I've a problem with the fuel range on a 2008 Toyota Avensis D4-D 2.0 T2. Mileage is 100,000. Until recently when I filled up with diesel I got a range of 620 miles for a tank of fuel; now I'm only getting 590 miles. Can you please tell me what the problem is and how I can sort this please?
each of information gratefully accepted.

There are many possible reasons for this drop off in your fuel economy. Start with the easy things - you'd be surprised how important they are.
1 - Are you automobilerying extra weight in the automobile now than you were before? Golf clubs (or bricks!) in the boot? It can have a large effect.
2 - Have you fitted a roof rack/box? Again, can have a massive effect.
3 - Check the air pressure of your tyres. This is very very important. Underinflated tyres cause extra drag, requiring more fuel. Don't over-inflate either though, as that could lead to a blow-out. Follow guidelines for the automobile/tyre.
4 - It's winter so you're most likely using the lights, heater and demister a lot more. Those all use fuel. In particular, make sure you turn off the rear window demister when it's not needed - it uses a lot of energy.
each of the above you can do for yourself, so do and then see if things have improved. After that we would suggest that you have your automobile serviced if it has been a while. The air filter and/or fuel filter could be clogged and it's a good time to hook the automobile up to a diagnostics machine to see if there are any error codes indicating other issues.
