2A99 weekend project

[Isaiah24]

2010 528i 157k

after starting the car for about 2 to 5mins on idle, car start to run rough with whistling sound in the engine. Scanned code 2A99 showed up. Took the valve cover off. Found oil gunk residue on the valve cover component that I removed. Hoping that I can upload pic.
After changing the valve cover, solenoid both of them and camshaft position sensor both and the eccentric shaft sensor (since my cousin car are at 157k since I already on that area, thinking might be a good time to change it anyway). Put together back start the engine. The difference between is like driving the car from the showroom
Scanned no code. Happy cousin

Update
the code with 2A99 are 2A98, 2AA4

this is what he gets when he changed the oil between 12k to 18k intervals
BMW should update the change interval by 7500 or less.
