Default Need part number help...

Can anyone quickly let me know what the part numbers are for the EXHAUST AVCS Oil Control Valves on a 2017 STI? I had the drivers side replaced at 35,xxx miles now the passenger side is bad and the dealership is telling me its on back order but i think they gave me the wrong part number when I followed up...

So about 2k miles after changing out my intake control valves, I'm getting the P000D code again. So I'm thinking I need to change out the Exaust control valves now too. Anyone know the part numbers for this? Is anyone aware of a filter or screen that could be clogging causing the issue? I heard something about that but don't see any part numbers for this.

Is this to replace the oil control exhaust valve on the driver side? Part # 10917AA070. Sorry it's kind of hard to tell from the pictures.

Thanks. Got it. Going to do both sides and gaskets. What a pain in the ass this has been.

My oil control valve and bracket exhaust cam (driver side) is leaking on my 2013 sti, it looks easy for me to replace. Is it as easy as just unbolting it and putting a new one on? Do I have to drain the oil since its under the engine? The part number is 10917AA070, I'm not sure if the diagram shadowsports posted is for the same part and the same torque spec, Thanks

Got the exhaust valves changed out. The passenger side is a PITA. Had to remove the driver's side exhaust manifold and heat shield to get to it. Busted a bolt, beat up a couple others. New gaskets too. Had to run to Subaru to get parts. Cost $85. Everything installed. Driver's side was a breeze. Hopefully I don't get another cell. Didn't need to change oil. Technician at Subaru told me to oil the valve well before installing it, which I did.

Just an update. About 500 miles on the new Exhaust OC valve install. No Cells. Car runs fine.

I'm starting to thing that just replacing the passenger side Exhaust OC valve was all that was necessary. Maybe it gets a bit overheated from the proximity to the heat shield and exhaust manifold system. May be a good excuse to install an equal length ceremic coated header system sooner than later. Would love to do this with an equal length header mild twin scroll turbo setup and a slightly bigger turbo someday.
