Hi
even if someone will disable P0A09 and still you can not start the engine
check harness for broken wires from injectors

Nice, question is why?

Justy over to you

[alessioblaupunkt]

Did they try to start the engine with cables?
Did they reverse cable?

Had one similar case in a Merc-A-Dies but ECU survived, the confort control unit died.

Hi friends

I've been searching for an ecu, and what happened is that my car is 1.4, but I find ecus 1.6 tdci with the same reference.


How is it possible?

Hi
if hw 5WS40585D-T are the same you can use it without any problem !
just read original ecu and paste file in the second one

Hello,
I have a 2007 Focus 1.8 tdci with same problem, haven't found any broken wire. Any sugestions pls...

[dimitar]

Check wiring and measure resistance at the injectors between terminals and ground

Between terminals aproximately 200kohm

Between terminals and ground should be infinite

Think got the same issue...
