I know ABS service is recommended and the dealership recommended it to me last time I was in there, but it was some ungodly sum of money (can't recall how much but I think it was in the $300 range). I was wondering if anyone has had this done and what a reasonable price might be. What do they do, just flush the system? The X is the first vehicle I have ever owned with ABS so I'm not familiar with what service is invlolved.
