E63s consumption!! Confusion
the moment i start up my car the avg fuel economy shows up as 30l/100km. Unless i drive 15 km + before it drops to 15-25
even after road trips it went all the way down to 12l/100 km . But after leaving it overnight in the morning when i started up the car shows 30l-100km. Any recommendations? Or is it something i must worry about?
