C5 X7 - windows only open with engine running

Is this 'normal' behaviour or is this the 'Economy Mode' kicking in?
If it is then I will have a go with the battery testing on diagbox

Yes, normal. You may get a few seconds of operation when the ignition is switched off, then power is switched off to avoid battery depletion.

Try running the radio with the ignition off - if it switches off shortly after - you may get the economy mode message which means the battery health is not deemed to be great.

Mine always kicked into economy mode very quickly, even with a new battery.
