Can anybody tell me if these BSI units are interchangeable for instance
if bought second hand. I know they have to be re programmed but
do i have to get the precise Siemens part no that is on the unit. any help
would be appreciated

You CANNOT reprogram a 2nd hand BSI unit.
Go buy a NEW one from your Peugeot main dealer.
OR
Get your old one tested / repaired by BBA

Why can the old one be reprogrammed but a second hand one can not? Are they not physical identical?

Something to do with a security code in the ECU for the BSI to communicate with. It cant be changed, and the ECU and BSI have to have the same code.
I think...

You cant reprogram the old one either.
The only things you can do is:
Update the software version
Reconfigure the BSI setup
Recode keys
The VIN number & mileage are extremly difficult to alter / tamper with.
A brand spanking new BSI from Peugeot is cheap enough anyway.

I see. I didn't realise a BSI can only be programmed once. I hope I don't end up going down this road anyway. Will have to see what the auto electrician says.
I take it the OP's is bust?

Mileage is easy enough to change, if you have a programmer
You can virginise a BSI, but its just too expensive because you need to change some of the eeproms and then recode it all, its cheaper to buy a new one and recode it.
If you get a second hand BSI, and remove the coding for the immo it will work.

Thanks for your replies just one question puzzles me. There must be over a hundred second hand units on EBay for sale. Why would anybody buy these units if they cannot be recoded. I checked with BBA this morning and they can rebuild faulty units and give a 2 year warranty for approx £100 but I didnt ask them
how quick they could do it.

Why are you buying a new BSI?
They work with the corresponding ECU and transponder, or if you remove the IMMO

Getting it looked at by someone that knows what there doing for a start.
Just throwing parts at it in the hope of fixing it shouts " I aint got a clue what im doing "

It could easily be a broken wire or bust relay. My battery spazzed out my electrics and bust my electric windows, I need to get my car running right first but the BSI is not the first place I will be looking as it is the most expensive.

Isn't this a bit like using a sledgehammer to crack a nut?
