With about 119,000 miles on the the car, my 2005 A6 quattro 3.2 started stalling occasionally. Then, while fully warmed up, the performance quickly went downhill. Several stalls within a few minutes, and then alarm lights lit up for failures in the ABS, ESP, and Parking Brake. I had the car towed a long way to an Audi dealer. The dealer reported that they attempted to "set readiness" and that the process failed on the throttle body. They got an error code several times and eventually a pass. They concluded that there was an intermittent failure in the throttle body, so they they replaced it. The car seems OK after the 120-mile drive home and 60 more miles of driving the next day, so the diagnosis and repair, in the short run at least, appear to be correct.

1) Is this a common failure? If so, how roughly how many miles do these throttle bodies typically last?

2) I requested and received the old parts, shown in photo. There's a red rubber band that seems sized to fit around the approximately 2-inch circular throat which houses the butterfly. Is that rubber band really the forty-three dollar gasket?

While not common, it does happen. If the gasket was:06E133073A then yes, it is 33.00 discounted. MSRP is 43.00. What did they hit you for on the Throttle body? That one is mighty pricey.

By the way, what was the resolution on the MMI?

The throttle body price was $1208.25.
Yep, that was the gasket part number.
I wish i weren't having enough issues for you to remember me! ;-)
The MMI failure was fixed by replacement of the J525 Digital Sound System Control Module J525, priced at a cool $1732.

This Audi parts habit is getting expensive. I'm thinking of switching to heroin. It'd be cheaper and probably no worse for my health.

Thanks for the info.

Hopefully, you are past most of the nastiness. Mine went 40k with little trouble, just tires and brakes from 90-130k. If you are maintaining the car you shouldn't have future problems but I would highly recommend finding an independent shop. Paying full screaming retail for parts and labor is enough to cause heart failure. Owning these cars is a wonderful experience while they are running right. Premium fuel, synthetic oil, and marginal fuel mileage is just the entry fee for driving one of the best performing cars made. Keep up your research on the forum the next time you have an issue and I am betting that someone here can probably save you a lot on the next repair. I am in the middle of a nasty timing chain issue with mine right now and without the forum info, I would have junked the car by now. Best of luck.

Waking this thread from the dead. Mine just went on my 2005 A6 3.2 with 160,000 miles on it. I’ll say, it’s running awesome now.

I chased a stalling issue thru the fuel system, then the throttle body finally threw a code.
