sounds like mechanical failure unfortunately, could be a knackered injector, but I would say one should only cause a terrible misfire and poor driving at least...

 

if theres no error codes though, it sounds like there is a loss of fuel or air, maybe spark but I doubt it as much...

well just to let you know my sister got an injector works and no more hesitation on hers... I would take it back to ford for a full diagnostic...will be even better if you can show the foreman the faults.

Just play havok on them, say you have been messed around and there is blatently an issue etc

Doing this my sister and her boyfriend managed to wrangle a brand new fiesta as a acourtesy car for free.

In the end ford werent 100% if it was injector and they dont want to be seen making a heavily pregnant lass pay £££ for something she might not require.

So they took it to a few bus fitters at a local depot and they had it 2 mins and said defo injector (benefits of being a bus driver and them working day in, day out with diesels) they managed to get parts and swap it over...now she said it drives awesome.

What they did recommend was putting some injector cleaner in with some premium fuel as 8 times out of 10 its just a dirty injector and a bit of carbon has come loose.

Anyways keep us posted

Hello again an update on my issues

Third dealer could not replicate or trace fault and went back to basics and changed oil and oil filter. Oil level has risen by a quarter since though! Plus slight misfire returning on warm start.

Got a sample of the old oil tested and very worrying. Lab says main concerns are

TBN three
Viscosity Cst @40º = 36
Iron =100
Traces of fuel in oil

The Lab says all bad signs but cannot comment on effects on specific cars. Any ideas what this is telling me specifically with Focus?1.6tdci?

PTG
