I purchased my CLA250 in December. I had been getting gas mileage in the mid 20's. Granted I came out of a 2010 E550 coupe with a lead foot. So going to a 4 cylinder was quite a trade off. But happy with the power and even more so with the gas mileage. This last week if I go in the ECO display on dash when I start the car, it shows from start 2% and goes down to 0%. Previously it started at 50%. I am also not getting the green graph on the acceleration, coasting and ? Forgot last option. I've taken video of this and have an appt for Monday but was wondering if anyone else experiencing this? My overall gas mileage is also in the 18's. I did this with my 550 so my 250 I should be getting better mileage like I had in the beginning. I thought It was my lead foot until I really have been slowing down, and now seeing the ECO display going backwards is making me wonder if it needs a software update or so etching.
