Have there been numerous examples of this happening then and it being confirmed as an ECU re-locking itself?
I only ask because the soft-unlocking as I described above is the way 95%+ of 205/309 conversions are done and I've not personally heard of any re-locking themselves. There's an awful lot of converted cars around these days between GTi-6 and 2.0 Turbo swaps that have become common since the supply of usable with a costly rebuild Mi16's dried up a few years back.
Probably not in 205s - that's because there's no BSI to say to lock it, when you do it in a 306 you're more likely to, since it's the BSI is what tells the ECU to lock. You can do a soft unlock then snip the comms line in the ECU that's from the BSI - that'll stop any comms going on which may relock it.
Best way is to flash the immo chip in the back and totally unlock it - one day when I get time I'll figure it out and let people know how to do it, if it's anything like the 5p08 chips in the back of the single plug HDi ECUs, you just need to reflash the clip with an SOIC8 clip pretty much a 30 minute job.
