Dot Matrix screen In 2002 Audi A6

SOURCE: AUDI A6 RADIO CODE

I just posted a solution for this problem. It comes straight from the radio manual. The dealer should have told you this. If you want him to do it he'll charge money for his time. IF YOU LOST YOUR CODE. THE DEALER CAN HELP YOU OR IF YOU HAVE YOUR 4 DIGIT CODE:

SOURCE: AUdi A6 gas tank button

There is no button to open the gas door from the inside of the car.  As long as the doors are unlocked, you should be able to push in the far right side of the gas door and the left side will pop open. I too spent hours looking for this non existent button..I went as far as to going back to the car dealership.

SOURCE: How do I change the passenger headlight bulb on my 2002 Audi A6?

Here you will see the left headlight we are going to take out, but the same procedure can be applied also to the right one (click will open a bigger photo in a new window)


First, remove the cover circled in green (just take it, it is not fixed with screws), then, with a Torx screwdriver, remove the two screws circled in red


Cover removed


Under (yes, almost hidden) the cables circled in red and yellow there are two more Torx screws, you don't need to unscrew them all, only make 2 or 3 rounds


Particular of the screws under the circles in the previous photo (sorry for the bad focus)


Last, we have to remove the power connector. To remove it, pull the little plastic block lever circled in green and then, while holding it, pull out the whole connector (in red). After that the headlight is free, and you can take it out from the chassis


Et voila', headlight removed :) Red circles are for the vertical offset control, don't touch them unless you know what you're doing. Lights are located under the black plastic covers

Do a three-part Seafoam treatment to see if it helps. You can buy Seafoam at a parts store or in the auto section of walmart. Get two cans.

Pour one entire can into the gas tank. This will clean the tank, lines, filter, injector pintles, etc.

With the other can, pour half into the oil, drive 60 miles or so, and change the oil and filter. This will remove oil sludge, varnishes, and deposits.

Remove the vacuum line from the vacuum pump on the back of the engine (or any other vacuum line into the engine), start the car, and with someone holding about 2000 RPM on the engine, allow the engine to **** up the last half can of Seafoam. It will stumble and run rough. Let it run for about 10 seconds after the Seafoam is sucked up. Then shut it down for 10-15 minutes so the Seafoam can go to work breaking down the carbon deposits in the engine's vacuum system. Then restart the car, let it idle for a couple minutes, then rev it several times to 4-5000 RPM. You should be seeing a LOT of smoke out the back of the car. Let it idle again and rev it up every couple minutes. Do this until you're not seeing much or any smoke. A little bit the next time you drive is fine - it'll finish burning off.

I've done this on many cars (most of them Audis) and it's made nice differences in smoothness, economy, and a little power even.

Also, make sure your other fluids are topped off, your air filter is clear and clean, the tires are inflated properly, and that you have no stored codes in the computer (stop at AutoZone and ask them to scan the ECU for codes - some latent codes won't trip a check-engine light but can alter the car's performance).

30,000 mile plugs but it doesn't meen they need replacement I work for chrysler I would wait till about 50 or 60 thousand remeber just because there is not a problem doesn't meen they should not be replace at the recommened intervals. they are considered a wearable item. when you do the plug do the wires. words of advise when doing the ignition wires do ONE WIRE AT A TIME it will save u from a big headache.
