new noise in my 2003 v12
While driving heard this loud chirping sound from under hood. Eventually stopped. Later locked the vehicle and it beeped for about 2 minutes. Also while driving hitting a bump vehicle 'chimes' and a red indicator flashes quickly in the dash. New to the forum, appreciate any guidance.

Is the red indicator the abc warning ?a quick flash of the indicator going over bumps usually means the abc system pressure falls too low
The most common problem is the accumulators . Check your abc fluid to see if it is low. If it's low and there are no Leaks externally then one or more of the accumulators had failed and filled with fluid instead of their nitrogen gas charge : it could also be a squeaking abc pump unable to maintain system pressure over bumps
Accumulators are Cheaper to replace than the abc pump so those would be the first things to check
