I would think that as long as they aren't leaking and the fluid hasn't worn out so much that you are underdampened then there would be no reason to service them.
The reason I ask is that Stasis Engineering had some popular coilover kits for Audis that used Ohlin dampers many years ago and those kits had to get serviced pretty often. I think it was right around 2 years or so and then noise issues would start to pop up.
