Exclamation Service Engine Soon

bare with me,

I first got a Service Engine Soon light and the codes were P0014 and P0015,
I had both cam position sensors replaced , then I got P054b code. After that I had both Vanos Solenoids, the Tensioner, along with all 6 spark plugs replaced.
Also replaced the valve cover gasket because it was letting oil leak out and causing engine smoke.

with all of this being done I lost a lot of oil in the process and did add a quart while this was going on.

I haven't gotten to clear the engine light yet but i do hear a weird sound in the engine and also at idle, it almost sounds like a diesel or a low knocking sound. During acceleration its less noticeable and can't really hear it.

prior to all this I took the car to BMW and all they said was they ran a test and I needed the Vanos Solenoids replaced.

So basically I have done everything BMW has said to do along with other repairs and I still continue to hear an uneasy knocking diesel type sound. I have noticed it feels like I have less power than I did before all of these issues but I could also just be paranoid.

Basically my question here is what could this sound possibly be ? and would my SES light clear on it't own?

I do have a video of the engine sound that I am going to try and post.

Since you replaced the timing chain tensioner already, it could be your actual VANOS unit that might have to be rebuilt. There is a kit out there for that. Not sure, just a guess.

when i took it to BMW asking them to replace my VANOS system they said that wasn't the problem. I'm thinking it could possible be the Eccentric Shaft Sensor?
