May have to replace mine. Bentley's says in mounted to the front of the engine block. Where exactly is it located (Pic?) and is it accessible for a garage DIY.
Thanks

Oil pressure control valve? Are you referring to the oil filter housing with the attached engine oil thermostat?

[Orion4]

Nope. That is the Oil Pressure Sensor (switch). That, in fact, may be the issue. I unplugged the electrical connector and it was full of oil, so the electrical pins were likely shorting across which probably caused: "1C3002: Engine Oil Pressure sensor, electrical: Short Circuit to earth." Replacing tomorrow evening when the part arrives.

Think I found the control valve mounted on the front of the engine to the passenger's side of the crankshaft pulley.

Looks like you don't have to remove too much to swap that out. But like any other BMW part, it's somewhat of a PITA to get to.

Like all of us BMW DIY'ers, I've gotten use to be a contortionist and have developed an expanded vocabulary of expressive terms that would make my former Navy Sailor Shipmates blush!

[Orion4]

Faults solved!! The culprit was the Oil Pressure Sensor. Wad pretty confident that was the problem when pulling the electrical connector and finding it full of oil!!

Hi, what where the problems your car had? I’m also changing the oil pressure control valve but it seems like it is stuck. Did you just unscrew the bolt and pull it out?

[Orion4]

If your engine is configured the same as mine and uses a similar control valve. Remove the bolt to release the valve. Fault code: "1C3002: Engine Oil Pressure sensor, electrical: Short Circuit to earth." Turned out to be the Oil Pressure Sensor which sits just behind the OFH toward the Driver. Yours may be in a slightly different location adjacent to OFH.

Thanks for the reply. I had to check the oil pressure valve and it was good. Kinda looks like a VANOS solenoid but lower on the engine block. It was hard to pull it out because it was a really tight fit. It’s kinda uncomfortable to get down there, but basically you just have to pull it out evenly from both side ( instead of just pulling by one side like I did). I’ll put this out just in case somebody will need it

I have a 2013 Bmw 335i Also having oil pressure issues, car is on a strong tune from a guy i bought it from, replaced the fuel pump and sparkplugs and started up like nothing. Im getting codes for 1C2002(Oil pump pressure too low) and 1C0102(Oil pressre control,Plausability, Static, Pressure Too Low. Im really hoping it could be the control valve or maybe the sensor on the oil filter housing because oil pump would mean really bad news.

Hey John, any luck with figuring it out? I’m having the same issue and similar codes and wondering what could be the problem.

i’m a bit late, but i have a constant 1c3102 code, and i do remember one time i found a 1c2002 code but it has not come back since i cleared it. i replaced both the pressure sensor and solenoid with no luck.
for my case im starting to suspect the oil pressure sensor wiring or the ambient pressure sensor is bad.

I know this is an old thread, but there don't seem to be a lot of threads on this.

Is there a trick to getting it out of the engine block? I can get mine to twist but I cant get it to pop out. Bolt is out, unit twists, but I can't grab it with anything meaningful to pull it out. How did everyone else do it?

[SharpAndCunning]

Has anyone replaced this with anything other than OEM? Seems like continental makes ones, as does URO and Gates. But I can't seem to find who makes it for BMW.

i'm hoping you got it out already, but I just removed this from an N55 engine that was removed from the vehicle. even with the engine out, it was extremely hard to get out. i was able to use a very thin pry bar to get behind the plastic flange and pry it out.

I tried that from under the car (obviously with the engine installed) and the plastic separated from metal core.

I ended up finding a 1/2-13 Tap and carefully threaded it into the aluminum and once it grabbed it started to spin and loosened it. I then used a extra long pair of vice grips (Harbor Freight) and cranked them onto the tap and pried against vice grips and it popped out.

What a PITA it was. Sucks I ruined the sensor. To be honest, for the 1qt or 1/2Qt it would leak between oil changes, I should have just let it continue to leak, haha.
