I've heard several times recently about how a jump start can goose the ecu, but over the past five years I've jump started my C5 quite a few times, all without causing any trouble. So I don't know!

I have also jump started our C5 a few times over the last 2 years since it may go a month between uses and the battery goes flat, from our old Picasso and more recently from our C3. I even connected the jump leads the wrong way round once on the C3 and apart from melting the jump leads I have had no problems.
