Nedd help! Codes P0299, P0404, P0478
I need some help. I am over in Germany and have trouble with my 2005, F250, 6.0 Liter Diesel, about 45.000 miles.
Overall it does not have the power anymore that it used to have and sometimes when I accelerate, there is NO power at all. Blue smoke and not over 25 mph. After 10 sec or so, it is over and I have power back. Sometimes it takes longer and it smokes like there is no tomorrow. But, when ideling its ok, engine sounds ok.
When I start it, it idles ok. Nothing seems wrong.
The shops over here dont know much about FORD Trucks and I only got some codes from them.
They recommended to change the EGR Valve and said that the codes P0299, P0404 and P0478 might be gone then.
Since about two years there is also a noise if I accelerate and get off the pedal quickly. It sounds like tschtschtsch and I could not really locate it. But it seems to come around the airfilter area. Not sure if that has something to do with my powerloss.
I have to admit that we did not really drive it hard and I saw in the forum that these trucks need that sometimes.
Is there another sensor or part that I should exchange when I order the EGR valve in the US? What else could cause this powerloss?
I appreciate your help very much!
