If it's wet chances are the ESP is struggling to maintain traction, then the light comes on - that's expected. Or do you mean it just stays on all the time in the wet?

if the light is on and your car is in limp mode, then you have a problem with your throttle position sensor (accelerator pedal).
most likely you have a leak coming into your drivers footwell, which has now damaged the sensor on the pedal.
I have exprerienced this twice before.
