citroen c3 1.1 programming second ecu

[mellon]

Hi. I have problem with citroen c3 1.1. I need new ecu programming because the old one damaged by water. I bought a second with the same numbers from used car. This is IAW 48P2.72 (HW is the same). How to do it in the simplest way. I know only VAG Group I have no experience in the PSA. Do virgin ecu programming flash memory, or it can be done somehow by Lexia (I can buy this programmer). I know the immo pin into the car and this also to bought ecu.
Best regards
Adam

hi, the simpilist way 2 do this is 2 swap the processor from ur old ecu on 2 ur nbew 1. on a iaw 48p2 ecu the processor u need 2 swa is 29f400bb. this holds the immo data alsop car will start, i done 1 of these cars this way just b4 xmas

Read 29F400 from ecu and post here.
Also if flash is not damaged from old ecu you can swap between

I change eprom flash but don't start. Ok. I write the whole story. The car did not run it and it was an error on the stepper motor. New and original stepper motor did not help. Cables checked. The Ecu was a little trace of water. I bought a whole set of BSI, ECU and keys to the pin. The car worked. Dash is not because he is assigned to BSI I think so. Still errors on a stepper motor and the injectors yet. Errors after erasing a comeback. I came up with that read the memory of the original BSI and program it bought and I try on the old ECU. The car did not run it. I write to BSI purchased the original content. I stuck bought a set of BSI, ECU and transponder. Car not run. On the oryginal set of bsi, ecu the dash is OK but still not working. On bought set of componets dash not working and car too.
Well, I have a problem. I think I bought the ECU is good because the engine fired on him. And I did replace the flash memory before installing a whole new set. Maybe the original ECU has damaged the contents of memory and, therefore, after replacing the memory did not want to fire.

Files from BSI original and the new one. I have to read even a flash of the ecu.

Check if you have the black condenser connected to the ignition coil plug(+12v wire, i think the red one), and the condenser is in one of the ignition coil screw (left one, if you are inside the car).

If not, injector error could come from that, because parasites, you need to solder the condenser wire the most near ignition coil plug.

I know this will not solve your non startimg problem, but is something

Did your check wiring? Battery acid could damage the wiring under the battery.

Condenser is something like this:

HI. But on original ECU and BSI I only have one error on stepper motor. I new BSI, ECU the car run for first time but I have 7 error. The problem is that after my combinations car stopped working on purchased components (form other working car)

Better to virginise the better parts (ECU and BSI) you have and program everything as new.

What can you say about immo arameters in Lexia:

ECU matched with BSI ?
ECU unlocked?
Key recognized?

How much injector errors you have, and what cilinder?
I think one or two injector and stepper motor error shouldn?t be enought car don?t start.

Do you hear electric fuel pump start when turn ignition on?

About dash, could be coding, i know there's one parameter you have to change in BSI, if dash don?t work, don?t remenber what, BSI is same reefrence, only have to change parameter.
Check client options in BSI, i think...

Hi. Thank you for your reply. Today should have Lexia and I could check everything. Until now, a colleague came to the KTS. I have only VCDS and OPCOM so I can not too much work with Citroen.

Real toughts are with Lexia
