New member here...I purchased a CPO 2013 BMW 650i Xdrive Grand Coupe. It had 36,000 miles. In the 5 months I've owned it I have had to replace the ignition could twice - going in for the third time next week, have blown the cigarette lighter fuse three times and have had to add two quarts of oil. Seems like I have bigger issues but the dealer says it's just the coils gone bad? Any adviice as to what I need to ask him to check?
