I had a similar problem with my bimmer's traction control bc i had wheel+tires that were a bit too big (speedometer was off too).
It's just a thought.
Edit: Also the most recent flash for the DCT was also for the ABS/traction control. So maybe there is something at issue there.
Good point that the latest flash affected ABS, I forgot about that. I'll have to try this, but I doubt it'll solve my issue.
Also, I don't think the wheel size has much to do with TC/ABS as long as all of the wheels are the same size since it's checking for tires slipping and not revolutions vs true speed.
I could see lighter/heavier wheels causing issues if it's outside of the car's expected loads / parameters... that said, I think we're experiencing a leaking clutch seal (internal, most likely, since I have no fluids outside my bell housing as of yet).
