Re: Help required please

I can't see it being that badly blocked with no message or error light and I can't see it starting and then immediatly stalling (although the exhaust pressure would quickly rise on starting), also I do plenty of long runs in the vehicle. However that being said if there was an error stored for soot loading it wouldn't perform a regen on its own and the last time I noticed it doing a regen was at least 500 miles ago. I have heard that a forced regen will remove about 10% soot loading?
they've had it since Saturday and they say its started fine everytime, I will know tomorrow morning when I start it.

Re: Help required please

Car has been totally fine since collecting on tuesday and the vibration that I also mentioned seems much better, shortly after collecting it did a regen for about 5 minutes but hasn't since.
May look at getting some way of checking the soot loading for future reference as my scantool doesn't seem to work with Fiat although it does with every other car I've tried it on.
Thanks for everyones input :-)

Re: Help required please

Typically the car started playing up again on Christmas eve; same as before starts on the money, runs for several seconds then stalls, then after resarting is a bit hesitant driving until engine warms up a bit. Also injectors are quite noisy or it could just be diesel knock.
Had all the inlet off this morning to check all the pipework etc. not really found anything too awful, except the the breather that comes from the back of the engine that joins the inlet pipework before the turbo was full of water/oil (I.E creamy coloured gunk).
Took the return pipe off of the HP fuel pump (before doing anything) and on activating the lift pump just diesel was coming out i.e no air, with ignition on for 5 seconds it pumped 1/2 litre, so don't think theres an issue here.
The only other thing i noticed was that the compressor on the turbo had been hitting the casing (where the suction pipework goes) it has polished the inside of the casing up however there doesn't seem to be any damage to the compressor.
Happy Christmas all

Hi,
If the turbo rotor bearing has enough play to allow the compressor to touch the housing it needs replacement. You can buy just the rotor and bearing as a "cartridge" that you fit the existing housings to for under 100. If you leave it too long it will only get worse. You may have a cooling or oil supply issue that is the root of the problems. I'd suggest you get a coolant pressure and head leakage test (detects exhaust gasses in cooling system) nd a oil pressure check before spending too much more on the car.

Re: Help required please

Hi,

Been back to dealer today and they've agreed to let me have another vehicle, so have gone for a Ford Fiesta ecoboost.

Thanks to everyone that has offered me help
James
