Dreamcatcher, Do you happen to have a picture of said chafe? My car is showing the exact same issues, U140E and also has a stored code C2115 - Dynamics Sensor Supply Voltage High... I've got the console all apart, and don't see anything obvious from the sensor to the firewall....Well after almost 1 year of investigation I've finally found the resolve for U140E.
It turns out that my CANBUS fault was a short to ground on the dynamic sensor power wire and it caused the CANBUS to go haywire. The wire was chaffed to chassis and is now fixed.
