Replacement computer/BSI anybody?

Hi folks,
My wife's C3Pluriel 1.4 petrol semi auto failed to start yesterday. I've had it down to my local garage (not Citroen) and the mechanic has done all the re-set procedure's and ran several diagnostic checks however they were all showing lots of fault codes of different kinds and his feeling is that the BSI itself has developed a fault.
Any suggestions on what I can do to remedy the situation (short of crushing it) would be gratefully received.
Thanks, Jed

Well, a second opinion may be helpful?

If you list the fault codes here, it may help because they may all be related to one fault!!

Which are 'permanent'? which are not? Is it an immobiliser fault? Does it turn over? Is it in 'Eco Mode' yet?

Are they all BSI related faults, or engine or can bus? If its a bus fault, changing computers may just not fix it.

Check the BSI is not full of water......

Changing the BSI is the last option, check fuses and connections is your first.

If you do want to change the BSI eventually, you will need to change the BSI, the engine ECU and the circuit board from the key to get a fully working car (assuming the BSI is at fault). Match ECU from the same engine and BSI from a similar year, make sure you get at lest one key. If you pick a BSI from a different specification car, you will need to do lots of Lexia programming, have a look this ebay link for a kit which come up every so often.
