The suspension on the C5 seems to be electrically operated. When I get in ours there's a buzzing noise and it lifts itself to compensate for my weight. I wonder if you've got a blown fuse.

Is it the front or the back that drops down ? or both ?

did the fault just all of a sudden start or did the front start doing it then the back (or vice versa) ?
Is there definitely no leaks ? are you checking the fluid level when the car is in the low position ? The anti sink valves are built into the BHI unit & controled electrically.
would you be able to park it up overnight & disconnect the battery as an experiment & see if it still sinks ?
