Hi there, my brothers x reg, 1.4 306 failed it's mot on emissions, they replaced the coil pack to fix a misfire but that didn't sort the emissions, they then tested the lambda sensor and that was fine, they deduced it was a problem with the ECU...
We also had it tested by an electrician, he concluded that the wiring was all ok, however there was no switching voltage from the ecu/lambda circuit. Internet research said that the Sagem coilpack can sometimes cause voltage spikes and damage the ECU, but this has now been replaced with a bougicord coil pack.
I've been looking at the options:
1) Buy a new one... £750ish from the dealer... (not really an option!)
2) Get a reconditioned one in exchange for this one/get this one reconditioned... £195 from ecutesting.com
3) Buy one from ebay, probably from a breakers... between £20-£90.
My main question here is how important are the numbers on the ECU... There are three stickers:
The first says: PROGRAMME SL96-9 601300 140598, the last number varies on ones I've seen on ebay
The second says BOITIER INJECTION *9632520280* PSA, this is the same for all other ones I've seen
The third says SL96 21649399-3 IND. MOD. : F 0058465081, other than the SL96, the other numbers and info varies
A few examples are:

http://cgi.ebay.co.uk/CITROEN-XSARA..._CarParts_SM&hash=item1c1ab3d786#ht_674wt_905
Also, is this a straight forward plug-and-go ECU or is there any element of it which would need programming in, i.e. the central locking?
Any help/info would be great, sorry it's such a long post! Thanks very much
