Hello guys.
I have a slight problem with Peugeot Boxer III 2.2hdi 100hp with Visteon DCU-102 ECU. I got the ECU bricked during OBD write because of the laptop crash.
There was no response through the OBD anymore so i had to reflash it in BOOT mode with the OBD read flash + added RAM 64kb full with FFs. Now I can communicate with the ECU through OBD but the engine start is blocked by immobilizer DTC U0426. Already made the dump virgin, reflashed it, left it for 20-30-50 seconds with ignition on but still the DTC is permanent.

Any ideas? I read many posts about virginizing Visteon DCU102 and engine starting right after reflash but in my case it seems a lost cause. Do I have to readapt keys with Lexia/PP2000 or it has to self-adapt?

Sorted!
It is a myth that if you FULLY virginize the ECU the BSI will self-adapt to the ECU.
You only need to virginize certain areas of the Visteon dump and then the car starts without the need to recode injectors, rail pressure sensor and etc.

Of course i will.

9666484580-ORI - this is the file downloaded in boot mode - a file with keys,rolling codes, rail pressure sensor calibration, injector codes etc.
9666484580-virgin - this is a virgin file enough for the vehicle to start with still the keys and other stuff programmed in the dump. Actual virginizing is the part where the differencies to the ORI are FF. The other differencies are some calibrations which i cannot actually define.

So to be easier to understand - if you have a Boxer/Jumper or whatever crap with Visteon DCU102 with SW Version 9666484580 you can upload 9666484580-Virgin.bin to your vehicle and it will start right away. If you upload 9666484580-ORI - the immo will become locked because there are some parts already fulfiled from my BSI to the dump.

I hope this helps someone in a same mess as i was 2 sleepless days :)
