We see alot of 2011 models in here and looks like those models had a very short run oil pressure valve installed.

I’ve seen this theory several times on non-English forums. Those guys never provided any proof, just a generic recommendation to update the valve if you had the first version; or at least to clean it (not sure if that helps). I also heard that 11417584989 is replaceable with the later variation. The wiring harness has to be replaced as well (sorry don’t have the PN).
