Help have anyone had a problem with car completely dead, battery seems charged but car says vehicle electrical fault rac guy says he thinks its either battery but seems to test ok and has had it connected to his van to give boost but still nothing or its suddenly showing loads of fault codes. He thinks might be body control module or the battery.

Try getting out, pressing the lock key twice in succession, leave 20 secs and see if it’s any better. Mine did this a few times, always self corrected.
