I have a 2011 X3 35i M-sport. When the car began to run, I heard some strange noise like the flow of water in the pipe, both turn on and off the air condition. When the car was stopped, the noise gone. I pick up the car at Aug 2011. This situation has appeared from last month. (The whole last year was no noise.) I talked to the dealer. They said the noise form the air condition pipe in the front dashboard. A lot of people reflect this problem. However, why the noise just show up when the car was running? (both turn on and off the air condition) Are there anyone have the same problem? Thank you.
