My Volkswagen Jetta shows Error Stabilization Control (ESC)/ABS warning message on the dashboard. The problem first appeared a few weeks ago. At first it only appeared randomly, but for these few days it has been occurring all the time.

My car is still under warranty and I suspect that this is a hardware issue. 

My scheduled service is next week, but I'm concerned that driving the car now can cause further damage to the car (I afraid that this might void the warranty because "I am misusing the car", is my fear warranted?). There is also an issue of whether it is safe to drive this car.

So, should I send the car immediately to the service center? Can I still drive the car in the mean time, will driving it cause further damage?
