Has anyone had a problem with the water pump on their 2014-2015 R 12 GS or GSA? I have a 2015 GSA that is in the shop for the 6K service. The dealer advised me that my water pump was leaking and that it needed replaced. Upon asking a few questions the dealer advised that I was lucky to have made it to 6K miles because they have replaced several of the water pumps at the 600 mile service. Is there a problem with BMW water cooled boxer cooling systems?
