Your dealer is wrong. Please find an indy or diy with a friend's help. Water pumps for our cars are getting cheaper as demand increases... thebmwpartstore.com has the water pump for $342.96, thermostat for $77.15 and $8.50 shipping for a grand total of $428.61 ($46 cheaper than the previously posted deal).
Water pumps are just about the only thing that will strand you with our cars. Once yours is replaced you should be good to go for many more trouble free miles.
