I have a 2008 GL 320 CDI.....we have owned C Class Mercedes passenger vehicles but never a GL Class.....I have noticed that each time we exit the vehicle and close either the front drivers door or the front passenger side door, it sounds like a burst of air is released from under the hood...is this normal and if so, why does it do that? Thanks in advance for your help!!

You may want to post your question in the correct forum. You posted in the X166 section and you have an X164. Yes, it is normal.
