N57 - New intake - 48.5 mpg

2013 F25 X3 35d Got a new intake due to an issue during the egr cooler recall, paid for by bmw I also got a software egr delete afterwards to preserve the new intake.
Before this my best mpg was 34-37 mpg with cruise control set
To 70 mph. Last two days I covered 510 mainly motorway miles and still have a quarter tank left. Cruise set to 70-75mph with a few blasts on sports mode. Pls clean your intake! At current fuel prices it will pay for itself!

This sounds identical to my experience (as posted). Have you confirmed the economy after a fill up with miles run on tank?

I appreciated a reply from one subscriber about adjusting dash economy readout but hesitant to get into the hidden menu. Any further advice or direction from anyone on this would be appreciated.

Yes this is based on a full tank followed by what is now 550 miles with under a quarter tank remaining.
