Then hit the brakes hard to stop as rapidly as possible whilst trying to avoid having the ABS kick in. Do NOT allow the car to stop but to slow down to about 5-10 mph. Get back up to speed and about 2/3 minutes later go to 60 mph and repeat the above. Again let the brakes cool slightly for 2/3 minutes and get up to 70 mph. Repeat the above, and again from 80 mph down to 5-10 mph and lastly if you can get to 90 mph and do the above. When you've finished with the above, drive for quite a few miles to allow the rotors and pads to cool. Do not come to a full stop if at all possible whilst doing the above procedure. If you are forced to, keep your foot off the brake pedal when stopped.
The above should remove any irregular deposits on the rotors and place a uniform layer of pad material on the rotors. If it doesn't work, then you can try the above with a more aggressive 'track' oriented pad which should nearly always do the trick. Having to scrub the rotors would be the last thing to try and don't let anyone 'turn' the rotors for you; the rotors aren't warped, (or at least the odds of that being true is very low).

Much appreciated Bish, I followed BMWs bedding in process for the brakes when I took delivery which differs from this so I will give this a try and report back. Getting up to 90 and then back down to 10 in this car is not a problem here trust me!!
