gey guys quick question, I am new to the BMW family as of a couple weeks ago. I just noticed that my MPG meter on the dash seems like it has been low lately. Sometimes when I am coast at 10mph it's not even half full, and I don't have my foot on the gas. Even sometimes when I am completely stopped it will be a little bit under full on that meter. I am just wandering if this is normal, because I didn't really pay attention to it at first, it it seems like it should be full especially when I am just coasting in a parking lot. Thanks!
