I have 47K on my 00' CSVT and haven't had any problems so far [knocking on wood right now
] I did cbange the coolant at 30K though, even though it says to do the first change at 50K, why wait
I remember reading about the w/p on the M3's having the same problem and one thing thats said to help those cars is to keep the coolant fresh because it removes any acid build up in the coolant, somethig to think about
Also I added a bottle of waterwetter at 6K and again at 30K after I had the system flushed. I believe in that stuff completely as my CSVT runs cooler than any other I've driven or checked out!
