I think it done to emissions and the EGR,
I had a 2014 2.0d LCI SE xdrive auto, and it always averaged 44mpg, and 50mpg on a long 400 mile run, then early 2017, a recall for a “product enhancement”, they replaced the EGR, the mpg dropped after that.
I now have from new, 2017 2.0d LCI M Sport Auto, and the MPG is always around 37mpg.
My conclusion is to do with the “dieselgate” scandal, and thefor the 2.0d was retuned for lower emissions and therefor, lower MPG.
I will be looking for a remap, that will do away with, or at least, use the EGR less, hence increasing the MPG, not after much more power, as I intend to drive the same.
Any body else agree with this theory ??
