Top 10 1999 Audi A6 Questions & Answers

First off, the last of the "trunk sticers" were in Audi 100's, so that was a long time ago. You may find a trunk monkey thou!
Second, any audi dealership can get you your code with your Vin number by useing either Elsaweb or AccessAudi, you do not NEED to take the car in. They just want you to take it in so that they can charge you. A card was supplied with your car from factory with the code,but most people remove the card and loose it or don't send it with the car when sold.
Third, the code IS NOT located on the sticker on the radio, this would defeat the Anti-theft purpose of having a code to unlock the radio if someone stole your radio, "put it on the radio", THINK !!?? Someone may have written it on your radio, but the factory DID NOT.
Each radio has a program procedure that can be found here
http://www.ibiblio.org/tkan/audi/radios/radios.html
find your radio and have the code. 2 or 3 wrong codes will lock you out for at least 1 hour.

You need special keys to remove Audi radios also, if you don't believe me about the sticker on the radio.

You may have a coil pack going bad. They're on the front top of the engine - you'll see them if you follow the spark plug wires back. Do you have any codes from having the engine scanned? If you can get it scanned (AutoZone will do it free), post the codes up and we'll see which cylinder(s) are misfiring. From there, you can swap coilpacks around and see whether the misfires follow the packs or stay in the original cylinders. If they move, you have a bad coil pack or two. If they don't, since you've already changed plugs and wires, I'd see about having the injectors diagnosed to see if any of them are failing.

you have a thermal fault i the abs modulator <ecu bolted onto pump> the rev counter fails because this signal fails to get from 13.8 volts to zero it only manages to get to about 3 volts this is very common on bosch 5 series mine had pt code bosch 0273004285 and is notorious but easil removed and sent to bba here in uk or others in usa you will have to remove wheel then washer bottle then modulator but car stiill drives when removed the esp needs signal from abs and fails at same time also loss of tacho signal puts il light on i tried to find second hand one biut they didnt work have sent mine for repair<you need a microscope to do it> will post when it comes back ps easily confirmed by spraying abs pump.modulator with freex=zer spray did it to mine and fault dissappears untill warm again nb even when cold i bet if you brake hard a couple of times it will fail please let me know if your pt number is same as mine and if this heelps it drove me nuts

If you need to repair the brake module, there is a fantastic article, complete with photos, at http://www.audiworld.com/tech/elec116.shtml

I followed this example for my '98 and now it works perfectly. I found a shop on eBay to rebuild my module (lifetime warranty) for under $200. It took me about 1 hour to pull it off and about 45 min to put it back on with minimum shop tools

Hope help (remember rated this).

if you open the door you want to lock and have a look where the door lock mech is there should be a switch to activate child lock or use a screw driver to turn the switch

if this helps please let me know
cheers

In back side of the radio, (for Audi A4, A6 - year 1999), you will find a blowed fuse = 10A (red colour). Replace it and that's all. Also:
IMPORTANT NOTE: You must have the security anti-theft code for yours Audi Concert radio from the car manufacturer! For Audi Concert the sequence of programming is:
1. Push simultaneous "SCAN" and "RDS" keys until on the screen will appear "1000" displayed.
2. Release keys. No more push on "SCAN" and "RDS" keys because otherwise number "1000" will be considered as first safe code attempt.
3. By the #1 key you will set up the first safe code digit.
4. By the #2 key you will set up the second safe code digit.
5. By the #3 key you will set up the third safe code digit.
6. By the #4 key you will set up the four-th safe code digit.
7. Then push again simultaneous "SCAN" and "RDS" keys for confirm this safe code. On the screen will be displayed "SAFE" notice. Release keys! For few seconds a radio frequence will be displayed. The radio is now ready for use!

• Hi, I can help.

• On that year Audi (A6) the only two lights that would illuminate on your dash will either be for the brake light (top image in the diagram) or a headlight or tail light is out (bottom part of the diagram. So basically have a look at your lights, one of them is out.

• No other lights on your dash have an "X" on them when illuminated.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa

a B5. Look under the front of the seat - you'll see two harnesses there. The yellow one (closer to the center of the car) is the airbag connector. Zip-tie it tightly together, and then have the light turned off (find someone nearby with VagCom to do it for you - a dealer will hit you at least a half-hour labor to do it). Be careful when zip-tying though - the wires are small and the ones on the back could get pinched and damaged.

Hi Jeremy!

WOW! thank you very much about your tips!! I fix my airbag light just moving the yellow wire under my driver seat at NO COST!!

I got Captiva LX 2007 and the airbag lights on for month and I know Holden dealer charge a lot for any repairs!

Airbag light on - fixed now!! Thanks again!

Now i need to fix my Engine light - Holden dealer quote me for 4K-6K to replace the timing chain..

I got quote from the local mechanic for $2400 ---- a lot cheaper!!

Cheers
