This is the closest ecu I could get. It's from a HDI and myn is petrol but it's very close

Arfur is there a step by step for getting that centre plastics off that's connected to gear shaft? And how do I disconnect the lighter plug and 2 window buttons?

[00James00]

Ordered an ecu from eBay, will need to know steps to get to ecu, I know where it is and seen it but had trouble disconnecting window button and electric socket. How do you also get that plastics per past the gear shift. I disabled all the configuration like you recommended and try to see what faults would erase but they all still remain. Also looked into updating BSI through the downloads option and got the warning sign in picture, I do not have the original key codes for the car

Took these as well.

If you find you need the key code there are websites you can get the code from, this is an example click here.

No recommendations for this site (or any others), but if you find you need to go down the BSI reload route you'll need the code.

Should you get a code you can verify it before reloading software by entering one of the functions that prompts for the code.

Thanks for the reply missing lincs will also add this to my list of to do lol

I noticed on my screen shots that ECU has no in dialogue box my car has power assisted steering and it also works fine but why does its state no??

and there is also this picture in that topic

a date of 00/00/00 looks like the first and only BSI download. That would suggest there is another available




and this is very clear

Its a shame you didn't check that everything was with the car that should have been, but then again you wouldn't have been able to test the code before you purchased the car.

f you find you need the key code there are websites you can get the code from, this is an example click here.

Great !!

Should you get a code you can verify it before reloading software by entering one of the functions that prompts for the code.

Very wise

I disabled all the configuration like you recommended and try to see what faults would erase but they all still remain.

They need to be read and cleared. Each one in turn. Maybe this doesn't work, but I am surprised. Are you sure you are erasing the code?

Close is good.

Hi thanks for the information, yeah I'm going into the airbag ecu then reading faults, then going into erase faults but it says faults still remain after erase screen.

I can't see anything about front satellites in the description does my car not have these.

I have some AIR BAG pictures to keep the topic AIR BAG related

The C3 is a 2002 and has side, front and passenger air bags, but no curtain ones.

This is the side impact air bag

and this one is where the curtain ones would have been identified (in the oval)

This is the LEXIA configuration for this car for AIR BAG

air bag configuration.

and this is the BSI configuration for enabling the AIR BAG ECU communication.

Hopefully it is of some help to you.

Thanks for that, when going into airbag ecu mine has three different sections front airbags, side airbags, and pretensioners, the from left and right satalite? Would these be enabled in my car? Would my car have these.
