Vanos does have a tendency to sound like marbles rattling around in a coffee can.

is this a good thing or bad thing

This is obviously not good. If you can get the stuff get some BG Engine Quick clean. Add the can to the engine when the engine is at about 1/4 temp, then drive the car for 20-30 min. The more stop and go driving you do the better, this will move the VANOS through its range of movement a lot more than just staying at one steady speed on the freeway. After you are done driving the 20-30 min change the oil and refill with whatever 10-30 you like. We have fixed a few cars this way at the BMW shop I work at and saved our coustomers a lot of money since they didn't have to buy a complete VANOS unit.

I'm not sure if local auto parts stores have it or not but almost every repair shop I have worked in had it in stock so just call arround and see if they have a can. If you are in the Sacramento area you can come up to our shop, we have it on the shelf.

Engine Restore is nothing like the BG Quick Clean. Call arround to the local repair shops that is probably going to be your best bet.

somebody told me i might also have to cahnge my water pump

It could be everything. There all pulleys, it's quite normal to replace them like every 15.000miles

I have the same issue. It could be a timing chain tensioner, or just a rattly VANOS. If you have 60k or more try getting a new tensioner installed. They're not that expensive.
