Why would anyone expect anything different? Replacing the failed tank with the same tank? What is the expectation other than another failed tank after x months? I am not sure the tank is the issue or the solution since someone else posted information whatever the cause is damaged the charge air coolers. There seems to be a compatibility issue with the coolant and other components such as tank and/or charge air coolers and who knows what else. Is it the blue coolant which caused BMW to change to the green coolant? Maybe others who have had tank failures also have damaged charge air coolers they just don't know about yet.
