I have been looking at threads on here about retro-fitting indirect tpms to A3/S3. I have a question for anybody that's done this mod. i've retro-fitted tpms on a 2013 TTRS before but looking through here there's no mention about fitting a tpms module, just activating it through vcds to operate through the dis.is this correct? the idea of the module is to remember the settings/pressure etc but I can't understand how this is possible without a module as seems to be suggested here. I pick my S3 up in march ( without tpms fitted) so this model does not have a reset button on the dash and so is obviously controlled by the dis.but where's the memory held? thanks for your help guys. incidently I have a copy of elsawin but the 2014 is not on there as is too new to be listed yet.
