I filled up my car for the first time today and reset trip A (also both the fuel gauge and app both showed fuel level as being full)
According to the car I've averaged 38mpg over 77 miles and that's with a mix of motorway and urban driving.

34 mpg based on receipts over the first 250 miles - mainly local mileage. I will be happy if it is between 35 and 40 mpg when run in and doing mixed local/motorway driving - and I am using the power periodically.

Recently 245 miles to Brighton cost £ 29 in fuel - one way with two up - so half the cost of a cheap train deal.

Now up to 970 miles and the engine is freeing up and it is also noticeable how much better the brakes are becoming.

Filled the Astra up yesterday. The fuel gauge was dead center (1/2 tank). Doing 3 really slow clicks I managed to get 16 liters in.. The needle of course didnt show full. If the tank is 48 liters, then the first half of the gauge quals 1/3 of the tank. No wonder it first drops like a stone and then doesn't move.

Major update!

I've just got a call from the dealer. They will be swapping out my fuel tank and hopefully it will solve all my problems! Thankfully I was already booked for annual service next week and they will do the switch that day. Otherwise I would have had to wait at least one month due to fully scheduled mechanics!

Good luck with that, just had my tank changed and it does now read full on the app at 51 or 52 litres, but I'm sure it's still only got 48 in it. 1st fill after getting car back needle just below half, app reading 25 litres. Got 23 in, app showed 51 and full. I think at this point my maths is better than that of the car.

I picked up the car with 5 km. They said they put 5L in and gauge was just above empty. Went to petrol station 2 km away and the guy poured in 44,43L. Gauge went to a little more than full.... we ll see how it goes down

Finally got round to checking mine. Reset my Trip A when I filled up in Bournemouth last week and noted the mileage. Just filled up this evening and Trip A was at 39.3 MPG, but calculating it myself the true MPG was 35.1. Once I had filled up I checked on my app and the tank was reading 100%, so I don't have an issue there. My old vectra also used to tell me the MPG but I always just accepted it and never thought to double check, so for all I know that could have been out too. I was lucky if I ever got over 25 MPG in that over a whole tank.
