My 2015 XK vert has the Adaptive Dynamics Fault message. I pulled the code C1B14 which is Sensor Supply Voltage A-out of range. I reviewed all the sensor data and the only ones that are out of spec are the sensor supply voltages, which are both about .5 volts low. Any suggestions besides replacing the adaptive dampening control module? If one is available new, it's pretty expensive.

 

Have not checked what is this code associated with, but my first reaction would be height sensor fault (at one of wheels).

 

The height sensors all showed the same voltage. It was low but I'm thinking that's because the supply voltage is low.
