I'm not sure about this but I believe the vanos unit and the camshafts are more or less one piece. If this is the case, it may be in your best interest to replace the whole thing just because if you loose the ability to control your valve timing, you can really mess the engine up.
Also, if you do end up deciding on replacing it, perhaps you should check in with ACSchnitzer and see what they offer in terms of vanos camshafts for the euro engine. If the cost is not that much more, it will be a good excuse and the cleanest way to get more power out of your car.
Finally, if you are adamant about fixing the piece yourself, try to get a used unit and put that in your engine and then open up your noisy unit and blueprint it yourself. Its hard to get those though, especially in the uk. Not many Ms running around in RHD trim.
