Ford Focus 1.6 Tdci (109 Ps)

7 posts in this topic

Hi,

First time poster long time lurker :)

I recently purchased a Ford focus tdci 1.6 it is an 06 plate. During the first 2 months of ownership i have had no problems. However, since then an EML light appeared indicating a DPF fault. The car was returned to the original seller (several times) and eventually a new DPF eventually fitted. They also fitted a new EGR valve. The reason that I would like your advice is beause

when driving down the motorway I am experiencing intermittent power loss . It is almost like the car is kangarooing like a petrol model. I am thinking this may be a MAF sensor fault? I have also noticed that the breather pipe from the oil exchanger is a poor fit thus causing oil vapor to collect in the air inlet (from the airbox).

Now onto Chapter 2: When i got the car after 2 months i noticed the "black death" from injector 3. There is a fairly small, but noticable carbon deposit coming from here. When i returned the car because of the DPF fault i informed the sales man and he ensured me that the injector seat has been fixed.

However, I am now 6 months in and still experencing this kangarooing type problem with the car.

I have looked at the turbo chaft and it is solid and looks to be Ok.. Have also taken off the EGR since it has been replace and it is free and working as should be. Where else do i look?

Your thoughts and suggestions are most welcome (except i can't afford to get rid)

Pete

Did you ever find the cause of this problem?

Buy a EGR blanking plate, has it had a service ? Fuel filter regular change is a must as is oil and air but the fuel filter is known to cause problems. REGULAR servicing with GOOD quality oil is another thing. BUT .....NEVER overfill the oil as this can cause surging acceleration when driving.. :D :driving:

I've had it serviced, had all the filters changed oil, fuel, and air. 5w-30 dex052 engine oil to the correct level. I'm going to blank off the egr asap and see what happens.

Thanks for the reply.

What would be handy is a decent list of potential causes for turbo failure. Less obvious one I've heard of was back pressure from DPF.

I know its just low oil presure to the turbo, I don't have a problem untill I drive the car very hard, then I can hear the turbo squeal because not enough oil is getting up there, hence I just potter at low revs all the time now.

The next thing to look at would be changing the oil pump but first I would like to fit an 'Oil presure gauge' I don't know if anybody has done this but will ask if can't get an answer anywhere else.
