is getting "gummed" up and difficult to move. Usually a lever on the outside of the manifold is the first to break due due to the force required to move and it being made of plastic.
You should be able to slip your finger on the right most lever/linkage and push it towards the passenger side and "feel" if the mechanism is "stiff". Should move freely, with only a slight bit of resistance.
N3/10 - Motor electronics 'ME97' for combustion engine 'M272' (ME)
Code 0521:
I cannot find a single oil pressure related fault in the N3/10 module (engine management, ECU) NOR data stream related to oil pressure. The ONLY fault code and data stream are for the oil level sensor. Now if this oil pressure sensor is tied to a different module, which would be odd, I haven't looked that far.
This to me just further solidifies, at least, the M272 in the W212 chassis and I'll take a leap of faith, the M273 DO NOT have oil pressure sensors.
I have the error code P0521 on generic OBD2 Bluetooth Adapter used with my Android phone.
I have the part #0051530628 and I am going to replace in next couple of days, Oil change done recently(Liqui Moly Green Oil), Intake Manifold Tumbler Flaps feel fine and functional after moving them by hand, No sticking and moving freely, no cracked plastic piece. I just replaced the plastic air bellows a.k.a. Intake Tubes.Cleaned the Air Filters, oiled them and let them.dry properly, cleaned the Mass Airflow Sensor with QD Parts Cleaner and compressed air. Made sure the Intake Air Box was seated correctly up against the MAF Sensor. I also replaced the Belt Tensioner, both pulleys and the belt and the car is driving like a brand new Mercedes-Benz. No errors on dash, just noticed the error while doing presentation services and ran a scan. With these machines it is less expensive to continuously monitor and service it, than to wait for things to fail completely and wipe out other systems in the process. In my opinion.I will update after replacing the Oil Pressure Sensor part #0051530628.
An old thread but familiar question. M273s do not have an oil pressure sensor. If you want one, you'll have to drill a hole and install one in the oil filter housing and then connect a guage to your dash.

Can't speak to M273, but if it is in the same family of the M276/M278, there is a 12mm plug on the oil filter housing--no need to drill holes. The plug is the same as the one used for the transmission pan. It's used by the shop to diagnose or measure oil pressure using an external, mechanical oil pressure gauge.

I'd say this video shows the already drilled inlet you're referring to, even though its an older model V6. I had seen a video showing someone drilling one, but your post reminded me of the existing outlet - thanks
