S4 2.7T 6-speed manual
No
Also lost a lower interclooler hose--blew off at track event. I use 5w40 synthetic more often than 5w30. My dealer uses 5w30 synthetic but I change oil every 2000 miles-or after any track events.
A6 2.7T 6-speed manual
No
I belive that I had a leaking DV now replaced with Baileys. Gas milage has inproved I think, still checking.
S4 2.7T 6-speed manual
No
normal turbo sounds (high pitched whine) will be going to 0w30 next oil change
S4 2.7T Tiptronic
No
I'm not sure if I have synthetics or not. Whatever Audi put in it. I wait for the water temp to be 'normal' before driving faster. I wait for oil to be 'normal' before dropping the hammer.
S4 2.7T 6-speed manual
Yes
Bad F hose for months

So far, so good - knock on wood.
S4 2.7T 6-speed manual
No
I have a siren effect and it is somewhat annoying..
S4 2.7T 6-speed manual
No
Note that I had 2 TBB failures, but no turbo failure (clarification)
S4 2.7T Tiptronic
No
Replaced TBB even though the old one was not damaged. Recently installed Bailey bypass valves.
S4 2.7T 6-speed manual
Yes
Did not run chipped all the time... Right hand turbo was the main failure, but when they went to replace they saw that the left hand turbo had a bad seal and was leaking oil into the intercooler.
S4 2.7T 6-speed manual
No
There are no coldown guidelines in the European S4 manual. At least, I couldn't find them.
S4 2.7T 6-speed manual
No
In response to "How hard do you usually run the engine?" I checked normal, because that's how I *usually* drive. However, one of the reasons I bought this car is because of its performance, and I do drive in a performance oriented fashion often (W.O.T.), but not the majority of the time.
A6 2.7T 6-speed manual
No
Best automobile I've ever owned. Period.
S4 2.7T 6-speed manual
No
S4 sold for RS4 after one year and 51.000 Km, A lot of travel in germany at the speed limiter 280km/h (250 real) No problem. Regular hard driving, no problem. No regrets. Lets try the RS4 now.
S4 2.7T 6-speed manual
No
I will be switching to Mobil 1 5w-30 for the winter. But 15w-50 lubricates very well in the summer as long as you can wait for the engine to be up to temp before you drive hard.
S4 2.7T 6-speed manual
No
How about doing this periodically so we can see how the 2001's fall out over time
S4 2.7T 6-speed manual
No
Thus far, no problems.
A6 2.7T Tiptronic
No
Oil has not been changed - will use Mobile 1.
S4 2.7T 6-speed manual
No
I swapped the TBB anyways. No turbo failure yet, but they are beginning to get loud..
S4 2.7T 6-speed manual
No
Love this car and its turbos! I take care of them and they take care of GOING!
S4 2.7T 6-speed manual
No
My numbers may be misleading, because although I haven't had a turbo failure, the dealer replaced my turbos because they were noisy and could potentially fail.
S4 2.7T 6-speed manual
Yes
Blew right hand turbo, car ran great till I totalled it.
S4 2.7T Tiptronic
No
Siren noise has gotten louder with cool mornings, passenger side.
S4 2.7T 6-speed manual
No
UUC VM1 exhaust installed
A6 2.7T 6-speed manual
No
I think this survey is BS. I have had no problems at all. All you are going to find, for the most part, answering this survey is a bunch of paranoids.
A6 2.7T 6-speed manual
No
i'm not sure if the turbo has failed. i do sometimes think the turbo has lost some power...it seems variable rather than consistent. sometimes if i run it hard at high speed on the highway for a while i feel a significant loss of power, and later it seems to come back at least somewhat. i'm not very technical with this stuff, just a feeling.
S4 2.7T Tiptronic
No
I beleive the failures we are seeing are a very small percentage of total satisfied owners.
S4 2.7T 6-speed manual
No
Will be chipping in a few days.
A6 2.7T Tiptronic
No
Only have 500 miles on mine so you may not want to include it.

i drag race the car occasionally and also day to day driving i get into the throttle--but always drive easy the last 1-3 minutes before shutdown!
S4 2.7T 6-speed manual
Yes
The f hose was bad for 4000 miles
S4 2.7T 6-speed manual
No
No problem so far. fantastic car!
S4 2.7T 6-speed manual

Oil was factory fill till 5K Mobil One 15w-50 till 8500 Mobil One 10w-30 since (only ~1000 miles) TBB was changed, but only as a preventive measure.
S4 2.7T 6-speed manual
No
Have the siren sound coming from the turbos when engine is cold.
S4 2.7T 6-speed manual
No
None TBB replaced at 8k, original was OK
S4 2.7T 6-speed manual
No
None of hose had a failure but I did had a seperated hose called "intercooler charge tube". Which only required a refitting.
S4 2.7T 6-speed manual
No
Whistling sound increased markedly around 4k. Pointed this out to dealer, but they say it's fine. Tranny concerns me more right now.
S4 2.7T 6-speed manual
No
MTM Chip is in near future.
S4 2.7T 6-speed manual
Yes
Blew within 20 yards of my dealership after getting checked for hesitation. Car was pronounced fine.
S4 2.7T 6-speed manual
No
my car has 15,000 miles on it now. i have changed the oil every 3000 miles. petroleum up to 8000, and MOTUL 0W0-30 FULL synth after that. will get same at 15K. i do full warm-up and warm-down before/after driving. never owned a chip, but helped test v2MTM unit. i live in Denver, and the air here has been blamed for some turbo failures. recent news indicates that some turbo problems with 2000 cars came as result of a shipping problem where some oil lines got bent.
S4 2.7T Tiptronic
No
TBB FAILURE BUT NO TURBO FAILURE.
S4 2.7T 6-speed manual
No
in colder temperatures (i'd say low 60s F and below), i do have the mysterious "siren" noise. it makes me nervous since the s4 community still hasn't gotten to the bottom of the nature/cause of this noise, but otherwise my S4 has performed flawlessly at all times. =)
A6 2.7T 6-speed manual
No
It'll soon get chipped.
A6 2.7T Tiptronic
No
I have had two bypass valve failures.
S4 2.7T 6-speed manual
No
Chip not changed, only reprogrammed by AUDI themselves. AUDI claims 310hp and 500Nm.
S4 2.7T 6-speed manual
No
None I think the s4 is one of the greatest automobiles ever made. I have driven m3,m5,mercedes,Ihave friends who own all of the above and they cant hold a candle to my s4.When I am not auto crossing or street racing(which i do regularly)I like to cruise around, the ride is just so sweet even with the KW coilovers.I do all of the goodies to my s4 (clean it 2 times a week, mobil 93, cool downs, warm ups, synthetic oil you name it no probs. yet.. As far as oil goes i used mobil 1 15w 50 for the first 2 oil changes then i tried red line 20w 50 at $8 a quart. I think i will go back to mobil. I can find no difference between the 2 mobil is cheaper and has not let me down in the 10 years i have used it..
S4 2.7T 6-speed manual
No
Haven't done first oil change yet, but will move to 0W-30 Mobil 1 soon.
S4 2.7T 6-speed manual
No
Zero problems through 5,900 miles. Replaced the TBB with the new part, but there was no failure. Car has not had ANY problems at all. Stag 2 upgrade.
S4 2.7T 6-speed manual
Yes

Just getting in the data base for the new turbo survey
S4 2.7T 6-speed manual
Yes
The Throttle body boot caused the failure while racing it.
S4 2.7T Tiptronic
No
About to install a Garrett.
S4 2.7T 6-speed manual

Great Car. No Issues so far.
S4 2.7T 6-speed manual
No
I also upgraded the turbos and the intercooler
S4 2.7T 6-speed manual
No
Great so far. Only 3500 miles and loving every one of them!
S4 2.7T 6-speed manual
No
removed fog lights and got new "AVS Shoes"
S4 2.7T 6-speed manual
No
None I was not attentive to the oil temp gauge untill recently. I previously waited until water temp hit normal before I got on the throttle.
S4 2.7T 6-speed manual
Yes
APR Tuned. TBB blew early on. No problems since it's been replaced with the new model. No dramatic failure. The turbos (passenger in particular) sound very loud, enough to scare all passengers.
S4 2.7T Tiptronic
No
Audi's rule!
S4 2.7T 6-speed manual
No
is it possible to present the survey results in graph format?
S4 2.7T Tiptronic
No
Bosch 110 BPV installed ~ same time as APR chip
S4 2.7T Tiptronic
No
enough of this Chicken Little "the sky is falling, my turbo's failing" bullshit! i love my car.
S4 2.7T 6-speed manual
No
Starting to get a noticable siren sound after chip install. Dealer checked out and said normal. Siren sound disappears after engine warms up.
S4 2.7T 6-speed manual
No
My right side turbo did begin to make the siren sound. Knowing from these posts that that was a precondition to a possible failure I addressed this with my dealership. I switched out the chipped ECU for my stock one. They agreed the sound was not normal and replaced both turbos with the updated counterparts. It has only been 1500 miles since (car now has 9000 miles.) Car is running on chip power once again and doing fine.
S4 2.7T 6-speed manual
No
EDL keeps coming on , mech thinks it's related tgo poor battery 1 June 2001.
S4 2.7T 6-speed manual
Yes
I wasn't as cautious with the warm up prior to the turbo failure as I am now. I now wait until oil temp is above 175 before any spirited driving. The Audi lead tech felt my failure was due more to lack of use (read sitting in Boston traffic and having the spindles cook with thier bearings)then from hard use. They also replaced the right head (lost electrode), manifold (cracked), and wiring harness (bad firing) at the same time.
S4 2.7T Tiptronic
No
My car hasn't had any problems yet. Let's just keep it that way :)
S4 2.7T 6-speed manual
No
No problems except a sticking ashtray and a scratched wheel caused by the owner. Still on original Bubblestones with no apparent problems.
A6 2.7T 6-speed manual
Yes
TBB failed at 2000 mi, turbos were loud after that. TBB failed again at about 5000 mi. Audi finally replaced the turbos at about 7000 mi.
A6 2.7T 6-speed manual
No
2001 Replacement for a 2000 lemon. Car seems much better built than the 2000.
S4 2.7T 6-speed manual
No
No problems with turbos despite three drivers schools and lots of autocrosses. i think its the oil, letting it warm up and letting it cool down, same things I have to do with my turbo charged airplane
S4 2.7T 6-speed manual
No
Replaced TBB on spec (no failure). Definite turbo whine when cold, goes away upon warm-up.
S4 2.7T 6-speed manual
No
I am VERY lazy about turbo cool down.
