Thanks Martin, That's what I am after, I have no interest in the Rim mounted sensors.
I have been able to get "Tyre Pressure Monitoring" to display (with the Secret Menu) under "CAR" with the Ross-Tech Vag-com, but it appears as a dull colour compared to "OIL LEVEL" and "BATTERY CHARGE". All the posts I have read, indicate there is a physical module plugged into the
Q5, and then setup with Vag-Com.
I don't believe it's just a Vag-com adjustment alone.
Do you know if this illusive module exists and if it is available from Audi aftermarket?
Also have asked the Audi Dealer Service Department about the TPMS and through their absence of reply, I guess they don't know or don't want to answer.
