I have a MK1 focus estate diesel that I use for work and its developed this problem in the last few days.
When I accelerate the thing doesnt want to go and accelerates really slowly until it hits the turbo.Its like there is no acceleration from zero to 1800rpm !
Any ideas people?

Is it smokey? Check for split boost hoses or vacuum lines around the engine, they are quite common to crack and split.

 

Ah.not yet.
Cheers

Agreed - (split boost hoses)

Also check EGR valve (bung a blanking plate on it, solid, stainless steel - fiver online)

And if its a variable vane turbo check its working properly (variable vanes can coke up & sieze and can have a knock-on effect on the actuator etc )

Worth sticking a code reader on it - if you don't have one (f- super is about Ł20 online)

 

Changed the filters (diesel and air) but still the same.
Where about is the EGR and what does it do?If I blank it will it effect the running?
Thanks for the advice.

EGR stands for Exhaust Gas Recirculation, a little of the exhaust gasses are recirculated into the inlet manifold, controlled by the EGR valve (electronic or pnuematic) from the ECU

Theoretically this reduces emissions, in practice it contaminates the inlet manifold with carbon/ gunk and if (when) the EGR sticks open, clouds of smoke and/ or poor running, even if it is working correctly it can cause flatspots and hesitation

Blanking the EGR valve (solid, stainless steel plate) can fix a faulty EGR valve, prevents further contamination to the inlet manifold, and can reduce flat spots, hesitation

Blanking an EGR vakve should not cause a UK MOT failure, (only particulates(smoke) is measured on a diesel) and can often actually help

On some Euro 4 Ford engines, blanking the EGR can cause the EML (Engine Management Light) to come on, (amber coil) this is about the worst that can happen, this can be ignored or reset with a code reader - i think yours is a Euro 3, so this is unlikely to happen

If you have the 1.8 TDCI, i think the EGR valve is on the inlet manifold on the back of the engine - you put the blanking plate between the EGR valve and the inlet manifold

 

Blanking plate on order...lets see what happens now.

check the hose that goes to the turbo have known them to get contaminated with oil go soft then they collapse so u get no boost or loads

 

cheers,will do.
