Hi all, thanks for writing up all of your collective experiences. I recently purchased a 2013 Audi S6 and a day after I drove it home, it did the non-start many of you have described, (no wonder he sold the car). 30+ minutes after driving, cranking and turning over and then dying as the revs fell. Starts if I apply some throttle while cranking.

Car is 100% stock with 78k miles. The turbos have been replaced by Audi at 55K along with the oil separator. I brought it to Audi last week as it needed a new key programmed so I figured I would have them take a look at it. After a few hours as well as consulting some outside sources at Audi, the only thing they could find was a fault in the transmission module. They reset it but of course that wasn't the culprit.

My hope in reactivating this thread is to get a sense for what I should try doing first. I am not very mechanical and its out of warranty so I will be paying my independent Audi mechanic for diagnosis time and I am hoping to point him in the right direction. Have any of you definitively solved the issue with some of the above various fixes?

Thanks in advance.
