DCT Transmission Fault

Hi all, yesterday I just did my engine oil and dct oil change cuz I hit the 80k mark. Everything was fine driving back from the workshop, but when I got home and drove into the garage, the car jerked and this error came up. Was also experiencing the traction light turn up for afew seconds while driving. Could they be inter-related? Anyone experienced this before?
Hope to hear from you guys. Thank you.

These are the errors i got from Carly OBD2 diagnostics.

There are two shaft speed sensors in the DCT and and a wheel speed sensor on each of the four wheels of the car
The car is basically saying that the speeds dont tally ie what the gearbox is saying should be happening is not what the DSC?ABS is saying.
It could be something simple as an ABS sensor or wiring issue, but could be as complex as a DCT shaft speed sensor being disturbed.
Given the ABS sensors can be accessed easily id start there.
