hi all,

looking for some info as to what the error codes on my dash mean, i know the headlight out warning is on as i had my head light bulbs changed, so presuming they need to be wiped via vcds, but some help on the others would be appreciated, before i give audi $ to tell me!

Looks to me like it's cycling through the self diagnostic. Are you holding the check button to get it to do that?

Mine leaves the icon on the display after it senses a problem. Pressing check tells more about it.
I just tried holding check on my A8 with the ignition on and it does exactly the same as yours.

Have a look at https://www.audiworld.com/tech/elec57.shtml

If you have VCDS do an autoscan. It will tell you if there are any malfunctions.

Yeah that is what I get when holding down the "check" button on the dash. After it's done and I switch the headlights on I get the bulb out warning light staying on, which I am going to get wiped tomorrow. I don't have the vcds software so can't do a self diagnostic. I think I may be ordering it soon though!!

So the cycle it's going through is just a self scan and nothing to be worried about?

As far as I know yes. Either that or both our A8's have a tonne of problems!


I've found it and the Bentley manual to be invaluable. If for no other reason that turning off the bloody seat belt chime.

Haha yes let's hope both our A8’s aren't dying before our eyes! I'll take it to the local mechanic that has vcds and ask him to wipe the error. Hopefully the LEDs I installed today aren't faulty, they are supposed to have a can bus error cancelation chip in them.

I've been looking for the bentley manual and the genuine audi DVD manual that came with the car, can't find the bentley manual for less than $100 and can't find the audi one at all!

Thanks for the help though, let's my mind rest for the rest of the night!

I believe that the Bentley manual on CD is the only service manual available to the general public. $100 is about the market price for it.

Should be okay on Autocheck. It cycles through like that if you hold the button down. Same basic function since my old C3 from 1985.

A bit suspicious on the basic warning though. I wasn't aware the error needed to be cleared. Could be the case on newer or HID ones though; haven't had an headlight issue on either of my newer (HID) Audis in 10+ years. On older Audis when I replaced the bulb at issue and then activated the circuit involved again, the error would clear in the display. When you mention an LED mod, it makes me suspicious (as you are) that there may be something else going on.

I think you are right about clearing the error. I`v just changed my fog lite bulbs and error was gone when I turned them on.

By the way I installed 55W HID`s. Lots of properly directed light. I love them.

Post your Link for the LEDs you used! Depending on your A8's Year and type of LEDs you are using, you will get that Bulb Out Warning and nothing can be done except to remove them and replace with original Bulbs. However, there are only a Few LEDs that will work, so send the Link and I'll let you know. Laters,

These are the lights I got. My local mechanic plugged the car in and saw that they are only pulling 2 watt rather than the required 5 to avoid the error code. I have ordered new ones from autoilumination and if they don't work I can get a resistor wired in to draw the extra power.

My car by the way is a 05 A8 3.0Tdi
