This problem is occurring on all e46 330 m54 engines with the zhp(performance package) there have been numerous complaints to BMW na about this issue. At 2000 - 3000 rpms the engine rattles like a coffee can full of marbles. I took my vehicle to BMW but they stated that this is perfectly normal. BMW is not willing to do anything about this issue. The issue is the dual vanos unit they put into the m54 engine is using belrin bushings and they are failing. There is a company called dr. Vanos that fixes this issue by rebuilding the oem vanos with upgraded bushings. This unit cost $500, which I am not willing to spend as I have a 100,000 mile warranty from BMW.

In 2005 when driving my car, the car began pulling unevenly, jerking gently on acceleration up a highway bridge and the problem persisted to the dealer for service. The ignition coils were replaced under warranty.

While driving, the vehicle lost power. Theconsumer managed to pull over and had the vehicle towed to the dealer, but the problem was not resolved.
