Car dies everytime I try and start it

That's fucking nice. And how much does an alternator cost? Do you know where its located? Is it easy to change?

Bad alternator. At 9-10V is clear that cars electonics are drawing from battery during each drive. Slid 14-14.2V required during proper alternator charging process. Could be just a bad regulator, but still requires an alternator pull. Best to put front clip in service position for the R&R erffort.

#1 - replace/rebuild alternator
#2 - have battery power cycled at shop to see if it has been compromised as a result
#3 - replace battery if test fails in #2.
#4 - keep enjoying your ride.

Therein, as they say, lies the rub.

AoA doesn't stock them anymore (call around, you may find a stealership with one sitting on the shelf), and OE suppliers I've found are selling an Interchange part that doesn't interchange properly. If you can stomach having your RS6 down for a week or so, you could have your Alternator pulled and send it off for rebuild - I've used Kaestner Auto in Wisconsin, and they've been awesome thus far. They're the ones who found the issue with the non-interchangeable part - the pulley shaft is too small of a diameter and doesn't stick far enough out of the alternator to have the proper pulley mounted. As for location/changing - the alternator is under the engine and is an enormous pain in the ass to get to / R&R. I took mine to a local shop, they charged 6 hours labor and that was on the low side since they know me and have worked on my cars before.

Good luck!

i have my own mechanic shop at a bunch of lifts i can do the job myself. my rs6 has been sitting in a temp. garage for months i only take it out for shows/weekends. the problem here your saying is its very hard to find. you think i should just change the regulator and the battery see if its gonna work? i dont wanna drop a lotta money if its an easy fix.

Google "site:rs6.com alternator"...you'll get plenty of info, although looks like Erik spelled it out.

Hey, don't complain too much, my car was leaking coolant, and just sprung a fuel leak down by the pumps...
