I don't have a TDI (I have a GTI), but I just wanted to thank you all - because this thread was super helpful in getting my bluetooth issue resolved. When I scheduled the appointment, the dealer was non-committal as to whether there was a TSB for the issue and simply said "bring it in and we'll see." So I was worried that they'd give me a hard time. But when I arrived, they immediately said "yeah, there's a software update."
Because they were so quick to acknowledge the update, I didn't even have a chance to show them the TSB number from this forum. That was a unfortunate, because it turned out that for some reason they tried a different software update first. After an hour, they came out and said "well that one didn't take, but we looked and found this one," and he was holding the same sheets of paper that were scanned into this forum. So once I confirmed that was the update I had wanted all along, they took care of it.
Thanks again for the great detective work!
