Hello   I've recently purchased a Citroen Xantia but unfortunatley it didn't have the manual with it.   I need to know how to change the start code.  I think the default is 1,1,1,1  - problem is, the 1 is on it's way out.  Can anyone help?   Also, the dash light seems to have gone very dim, is there anyway this can be turned up?   Thanks  Tanya :unsure:      ps... maybe someone has a manual they could share?  :rolleyes:
