Today I had a service and had my side lights changed too, I had to have the battery out to get to the side light on passenger side. When I filled up with diesel after it I filled the tank to the brim and now my trip computer says I have 265 miles in the tank where as usually when I fill up it say about 460 or something like that.

I've tried to give it chance to settle but it's staying the same! What's up with it does anyone know?

Cheers,

Jamie

P.s. sorry if this is in the wrong place admins! I'm not sure if it is

I presume that removing the battery removed the info the car had on your mpg and so has used a default to calculate range. Just a thought.
