Hi everybody,
i have a Big problem with my Ford focus cmax and i Hope to find the solution with you.
The problem appeared during a long drive. Passage of the car in degraded mode
Diagnosic of the garage owner: 4 HS injectors + EGR valve except that he did not have the parts to change the injectors.
I had to go home (900km I was on vacation).
the maximum speed of the car was 90km / h
it is at 600Kms that the car got into fault with the engine, immediate overhaul with a bride at 2500- 3000 rpm max
I ended up going home.
I changed the 4 injectors and following a passage of forscan, I noticed a code error: accumulation of soot.
I reinitiated the values ​​taken on by the DPF.
The error code is gone but the engine is still in degraded mode.
So I cannot learn injectors.

I removed the catalyseur DPF . It was hard. The connector between the dpf and the exhaust was welded by the rust !
I cut the screw with a dremel .
I wash the dpf just with water but i don't see dirty water .
The water who exit is clean like potable water. ( Just a little dirty water )
I went up the dpf and i dont have the dtc accumulation of soot anymore but now i have a p244d température is too High on the catalyst but After a lot of erase the dtc, i dont have this dtc anymore.
​​So i tried to go go the road with my car but After the 3rd, i have a dtc p2599
​​Turbocharger charge air pressure control position sensor A, performance problem - high signal....

it is possible that the problem is juste a air admission ?

Sorry for this Big texte but you are my only Hope.

Thanks

Bruno
