BMW 535i xdrive N55 Low Oil Pressure (2013)

[NardoF10]

Hello everyone, this my first time with any issues like this and the dealership isn’t much help. so I bought my car with 97k miles and it needed a transfer case and contol unit. Fixed those and by the time i hit 100k i get a drive train malfunction. Shortly after (twice total) i saw a message on dash low oil pressure, do not continue journey. Shut off engine and call dealership. I restart the car, problem goes away except for drive train malfunction. It all started after I did oil change so I figured maybe wrong oil. I did 5w 30 first then a few days later 0w 40. The problem was still there so I changed both the oil pressure sensor and hydraulic valve. The problem still continued. I have the INPA Ista+ software to diagnose my car and the codes shown is 1C2002 & 1C0102, oil pump pressure too low and engine oil pressure control, plausibility, & static: pressure too low. Further diagnosis with the program says the problem may be caused oil pump sticking. Last thing I noticed was my pulley a little shaky and i hear noise coming from it. The engine has no knocking noises or anything, the car still runs and drive now normally but i do not drive it at all. How can i go anout fixing this issue? Is the pulley shaking correlates to the oil pump issue? Do i need to replace oil pump? Also how much does it cost and reference to any shops? Dealership told me 5k for just oil pump replacement 7k if there are any damages to engine. Any helpful advice is welcomed because I already spent alot getting new transfer case.

What is the oil pressure at idle? You can check with either INPA or INSTA. I believe spec is about 2.5 bar
