Dyno Question
 

I had my 2010GS A6 dyno tuned and shortly after I got the TCS service traction control system msg. I read ALL the DTC codes with a Tech 2 and there where three for each front wheel sensor. We did three pulls on the dyno.
I cleared the codes and have only put 20miles since but so far no codes. It make sense to me that with the car strapped down and the rear wheel spinning that I might get these codes.
Anyone else ever seen/had that issue after a few pulls? So far no steering wheel position sensor fault.
Thanks Steve

Yup. Normal. Back tires spinning. Front tires not. Both my c6z did it after dynoing them. Cleared themselves as soon as I drove the car.

Thanks for the reply. For some reason mine did not clear when I drove it around for almost a week. It kept coming back after the car warmed up.
