I have a 2015 S550 with the following error

"The charge air temperature sensor (cylinder bank 1) has a short circuit to positive'

Feel a bit stupid asking this but can anyone tell me where this sensor is located please? Or the MB Part number

I thought it was the one going into the air filter box, but, after changing that sensor, I discovered that one was called the 'Intake Air Temperature sensor'

thanks in advance
