Re: Ask me anything about Audis!
Hi Beezer,
A couple of questions. Does the cut off happen in every gear or just certain ones? The stock rev limit is 6600 +/-100 so there is something else going on here.
When it does hit the limit, do the needles on the dash almost seem as if they are resetting themselves? Early TTs had cluster problems where this very exact issue would occur.
Has the garage scanned the car for any codes?

Re: Ask me anything about Audis!
By any chance do you have access to VAGCOM? You can run an output test on the flaps to see whether they are operating within spec. That would be the first step in determining what the issue may be.

Re: Ask me anything about Audis!
Hi
I purchase a 2000 quatra A6
check engine light was not on
About a week after I got it home it came on. Had it checked on computer and it stated random multiple cylinder misfire detected.
Engine light has been reset but continues to come back on as does the air bag light
which I also reset but comes back on sometimes.
Complete tune up included: plugs, injector cleaning,
codes are: 301-303
Car is running pretty good. Cannot tell if its missing.
Thanks

Re: Ask me anything about Audis!
Hi, I'm Back. Good battery and Alt. tests ok. Have swapped coilpacks, plugs, injectors and still get a misfire cylinder 1 and or 2 and random misfire codes. Is it possible that the wiring is bad somewhere? Also I've heard that the ECM/ECU go bad on these. Could that cause it to run smooth after about 30-60 seconds only to run rough once give it gas and or put under load? I can see the case is hard to open (somewhere I saw to open it with a dremel cutting slots for a flat head screw driver into the bolts holding the computer in place?). I notice the # on the case is 8e0907411 and I pryed a little on the case to see the computer # is 8e0909518 bc. Also the wiring harness is 8e1971074. When I search EBAY for used parts I see the ECM/ECU for sale. I was wondering about the letters following the harness tho. I can find ending in 1074 however all for sale have letters after the #'s and mine doesn't. Does this matter? Will the harness be compatible? Thanks and no rush. I've got other means of transportation in the mean time just trying to get her back on the road. Thanks Jesse

What motor is your A6? Do you have access to VAGCOM to gather more specific data regarding the misfires and airbag light?
I noticed you changed the plugs...but the misfire is on 1 and 3. Can you possibly swap coils and see if the misfire follows?

The ECUs have known to be problematic but before we jump to condemn it...can you do a smoke test to ensure there are no issues with vacuum/air leaks?
