After reading a thread on this yesterday and today I am confused. I have a W211 on a 52 plate which has now done 123k. Assuming the SBC pump goes will MB cover the cost? And if it goes will my brakes fail with no warning? If so, I find it hard to believe that such a system was ever allowed on a car. Appreciate your input guys as I am now driving in a rather paranoid manner constantly checking for an impending warning light... Not good.
