MPG Dropped Considerably
i’ve a m235i xdrive DCT with 90k miles that lately is displaying a lot worse mpg (earlier than 32/23, now 20/15). There are not any fault codes current based mostly on each the seller and bimmerlink diagnostics. ive ran a can of 44k, modified the spark plugs and had the seller carry out gas injector service no matter that’s (i in all probability wasted my cash). I feel the more serious mpg is because of dangerous o2 sensors however wouldnt that throw a code or journey a engine gentle? It’s performing high quality, aside from the decrease mpg. Respect any suggestions. Thanks.
