Sorry you had to deal with that. You should look up the Audi Bulletin AWA-21-01 where certain model have an extended warranty up to 10 year/ 100K miles to cover this repair. I'm glad Audi identified this but it is a real problem. My A5 was at around 50,000 and it happened. Now I hope to get it fixed in July. Such a long wait.
