Harmonic Balancer Issue



I am trying to find out an answer for my tech as he has never come across this problem. He replaced a harmonic balancer on a 2000 A4 and the code on the DIC is "traction control warming up".
He gets the code for the EPCM #1243 and for the left sensor #1234.
Any idea on how to proceed?
Thanks in advance,
