Took delivery of an 8V S3 a few months back. For search purposes, I encountered a problem with the Data Module at the same time as my 3 months Audi Connect ended, appears to be complete coincidence. The car failed to pick up that a SIM card was in the slot and every time I went into the connections menu, it would have the option to turn on the data module. Turning it on did nothing. Resetting the media centre did nothing. Took it into the dealer (under warranty anyway) and they diagnosed a broken data module. Glad I didn't have to pay nearly a grand for a new one & fitting! I presume it's a rare occurrence as I couldn't find much on this. For assistance, the part number was: 8V0 898 407 and listed as a 108960/Repair Kit.
