Subaru Ascent OCV

Hi all My wife has a 2020 Subaru Ascent. She loves the car but got a whacky check engine light occurrence. Reviewing the cOde P0014 I read it could be dirty oil or sludge build up ( she got it changed recently with no notes about build up)

A ECM update that is the 2nd most popular issue and other possibilities

I called our Subaru dealership and they would want to dig in and check the Oil Control Valve (OCV). And everything else before applying that update. He quoted me 1700 if it is the OCV but googling this stuff and talking to mechanic friends that seems really high. I guess they would replace and then do a full engine flush. If it isn’t clogged then they would try the update. He also told me most mechanics wouldn’t know what to look for. So go dealership. Uh huh…..

I’m not saying AI is right or google but does that seem high? Has anyone experienced this error and it be an update to tb 09-22-26 ? Last time we went there a few years ago a oil change was double thab her usual place so I know their prices can be inflated

I also just dropped 5k in my injured/ now deceased pup and my car in the past minth and can’t add 1700 lol.

Thanks for any insight !
