So I recently bought a 11' e90 328xi with 55k on it I came across an engine light after getting my oil changed from the dealer I bought it from (It was free) and my service engine light comes on with codes p0012 p0015 intake/exhaust camshaft position timing over retarded. My car runs perfectly fine until after running it I come to a complete stop and put it in park and let it idle at 600 rpm it decreases to 3-400 rpm and kickes up to about 1-1200k and goes back to normal and cel comes on for a couple days and turns off, it does not do it often at all just at random times. just want to fix it before something goes wrong, what I have read was a vanos or a camshaft sensor or a new oil change? Car has 64k miles also comes with a change oil code even tho I reset it in the computer. I'm new to these cars to any information will help, thank you.

Try swapping the vanos, if not replace. if you know how to work on cars. read on it. lots of info here. good luck!

I got the same codes today... think its the camshaft sensors... did you fix your issue? if yes, how so?

Your timing is off . If this code came right after they did the oil change they did it incorrectly. Vanos system works off oil pressure dirty oil and low oil pressure will throw timing off . N52 takes 7 qts of synthetic oil 5w-30 check your oil filter cap and see if the cage is in there there's two o rings on it that need to be changed every oil change
