CITROEN c4 cactus BlueHdi urea

[piki]

Drove the car 2 weeks ago , when got stuck , apperantly the dpf filter was completly blocked and become very red .
After that the urea light went on,conectted to lexia -urea injector short to earth, ordered a new injector , whould throw the same code even after reinitialize in lexia.
when im disconnecting the connector frum the urea injector , the fault chane to open circuit-so tha mean the wiring are not short to the body.
is the urea eco toasted? any ideas?

Not sure I understand what you mean by 'eco toasted' ?

[Paul-R]

How old is the vehicle?
How many miles has it done?

I don't know what 'eco toasted' means either!

[PaulC5]

Is the exhaust tail pipe white inside from too much adblue being injected ? Just trying to think how a urea fault and a blocked dpf could be related or has the injector wiring been damaged by the hot dpf.

ECU toasted? I.e. fried..

Sorry guys .....
its 2018 done 220k km.
when the dpf was clogged . i stopped on the side of the road , and it was glowing red then the car whould start to give the urea fault, then when tested the injector, it wont give any resistence, so i replaced it with diffrent one.
my question was -if when a good injector is pluged in lexia show - short to earth,and when the connecter disconnected from the injector lexia show-open circuit, so that means -urea control module (or something like that ) is bad? what are my options? i tested with 2 working injectors...
the tail pipe is black . there is no white there....

The Urea Injector electrical connector requires a very firm (hard) push to correctly seat it. It is easy to get this wrong. It can feel like it's home bust isn't. You should hear a distinct click from it when it's properly home.

So why would lexia read a short ,if connector won't seat fully lexia would stay stuck on open circuit fault
