Sounds like the Dealer needs to do some more troubleshooting. If they already replaced the master cylinder, and bled the system, I would look at the ABS unit. Have you hit the brakes really hard to activate it? Most ABS systems have an accumulator that is sealed from the factory, but it is possible that it might need bleeding. I would imagine that the DSC is also tied in with the ABS system. Have you tried turning off the DSC, and noticed if there is any difference? Just keep taking it back until they find the problem. Please post what the final culprit is.
