Yes a known issue. The float in the switch sinks. Your dealer should be up to speed on this. A new modified coolant header tank required.

Lots of early D3's had a duff sensor in the coolant tank, surprised it's not been done already, dealer will replace under warranty
 

Not so common...

mine did this and tank replaced.

However after it came out of the dealer I still had to top it up every couple of days until the level stayed where it should be. No leak.......but there was obviously an airlock somewhere in the system.
 really ought to change this.........

There is also a TSB for correct bleeding of the coolant system, airlocks can cause 'low coolant' messages even after the cut off VIN for the coolant sensor problem
