I've used power iso to rip the update CD, ill leave it up for today so get it whilst its hot, as it's a right ****ter to get hold of.
i take no responsibility for what might happen to anyone's car if they choose to use this update disc, the onus is on yourselves if things go wrong, but i have used this disc on my own car and successfully went from 0770 to 5570 with the other discs that are easily found on the interweb without a hitch, good luck
