I have a 2007 328i with an n52 at 135k miles and 6mt. For the past month I noticed the rpm would fluctuate when im just casually driving, feels like im giving it gas but im not. It also randomly stalls when im coming to a stop. I scanned it and it had vanos inlet code, so I replaced the solenoids (with genuine solenoids) but it still has the same symptoms. I've driven about 200 miles since replacing the solenoids and no code has come back. I also did a smoke test and could not see any smoke coming from anywhere. I noticed that when it stalls, sometimes when I start it up again there's a ticking noise.

I'm stuck wondering what I should do next since there's no codes and no obvious vacuum leak.

Any ideas would be very much appreciated!
