Estreed: With Post #1362 and my trans problem A6/4.2L (Post # 1367)...You are right, I replaced the TCU and the ran fine for >3 mile or so, once it learned all message from the ECU, same problem ...the limp-mode with occational jerk shifting with no 1st and 2-3 hard upshift etc. It apears that its the torque converter and/or 1st gear, but then all 1-5 shift in fast fashion (before I hit 3000-3500 rpm) with jerks which sugests that it may very well be Torque converter as you've explained...Can you recommend a Shop (USA or Europe) to get the TQ Converter REBUILD and at what cost. Also How do I get it out, how many hours will it take ? Many Thanks jeffwhite_usa yahoo.com

I bought a 99 A8 quattro a few years back and the transmission has had the issues you posted (http://townhall-talk.edmunds.com/direct/view/.ee9e503) with the exact symptoms. I left my car at the dealer for a week, they couldnt figure it out (although they still wanted to charge me 8 hours labor). I had coverage on my powertrain the entire time and unless I paid someone $4k to take my transmission apart, there was no way I would have had the tranny covered. If the dealer had done their diligence and given me a diagnosis, I could have had everything covered with $100 out of my pocket. Now I am scrambling to solve the problem before I do worse damage. Is there any specific information I should ask the mechanic to look for? Do I actually need to replace the tranny, or can I get away with just the TC clutch and valve body? It seems that in 2002 model years, these problems subsided, as if the design was changed to eliminate this problem. Most of us on www.audiworld.com have the same exact problem. Thanks again for the great post! |

I have 2005 A8L W12. I'm considering installing Dension iPod interface soon and wonder if anybody has seen if it works well. If you know, does it replace the CD player? I've not talked with a Dension rep but only to a couple guys at the dealership. Thanks

I recently purchased a 2005 Audi 8L which I enjoy immensely. I do however get a lot of road noise which appears to be coming from the tires. I took the car to an Audi dealer in TN which is near my summer home but not my where I purchased the car. They were absolutely no help and told me the tires were cupping (whatever that means) and creating the road noise. The tires are Pirelli Four Seasons and were new at time of my purchase a few months ago and have been noisy as long as I have owned the car. I am wondering if this is chrachteristic of the car or is it normally a quiet car.

| I am running Michelins on 19" rims. Very quite. Cupping is usually caused by misalignment and can be noisy. Sounds like your original dealer should check it out. If it was a Certified Pre-owned used car from an Audi Dealer they have a very extensive check list which should have covered appropriate wheel alignment. Good luck. | |
| I have a radar detector plugged into the cigarette lighter on my A8. The problem is the lighter does not shut off when the ignition is turned off. Sooner or later I know I'm going to wake up with a dead battery because I forgot to unplug the detector. Ant thoughts on a fix? | |

Replying to: bobwash (Oct 12, 2007 6:15 am) Get rid of the Pirelli P6's. They're pretty poor tires and numerous complaints can be found about them. Go to a place like tirerack.com and you can see all the reviews on every tire that will fit your A8. Your A8 will ride a lot better with different tires. |

I am in the market for a used luxury cruiser. To me the "quietness" of the car while traveling at high speeds is a big factor. I am juggling between s500 and a8 and really like the a8 due to its elegant interior and awd. I have been hearing alot about windnoise and road noise in the a8's. I currently own a 04 lexus rx330 and it is very noisy. please give me your opinion about how the vehicle is on the highways and how loud or quiet it really is. im looking particurly at 04 or 05 model. your help will be appriciated.

Just came out of two Lexus GS 300's into my 04 A8L. My wife say's it is the quietest car she has driven. The 19" Michelin Pilot 255/40 ZR19 A/S the recommended 41psi are amazingly quite and smooth. The grip is fantastic and they look great. It's a techy' automobile and ton's of fun. Check the AutoWeek Dec 17, 2007 issue for a discussion of the A8L and S class MB and the 460L Lexus. The Lexus is smooth and not as much a drivers car in my opinion. The website is autoweek.com/driverslog for more comments. Enjoy ..... p.s. the Scottsdale Audi dealer is truly outstanding.
