When I bought my XF new, I thought the spoiler button operation would 'ding' after full deployment or retraction. Now it does not 'ding' any more. Is there a problem with this? I thought if you manually extended or retracted it, when you cycled the ignition (park then drive later) it would be reset. Strange, it works fine, but the 'ding' doesn't 'ding' any more.

Any guidance/help on this issue?
