have 135i conv with 2000klms. fuel economy very poor around town - 18l/100km or 15mpg when not driven hard......don't really care about economy but concerned that there may be an issue/ problem. any thoughts / advice

thank you. wasn't worried about the economy itself just wanted to be sure there was no problem. can now seriously enjoy this exceptional vehicle!!

I get about 16 mpg street/ 21 mpg highway when not driven hard on my 2010 135i Conv. w/ Sport Pkg. and Auto.

Anyone else getting better mileage and how?
