Hi,

I'm new to this forum and have been reading with interest the thread about this fault code.
My car has the same problem, I'm beginning to fear that it just means that the engine is a bad construction, on the other hand I cannot understand that if that was the case, FORD would have sold so many of them...

When driving in the city or country roads I do not seem to have the problem (constant changes in RPM), only when on the highway and especially after quite some time on cruise control, when I then need to slow down for a moment and I just press resume on the cruise control to go back from about 100 to 120 the glow plug light begins to flash, the power drops and before I even reach the emergency lane at the right the engine has already stopped running. Contact off, on again and it starts (although sometimes with some effort), then I have to launch, give some power of course to fade in with the traffic and then....AGAIN the same. This car is realy unsafe. I have tried in manual (I have an AT 5 speed) and when I drive on cruise controll I just sometimes push him in 4, and then back in 5 to avoid the same RPM too long. It helps a bit, but not realy.

I had the fuel filter replaced by a new one, the residue that came out of the old one contained slimy things (probably because a certain percentage of diesel needs to be BIO diesel in Belgium (so I've been told)) and also water.

In a couple of days I will again check the stuff that comes out of the fuel filter. The mechanic in my dealer ship fears that a complete cleaning of the entire fuel system (tank and all) might be necessary when we see the same stuff again in the extract from the fuel filter fluid...

I bought this car second hand (from a private person) and my dealer also informed me that all 4 nozzles are new ones and that the EGR inlet is closed. So I suppose I bought the misery from someone else. Can somebody make me wiser why the former owner would have closed the EGR inlet? What is the (expected) advantage of this? My dealer wasn't sure why but told me that this would not cause the problem because it still is the engine with a vacuum system (don't ask me further explanation about this because I'm only a poor user not a mechanic)

Realy regret this problem because for the rest the car is a dream, full option, spacy etc. (and nice looking but this of course is subjective)

I wonder why the EGR is closed and whether that could cause the problems I have?

thanks in advance for feedback,

brgds,

Dirk
