As I understand it, when the unit reaches the activation limit for the second time, you get the grey message again. A second reset would be tempting fate, but in the OP's shoes I'd not worry about the first reset - there will be the same number of activations again to go, and it's just started. Plenty of owners have the first reset done, and have no problems; actual pump failure is very rare, and I'd not lose any sleep over that possibility.
There will be those that say that the pump could still fail, so the unit must be replaced; my view is that anything on the car could fail, so on that principle you'd better replace everything...
