Apologies for the AND instead of AN in the title - doh///////////////// ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Ok, so if you ever have an issue with your L series ECU / DCU, then you cannot just replace the engine management 'box' it has to be 'coded' to your system
IF you know someone with appropriate soldering / re-flow skills then simply get another ECU (ebay etc) (make sure it is the same part number ! - there are only two AFAIK! )
.. and then remove and replace - or get some else to do it - the two small 8 pin eeproms. marked 93C46 as per the images

That's it - DONE - - the ECU is now an exact clone of your original ECU even down to the immobiliser system etc. MANY places have what is called 're-flow' soldering equipment. Any radio / small electronic appliance (TV video dvd computer etc) place should have all the 'stuff' required'
Job sorted.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
This is - 'Not' for everyone of course
- but FAR - indeed - way - cheaper than sending it away !. You can get second hand good ecu's from Ebay or breakers etc for little money. The work in the changing of the two 8 pin SOIC chips should only cost about 30 to 40 quid depending on hourly rate .. so away you go.
I would also be fully prepared to do this for you if someone needed it (but note I am in Portugal so allow for postage delays!)
... or, of course I could help and advise where possible anyone who wants / needs to do this.
Hope it helps someone. ??

ps - if you have the equipment yourself to remove and replace the 8 pin soic eeproms, then you probably have a programmer - if so then copy the bin file from each chip and then you can blow the code to the old eeproms and have a completely spare 'clone' unit'
