Mine's exactly the same, around 20mpg and no power. My one is especially gutless when cold though..

A TDi manual gearbox Disco should deliver nearer to 30 mpg overall.

Give the car a full oils and filters service inc the air filter. Clean out the fuel sedimenter. Check tyre pressures 32psi front 36psi rear. Check to see if any brakes are dragging?

My 300 with manual box gave same signs, changing the fuel lift pump helped a lot with both performance and economy. Test it b by whipping off the hose on the output side and cranking the engine over on the starter - check the flow rate - mine was not flowing ANY fuel at all. Disconnect the stop solenoid on the injection pump to prevent the engine starting while you do this.
