    Might be a bit late to the party with this one but check the engine code on the car. Some of the later 3.0 TFSI engines that are still supercharged switched to a different PCM / ECU and that might be your issue. From memory they used a Continental Simos16.x not the more commons Simos8.x that is much more widely supported.
