Steering column no longer goes up or down, just in and out.

Hello, I have the problem at my Phaeton that the steering column can no longer be set up and down. In and out still goes. Unfortunately, the steering wheel is quite high up and with in a very unfavourable position. I picked up that it can be connected with the memory seats and the coding. I have access to VCDS, but am only superficially familiar with it. Would I be happy if someone had a tip or even a solution.
