I’ve had my GLA for just over a week and it’s meant to get 50 mpg but at the moment I’m only getting 25 mpg , Will this improve ?

Probably not! Honest John website gives real user averages for each model. Mine is 250 4matic auto and I just about beat the average for that model but that's as good as it gets for combined result.
On a long motorway run in eco mode I can get over 40mpg but I normally drive B roads hence my much lower average.
