Did a fault scan because it (n62 - 4.8is - 08/2006) rattled and rumbled like hell occasionally (sometimes shortly after cold start, sometimes after several days without issues).
First thought was: man I'm loosing a tire or something like that - felt like an unbalanced wheel but happens at 30km/h until > 200km/h

Scan result was: 2A83 (vanos inlet), 2E68 (knock sensor 1), 2E69 (knock sensor 2)
Sounds like vanos solenoid(s), right?
