2007 AUDI A4 2.0 TDi TDV SE 4dr Multitronic Diesel Saloon AUTOMATIC

I have recently bought this used car , it has done 90K. I would like to know from the forum guys if they think the MPG I'm getting is bit of the lower side or its alright.

On tank full £90 I am doing 600 miles out of which I would say 500 are motoway miles , my office journey is mostly free run on motoway.

By the calculation its rougly 41MPG which I think is on the lower side , please comment ?

Also what could be the reasons for it , can it be improved in any way like remap ?

On motoway I try to keep speed between 70-80 mostly close to 70 I would say.

if I go get remap what kind of figures I should expect ?

Mines a 2007 2.0 140 PS 6 speed manual and I get 650 to 675 on a tank. You have an auto so maybe they use a little more fuel.
