You do not need BMW to "analyze" anything for you, you can analyze the problem yourself.
The problem could be due to a weak design or part, or the problem could be user induced in one matter or another. Either due to lack of use or abuse.
Abuse could be trying to open the window when it is iced up (someone is located in the North East!) to even how hard a door is slammed. Maybe not "intentional" misuse, but sometimes you have to stop and look at the much bigger picture.
Kind of like expansion tank failures, many of they are due to either overfilling the expansion tank and there is no room for expansion to a expansion tank cap that dues not vent properly.
And correct, many forum members here and on every forum come to share experiences, compare problems, and understand how to fix specific or common problem. The only real way to solve problems over the Internet is if there is a common problem that many people have personally addressed.
Uncommon problems are very hard to solve over the Internet without being able to get hands on with the vehicle.
Anyway, I hope everyone uses the correct coolant, not worth the risk with mixing, many parts stores both chain and local import stores now stock coolant for German and Asian manufacturers. Even my local Advance Auto stocks BMW brand coolant as well as CHF-11s power steering/hydraulic fluid.
Also I always fill the expansion tank to the low side. As I recall BMW states the coolant fill should be checked at 68F. There is quite a bit of expansion and contraction of the total engine coolant fill over a few degrees so this must be considered as well.
Happy motoring and love your BMW!
