Hi
My TD5 Disco has started to hesitate when accelerating (even lightly) when heavily loaded at high speed, i.e. greater than 70mph. Is this a sign of fuel starvation (fuel filter, fuel pump), or something worse/more expensive?
Thanks Ian...
Air? I was told about an air sensor (on top of the air intake on a Defender) that could cause that when not working properly.
Hope this helps.

Could be the old problem of oil finding its' way into the wiring loom from the injector end. Eventually works its way back to the ECU
It could be lots of things, but a quick plug into TestBook might help - I'm thinking that the Throttle Potentiometer may have a fault that needs clearing.

It is most likely to be the airflow meter that needs replacing. Loads of these go out of range when you floor them. This results in the the TD5 ECM momentarily seeing a 0 reading for the air mass and the engine hesitating.
It won't be the throttle potentiometer, as you would experience the hesitation at different speeds through the gear range.
As Richard says, plug > >
Thanks to all for some great ideas. I'll give them a try.
