Hi everyone, just bought a 2006 307 2.0 HDI 136hp as a non starter,
here is the problem:
the engine wont turn over when i turn the key, i have tested the starter motor and it works fine, however, when i run a wire from the battery + to the starter motor it turns over but wont start, this means the starter motor is good, but the car wont start?
i have done a diagnostic check on the car and its coming up with a few faults, mainly:
on the engine ECU test: it comes up with, engine control unit locked: yes
however, on the immobilser code, it says transponder code correctly recognised and all is matching ok
on the BSI test it comes up with: No communication with the engine control unit
the car has been damaged on the front nearside, which is where the engine fusebox and ECU are located, however, i cant see any obvious physical damage to these two
i am not sure if the fault is with the BSI or the ECU, any ideas how i can find out ? i guess i can use the same second hand BSI just to test and see if the starter turns ?

here's a capture of the diagnostic results screen ( as attachement ), please let me know if you can help..
much appreciated
thanks

Hi, i have checked all fuses in the BSI and also engine fusebox, however i will double check again tomorrow, what is fuse 8 for?
No, no comms with abs/esp unit, there is comms with all the rest, bsi, engine ecu, air con....etc but not ABS
ps: i have also swapped the main relay situated near the engine fusebox and that hasn't changed anything.
Also, both front windows won't operate, but the rear ones do

thanks for your reply

hi,,,
so fuse 8 is good??
is it powered when in start position?
what parameters can you see for start auth in bsi???

what is this main relay?? near ecu??
i can think of only
glow plug relay or if attached to ecu cover then it's the abs relay from the recall mod.

hi,,,
so fuse 8 is good?? YES
is it powered when in start position? NOT SURE, WILL CHECK LATER AND LET YOU KNOW
what parameters can you see for start auth in bsi???
NUMBER OF KEYS LEARNED: 2
TRANSPONDER CODE RECOGNISED: YES
BSI MATCHED: YES
KEY IN THE IGNITION POSITION: YES
ENGINE CONTROL UNIT LOCKED: YES ( AND THIS IS THE PROBLEM ? )


what is this main relay?? near ecu?? ON THE ENGINE FUSEBOX PLASTIC TRAY, IT IS CLIPPED ONTO IT, THIS RELAY POWERS THE ABS MODULE, AND WITHOUT IT THE ENGINE WOULD NOT START
i can think of only
glow plug relay or if attached to ecu cover then it's the abs relay from the recall mod.

WHAT I CAN UNDERSTAND IS: IF THE ENGINE CONTROL UNIT IS LOCKED, THE ENGINE WOULD NOT START
ALSO, WHY IS THE STARTER MOTOR NOT TURNING ??

any more help would be much appreciated

I KNOW THAT WHEN I TURN THE KEY, IT DOES RECOGNISE THE KEY BEING IN THE STARTING POSITION
OTHERWISE, WHAT AM I LOOKING FOR IN THE PARAMETERS, CAN YOU TELL ME WHAT I SHOULD REALLY LOOK FOR IN THE PARAMETERS?
THANKS

[quote="toddy";p="46230"]hi,,,
so fuse 8 is good??
is it powered when in start position?
what parameters can you see for start auth in bsi???

Hi, i have checked again the car today:
Fuse n:8 in BSM is good, it is ON constantly, even when the key is not in the ignition, so it is permanently live, and yes it is powered when in start position
However, Pin n:2 from the 5pins connector in the BSM ( pin 2 is for the starter ), is not powered when in start position, but when i disconnect the connector, and i check pin 2 in the BSM it is live ??
not sure if this indicates something ?

Also, still no comms from ABS/ESP, however the ABS pump is not present so maybe thats why ?

and i have scanned the car again, and under ECU parameters, it says:
-Problems detected when transmitting the unlock code : awaiting response from BSI

Any ideas please
