Has anyone else had a radiator/coolant system hose failure recently?

My three month old A6 began leaking alot of coolant (onto the floor of my garage) last week. Of course, I immediately took the car to my dealer (in Orange County), where it has now been sitting for over a week for lack of a replacement hose! Apparently, the hose isn't broken or torn, it is defective and is porous to coolant. When my service consultant told me that Audi didn't have the parts in stock in the US, but was expecting some from Germany next week, I asked him if one those incoming parts was mine. No, no guarantee that someone else isn't ahead of me on the list (apparently this is happening quite a bit to other 4.2 owners).

At this point I decided that I really should ask someone at Audi USA for assistance in getting my car back on the road before Christmas. Their consumer advocate said that she'd check with Parts and get back to me. Parts called shortly thereafter and left a message for me yesterday that they were 'looking into it' and would give me a call when they knew where the replacement hose was... Of course, the Parts person who called has Friday off, and no one knows anything else.

Driving a crappy rental car for a week only to find out that they still can't assure me that they'll be able get my car back on the road next week, and not getting any positive closure from customer service at Audi USA is sending my blood pressure throught the ceiling!

Sorry for the rant...
