Hello everyone! I have a code P203B and U1140. While driving one day I got a message on my screen stating " AC and Chiller functions are temporarily disabled. The car drove with no symptons of having a issue. The AC blows nice and cold and at full power. Car does not overheat or anything. One thing I did notice was the humming noise coming from the engine compartment under the coolant resovoir by the cold air in-take filter. The humming stopped after about 30 seconds. Took the car to the shop and at first they couldnt find a problem. So they reset the car and called me to tell me what they did and no codes came back. When i picked the car up the engine light came on immediately when I tried to leave. I pulled it back in the shop and they hooked it up a code reader and then they tell me the pump is bad. Could it possibly be sometjing else. Forgot to mention after they reset the car you can no longer hear the humming noise from the engine compartment by the coolant resevoir and it has not come back.
