Tpms module d2 a8

[Fredde]

Hello i purchased a a8L d2 last year which has the active tpms system. Wien i got it it had a no communication error with the tpms module. I turned the system off using obdeleven with the plan to deal with it at a later date. Well now it is time. Does annyone know where this module is located? I have looked at some diagrams that seem to indicate it is located somewhere under the dash but it is pretty vauge about the precise location and i dont feel like tearing the dash apart to look for it untill i have some more info.
