I have a V-Checker Scanner Pro, bought from ECS Tuning back in June. It’s the VAG-COM they sell for $120. Used only once to check and see if my Audi’s modules were working. Comes with manual and case. $75.
Also have a set (4, four) of TPMS sensors. Part number 1K0.907.255C. VW/Audi, made by Siemens, 3/24/10. All 4 have the valve stem nuts, too. $70.
