212 gearbox reset

[keith of kent]

For some time when going from "Park" to "Drive" or "Reverse" I have needed to use two applications of the gear selector stalk. One application just put it into Neutral. I thought that it hadn't always been like that and indeed my wife's GLA does not behave like it.( I am aware thats a totally different gearbox.)
In addition I have noticed increased fuel consumption down to about 34mpg ( Its a 2015 E350 9 speed).
I remembered seeing on here about a gearbox reset. Yesterday I did that, when completed there is no indication from the car that anything has changed, I didn't drive it.
Today I drove it and found the gear selection issue solved. The gearbox was changing up at lower revs than it had been of late. The journey that I do twice a week returned 42.8mpg.
I think thats a pretty good result for a few minutes sitting in my car and zero cost

Get in car shut door, do not switch on any electrics.
Turn ignition on, do not start car.
Press accelerator to the floor, hold down for at least 10 seconds.
Turn ignition off, do not remove key.
Release accelerator pedal.
Wait 2 mins for ECU to reset.
Remove ignition key and exit the car.
Gearbox should be reset to factory settings.
