Dear S-List, I discovered this past weekend that my car's (95.5 S6) hydraulic pump is leaking, but NOT from the X plug. It looks like it's weeping from between the two halves of the pump. My car has 112,000 miles on it -- should I buy the pump seal rebuild kit or go for a new ($$$$) or rebuilt ($350) pump? Do these pumps ever wear out? Thanks, Russ
