Hi guys! My 2005 E90 engine is very noisy! When my ride is park stationary I can hear the engine noise very loud when I'm standing beside my car. When my ride is on the move I also can hear the engine roaring loud.. Anyone know what is the issue? And there is exclamation mark logo beside my daily clocked mileage. What does that logo mean? I got gotten my ride! Very now to this E90, hope gurus here can enlighten me! TIA !
