Hi!

I need help with the EGR off.
The car Ford Focus 1.6 TDCi 110hp edc16c34

I closed the EGR (hysteresis solutions), but I get an error code p0407, because the EGR bad.
There is EGR switch in this file?

my last post could be the DFP.

needs confirmation.

I can only install the car this weekend.

the EGR valve is connected.
It is possible that the only solution is to turn off DTC.

why are you closing egr valve ? is it faulty ?

if is it faulty it needs to be switched off and disconnect the cable...

when using egr hysterisis maps to close it you only say to the ecu that you want to keep it closed, when you turn the key on she stills does auto tests, if she is clogged, may stay open and car will stall, or be lack of power or trough a DTC....

Yes, the EGR valve is it faulty.

Yes,
but I can not find the EGR switch.

1E7849 - Switch to enable particle filter

does the dtc gets car to the limp mode, or just a light on the dash? if you don't get the limp mode, it's all right just to turn off the dtc in hexdump, but if car goes to limp, there is a need to think of something else..
