Pre- Safe Function Limited / Traction Control Lights
Last week I got a simultaneous "Presafe functions limited, see operators manual" and "Traction control currently unavailable" messages on the screen. TC, TC off, and BRAKE lights all illuminate on the screen.
Car goes into limp mode and cant accelerate well enough to drive safely. Issue is intermittent and comes on and off. Sometimes the issue will go away as soon as the car starts rolling first thing in the morning.
Dealer says it needs a traction control hydraulic unit ($3450). Did not say anything about sensors in bumper, etc.
I had an indy shop pull codes and there were several possible related CAN BUS codes:
1. u012100 [Current/History] Communication with ESP has a malfunction
2.1 C101500 [current/history] The values of component 'A7/3 (traction system hydraulic unit)' are faulty.
2.2 C232000 [stored] one or more signals sent from control unit 'N73 (electronic ignition lock control unit)' via the CAN bus are implausible
2.3 C232100 [stored] one or more signals sent from control unit 'N73 (electronic ignition lock control unit)' via the CAN bus are implausible
1 U041500 [CURRENT/HISTORY]Implausible data were received from control unit "ESP®". _
Do these codes line up with the dealer recommendation? It has traction control codes, but also bumper sensors.

These units are all over ebay (used) in the $200-$300 range. Would you know if it would need to be programmed to the car after replacement?? If not I will probably DIY this.
I am dropping the car off for a more thorough troubleshoot at the indy dealer that pulled the CAN codes and will see if they have a similar recommendation.
Thanks
