Last year the Vanos failed on my 2000 E39. Symptoms were rough idle, "pushrod V8" exhaust sounds, smoky exhaust. My code reader told me it was an O2 sensor. Then the car developed an alarming oil leak out of the left front spoiler. Turned out the Vanos pump was leaking. It allowed engine oil to be sucked throughout the intake system, necessitating the dealer to remove and clean it, at major expense. Did a nice job, but it was costly.
I've seen earlier posts on this board re. when the dealer will or won't replace Vanos.
