Audi q7 codes help

[D88A6]

Hi all,

Attached is 2 photos of 2 codes on my q7. The lights on are the orange traction control light and abs light.

 

Just wondering has anyone had the same problem and had a fix or can anyone help in anyway.more I know maybe less stressed with the car I will be.heard it is an expensive fix from a garage but he can't say cause he want to plug it in. Even though kwik fit plugged it in and told me these.  Thanks in advance
