Ask them to adapt the cluster for the stereo

took the car back to audi this morning. They spent best part of an hour looking into the problem. They said the dash is adapted to the stereo although they had their senior technician look at the problem but could not figure out where the fault was.
They said as I will need a new stereo due to lcd screen not lighting up they can order me one and take it from there. Still not sure and not willing to spend £270 for an exchange stereo until i'm sure the stereo is at fault. Unfortunately they had no other stereo to try with my car to prove where the fault was.

Thanks for your help, need to find someone near by who's concert I can try in mine.
