Have O5 plate td4 if you floor it or go up a hill in any of the gears it puts the warning light on on the right of the dash the engine one with a ! in it and lacks power.

if you ease off the light goes out hasnt logged any fault codes. it will also put the light on if you floor it at a stand still and it wont rev higher than about 3500rpm

have cheched all turbo pipes and all seem fine. if i take the vac pipe off the turbo actuator it makes no difference.

Any ideas? thanks
 
sees to be getting worse i have tested everything i can think of i have plumbed in gauge in low pressure fuel line if i dead head the pump i will get about 4 bar.

but with it running i get about 1.5 to 2 bar if i rev up the engine the pressure drops to nothing and then fault light is on and engine will only rev up to 3000rpm.

if i leave ignition on till pump stops priming and then start it will rev round to limiter for short while.

so i think the low pressure pump has failed any ideas on what the pressure the pump should kick out with engine running?
