On the e39 yes....more so that they just sit moronically low under the car, a good 25mm lower than the front bar so coming in and out of driveways, speedhumps etc....they are always the first to go. Even better is that BMW puts the ambient air temp sensor in the same place, so that is just as likely to get damaged.
Anyway, back OT.
OP - maybe if you just get the clips you might be able to save your original part?
